OPERATION GENERAL PURPOSE The 6400 Series Cultivators are intended to be used for general purpose row crop cultivation. They can be used for throwing up beds, mulching existing beds and incorporating chemicals. These cultivators with regular equipment are fully tractor carried when lifted. CAUTION DO NOT ALLOW ANYONE TO OPERATE THIS CULTIVATOR WHO HAS NOT BEEN TRAINED IN ITS SAFE OPERATIONS. CAUTION DO NOT OPERATE THIS CULTIVATOR WITHOUT READING AND FULLY UNDERSTANDING THIS OPERATORS MANUAL. CAUTION TO AVOID INJURY: DO NOT LUBRICATE, ADJUST OR REPAIR THE CULTIVATOR WHILE IT IS IN OPERATION. CAUTION USE SMV EMBLEM WHEN TRANSPORTING, TO WARN VEHICLES APPROACHING FROM THE REAR. COMPLY WITH ALL STATE, FEDERAL AND LOCAL LAWS WHEN TRANSPORTING CULTIVATOR ON THE HIGHWAY. PREPARING THE TRACTOR It is recommended that tractors be equipped with Rollover Protective Protection Systems (ROPS), enclosed cabs and seat belts be used in operations. Tractor wheels must be set to run approximately in the center of the rows. for example, if crops are planted in 36-inch (806) 745-0384 Page 8 P/N L50012751 rows, the center of the tractor wheels will be set 72 inches apart. Measure from center to center of tires, then from center of tires to center of tractor to make certain the tires are equally spaced from the center. Weight may need to be added to the front end of the tractor for transport stability and steering control when operating. Refer to tractor operators manual for the correct procedure for adding weight. NOTE Front end weight may not always maintain the required stability if the tractor is driven too fast over rough ground with the cultivator in raised position. Be safe and drive slowly under these conditions. Rear wheel weights may be necessary to eliminate excessive wheel slippage or for stability in rough or hillside fields. Refer to your tractor operators manual to determine the correct amount of weight to add. PREPARING THE CULTIVATOR At the start of each cultivating season, the following procedures should be carried out. Clean off any dirt or grease that may have accumulated on moving parts. This will prevent abrasive action that could cause excessive wear. Thoroughly inspect the cultivator for loose or worn parts and adjust or replace as necessary. Inspect wheel bearings in gauge wheels and repack with wheel bearing grease if necessary. Before operating the Cultivator be sure it has been properly lubricated as described in the SERVICE section. OPERATING SPEED The operating speed is determined by soil conditions, plant growth and personal preference. Speeds of 5-8 miles per hour are usually most desirable. 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 BIGHAM BROTHERS, INC. CULTIVATING PATTERN For precision cultivation, the same group of rows that are planted in one pass across the field should be cultivated in one pass across the field, and preferably in the same direction that they were planted. NOTE If hitch components are not centered on tool bar, it may cause the Cultivator to be unstable when lifted or cause damage to Cultivator. HITCH POSITIONS 3-POINT HITCH SELECTION The position and location of the hitch is determined by the hitch category of the tractor. The hitch category may vary from tractor to tractor. Check the hitch category of the tractor to be used and refer to STRAIGHT and OFFSET HITCHES or WIDE SUPPORT HITCH for proper setup. Be sure when changing tractors to check that the hitch is set up properly. There are 3 styles of 3-point hitches available for the cultivator: the straight hitch (bolt on), offset hitch (bolt on), and a wide support hitch (for over 300-inch tool bars). The straight and offset hitches can be mounted on the tool bar to allow clearance for components being attached to the bar. The HITCH CHART below is used to determine which hitch to use. This will depend on the category of the tractor hitch, the row spacing desired and whether used with or without row gangs. STRAIGHT & OFFSET HITCHES (Refer to Fig. 1) CATEGORY II QUICK HITCH - Install the mast bolt and bushing in the third hole from the top of the hitch mast. Assemble bushings and pins in the lower hitch brackets. CATEGORY III QUICK HITCH - Install the mast bolt and bushing in the second hole from the top of the hitch mast.

CAUTION ALWAYS LIFT THE TOOL BAR CLEAR OF GROUND BEFORE FOLDING OR UNFOLDING. FAILURE TO DO SO MAY RESULT IN DAMAGE TO ANY GROUND ENGAGING COMPONENTS THAT MAY BE MOUNTED ON THE TOOL BAR. WARNING STAY CLEAR OF RAISED WINGS. SHOULD WING FALL, INJURY MAY RESULT. AVOID CONTACT OF RAISED WINGS WITH ELECTRICAL POWER LINES. CONTACT CAN RESULT IN SERIOUS INJURY OR DEATH FROM ELECTRICAL SHOCK. ALWAYS LOWER WINGS BEFORE UNHITCHING FROM THE TRACTOR. SHOULD TOOL BAR FALL OVER, INJURY MAY RESULT. WHEN TRANSPORTING WITH RAISED WING SECTIONS, ALWAYS INSERT PINS IN THE TRANSPORT BRACES. INJURY MAY RESULT FROM ACCIDENTAL LOWERING OF WING SECTIONS. AVOID CONTACT OF RAISED WINGS WITH OVERHEAD OBSTRUCTIONS. CONTACT MAY RESULT IN INJURY. P.O. Box 3338 Lubbock, TX 79452 BIGHAM BROTHERS, INC. STABILIZING CULTIVATOR & TRACTOR The cultivator can be stabilized to resist excessive side-sway by using a coulter attachment or tractor hitch stabilizer (sway bar) attachment. The coulter attachment is the superior stabilizing method and is highly recommended for crops planted on contour or rolling land. NOTE Do not install tractor hitch stabilizer (sway bar) while using a coulter. The cultivator must be allowed to float sideways within the normal limits of the hitch. The folding tool bar allows folding of the outer portions (wings) for portions (wings) for easier transporting. Transport braces must be used and transport pins in place when transporting. The folding tool bar may be used as a rigid bar by inserting locking pins. The outer portions (wings) may be allowed to float by adding optional gauge wheels to tool bar wings and removing locking pins, blocks and shims. (Fig. 3) NOTE When a coulter is not used, be sure the tractor hitch stabilizer or sway bar is installed and properly adjusted. RIGID COULTER For most conditions a single rigid coulter (Fig. 4) located at the center of a 100 inch tool bar will provide adequate stability. For usual conditions GAUGE WHEELS An optional gauge wheel attachment (Fig. 3) is available. The attachment includes left and right assemblies (tires not included). Assemblies are mounted an equal distance from the hitch and positioned in the row middle. Adjustment may be required to maintain gang pipes parallel to the ground. Gauge wheels may be adjusted (raised or lowered) using the turnbuckle on the arm assembly. Gauge wheels must be adjusted to the same height for proper operation. LEVELING CULTIVATOR After mounting the cultivator to the tractor, use the tractor hitch-system to level the tool bar from side to side. Tractor top link should be adjusted to position the tool bar in a vertical orientation. (806) 745-0384 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 Page 11 P/N L50012751 BIGHAM BROTHERS, INC. with 188 inch and longer tool bars, two rigid coulter attachments should be used. When using two rigid coulters, coulter adaptors are required. Normal coulter penetration is 3 inches to 5 inches. On hard soils the coulter should be adjusted to run only 2 inches to 3 inches deep to prevent the coulter from holding the gangs out of the ground. The depth of the rigid coulter is adjusted by raising or lowering the coulter arms. The coulter blade can be adjusted right or left by loosening the axle nut (Fig. 5, Item 1) and by loosening or tightening the opposing nuts (Item 2) on the axle as shown. out of the ground. The spring loaded coulter is adjusted by raising or lowering the set collars on the spring rods. In soft soils, adjust the coulter to keep the hub from running in the soil by dropping the bottom set collars to their lowest point and positioning the top set collars 5 inches below the top of the rod. The coulter blade can be adjusted right or left by loosening the axle nut (Fig. 5, Item 1) and by loosening and tightening the opposing nuts (Item 2) on the axle as shown. NOTE When two or more coulters are used, be sure NOTE each coulter is running true and parallel. (See When two or more coulters are used, be sure above for adjustments). each coulter is running true and parallel. SPRING LOADED COULTER For most conditions a spring loaded coulter (Fig. 6) located at the center of a 100 inch tool bar will provide adequate stability. For usual conditions with 188 inch and longer tool bars, two spring loaded coulter attachments should be used. When two coulters are used, coulter adaptors are required. Normal coulter penetration is 3 inches to 5 inches. On hard soils the coulter should be adjusted to run only 2 inches to 3 inches deep to prevent the coulter from holding the gangs (806) 745-0384 705 E. Slaton Rd. Page 12 P/N L50012751 GUIDE CONES Guide cones are used in one or more pairs to provide accurate guidance for precise cultivation in bedded crops. The guide cone attaches to the tool bar as shown in Fig. 7 with the cone riding against the opposite sides of the bed. The guide cone depth is adjusted by raising or lowering the guide cone arms. P.O. Box 3338 Lubbock, TX 79452 BIGHAM BROTHERS, INC. NOTE Due to loads imposed, use two guide cones on 2 and 4 row units; four guide cones on 6 and 8 row units; and six guide cones on 10 row or larger units. Do not operate guide wheels with any other stabilization device. They tend to operate against each other and damage may result. NOTE Do not operate guide cones with any other stabilization device. They tend to operate against each other and damage may result. Guide wheels are not designed to support the weight of the cultivator and should never be used as gauge wheels. NOTE NOTE NOTE Guide cones are not designed to support the weight of the cultivator and should never be used as gauge wheels. GUIDE WHEELS Guide wheels are used for precision cultivation in flat planted or bedded crops. The guide wheels are mounted on the planter tool bar as shown in Fig. 8 and make a V-shape depression in the row middle as the crop is planted. The small spike runs ahead of the wheel and loosens the soil so the wheel can penetrate adequately. The guide wheels are then transferred to the Cultivator tool bar (Fig. 9) and set to run in the previously formed V-shaped depression allowing the row gangs to be set very close to the crop. The spike is left on the guide wheel assembly, to give added stability to the cultivator. (806) 745-0384 705 E. Slaton Rd. SPLIT ROW GANGS The function of the split row gang (Fig. 10) is to control weed growth and condition the soil in the crop row area immediately adjacent to the crop row. The crop will always be between the P.O. Box 3338 Lubbock, TX 79452 Page 13 P/N L50012751 BIGHAM BROTHERS, INC. split row gangs. There are three types of row gangs, the split row gangs with straight tines (Fig. 11, Item 1), the slicer tine split row gangs (Item 2) and disc row gangs (Item 3). The two halves of these row gangs can be used in a number of positions. For certain conditions, such as crust breaking, spider gangs are mounted close-in and without any angle, so they will run straight. In some types of soil, when heavy rains follow closely after planting, it is desirable to run spider gangs opposite the normal direction to penetrate the heavy crust and lift them off the row. NOTE: Soil must be fairly free from trash and hard clods for this operation. A variety of settings may be obtained by experimentation to fit individual crop and soil conditions. A wide range of spacing between the inner spiders of the gang halves may be obtained by using the slots ih the beam plates and the holes in the row gang arms. The beam plates may also be mounted in alternate positions on the beam when necessary. To initially set the spring tension on the row gang support, position the top set collar 2 inches below the retaining nut at the top of the spring rod. Position the bottom set collar 3 inches above the lowest point. This is a good starting position for a cultivator in flat planted crops. Additional adjustments may be necessary to refine the settings for inidividual crops and fields. The spring pressure is increased by raising the bottom set collar. For additional pressure, the sping rod is transferred to the additional hole in the lower parallel linkage. The split row ganags are adjusted according to the type split row gang, crop, condition and operation being performed. For typical settings of split row gangs in small crops, large crops and bed planted crops see CULTIVATOR ADJUSTMENTS. When the crop becomes too high to use the row gangs, the entire row gang and support assembly should be removed from the tool bar in order to permit maximum clearance for late cultivation with the rear gangs. REAR GANGS The function of the rear gang (Fig. 12) is to remove weed growth, mulch and condition the soil in the area between the crop rows. There are three types of rear gangs, the 14.5 inch slicer tine rear gang (Fig. 13, Item 1), 16 inch slicer tine rear gang (Item 2) and 16 inch disc gang (Item 3). The slicer tine gangs are less sensitive to the angle of operation and work best where high residue does not exist. The disc gangs work good in high residue and are more aggressive, (806) 745-0384 Page 14 P/N L50012751 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 BIGHAM BROTHERS, INC. yet more sensitive to the angle at which they operate. The operation and setup of these gangs is the same, except for the angle of the gangs. NOTE In order for cultivator to operate properly be sure that all slicer tine gangs are of the same size. Gang pipes (Fig. 14) must be parallel with the ground in order for the row gangs to penetrate the soil correctly. Adjust the tractor top link until the tool bar is vertical with the ground as shown in Fig. 14.To initially set the spring tension on the long gang pipes, position the top set collar so that the setscrew is seated in the depression provided in the spring rod. Adjust the bottom set collar up until the spring is held firmly, but not compressed. To set the short gang pipes, position the top set collar to its highest position and tighten. Adjust the bottom set collar to leave 1/4 inch movement of the spring. These settings are good starting positions for cultivators in flat planted crops. Additional adjustment may be necessary to refine the setting for individual crops and fields. The rear gangs are adjusted according to the type split row gangs, crop, condition and operation being performed. For typical settings of rear gangs see CULTIVATOR ADJUSTMENTS. For setting of rear gangs when mulching beds se BED MULCHING. (806) 745-0384 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 Page 15 P/N L50012751 BIGHAM BROTHERS, INC. SLICER TINE SPLIT ROW GANGS A typical setting for cultivating small crops is shown in Fig. 15. The split row gangs (No. 1 on the right and No. 2 on the left) should be adjusted with the rear of the spiders angled to the inside to throw soil toward the crop. The rear gangs (No. 1 on the left and No. 2 on the right) should be angled sufficiently to remove all weeds as the gangs slice the soil away from the crop. A level seedbed can be easily maintained with this setting by using sweeps on the end of the long row pipes to sweep the middles and push some soil back toward the crop. This setting allows high speed cultivation. A typical setting for cultivating large crops A typical setting for cultivating bed planted crops is shown in Fig. 17. The split row gangs (No. 1 on the left and No. 2 on the right) should be adjusted with the front of the spiders angled slightly to the inside to move soil and weeds away from the crop. The rear gangs (No. 1 on the right and No. 2 on the left) are positioned on the pipe supports so that all spiders or disc penetrate the soil an equal depth. The gangs should be angled sufficiently to remove weeds while moving the soil toward is shown in Fig. 16. The split row gangs (No. 1 on the left and No. 2 on the right) should be adjusted with the front of the spiders angled suffiently to the inside to remove all weeds while moving the soil away from the crop. The rear gang (No. 1 on the right and No. 2 on the left) should be angled sufficiently to slice out the weeds while moving the soil toward the crop. Sweeps may also be used with this setup. (806) 745-0384 Page 16 P/N L50012751 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 BIGHAM BROTHERS, INC. the crop. For furrow or lister planted crops the No. 1 gang should be on the left and No. 2 gang on the right, in order to move soil up the hill. For crops such as Irish potatoes, do not run the inside spiders or disc of rear gangs too close to the crop. Sweeps may also be used with this setup. DISC ROW GANGS (Repair Parts Only) A disc row gang is used when precision is desired in barring off small crops. A typical setting for cultivating small crops is shown in Fig. 18. The disc row gangs should be angled to throw dirt away from-the crop and should be moved toward the crop until the desired condition is achieved. A single disc on each gang may be used instead of two by using a spacer. A disc and a spider may be used on each gang if desired. The rear gangs (No. 1 on the left side and No. 2 on the right) should be angled sufficiently to remove all weeds as the gangs slice the soil away from the crop. A level seedbed can be easily maintained with this setting by using sweeps on the end of (806) 745-0384 705 E. Slaton Rd. the long row gang pipes to sweep the middles and push some soil back toward the crop. This setting allows high speed cultivation. BED MULCHING For mulching heavily crusted beds with large weed growth, refer to Fig. 19. Bed rippers are recommended for shaving the bed tops instead of the split row gangs. The rear gangs (No. 1 on the right and No. 2 on the left) should be set at the maximum angle possible and tilted so that each spider penetrates the bed an equal depth. Under less extreme conditions the rear gang angle and pressure are less and the split row gangs can be used satisfactorily to tear down the bed tops. The split row gangs should be set the same as for use with bed planted crops. When the row gangs are used to mulch the bed tops, the pressure spring must not run completely compressed and the spiders should not run completely compressed and the spiders should not be run up to the hubs. This would result in damage or excessive wear. The rear gangs should be positioned so they work as near to the bottom of the bed as possible. To fully mulch the furrows between the beds, a sweep should be used in the bottom of the furrow as shown in Fig. 19. P.O. Box 3338 Lubbock, TX 79452 Page 17 P/N L50012751 BIGHAM BROTHERS, INC. INCORPORATING CHEMICALS The 6400 Series Cultivators can be used to incorporate chemicals in either a band or broadcast. For broadcast incorporation in bedded crops (Fig. 20), the split row gangs should be set close together and angled to throw soil out from the center. The rear gangs (No. 1 on the right and No. 2 on the left) are positioned on the pipe supports so that the spiders penetrate the same depth. The gangs should be angled to move soil back towards the center and to lap over in the middle. In flat planted crops, the gangs will be set the same as for bedded, except gangs are not angled on gang pipes. For band incorporation mount a long gang pipe over each row and two rear gangs (No. 2 in front and No. 1 in rear) on the pipe about 4 inches apart as shown in Fig. 21. Angle the gangs about 5 degrees in opposite directions so that rear gang picks up soil moved by front gang and places it back into desired band while thoroughly mixing the chemical with the soil. As a general rule, run the spiders twice as deep as the level of incorporation desired. GANG EXTENSION ATTACHMENT (Repair Parts Only) A gang extension attachment (Fig. 22) is used to extend the position of the rear gangs laterally. A gang extension attachment is required for each pair of gangs. The gang (806) 745-0384 Page 18 P/N L50012751 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 BIGHAM BROTHERS, INC. extension bracket is attached to the pivot clamp and rear gang as shown. The rear gangs and extension brackets are then adjusted to obtain the proper setting. ADD ON SPIDERS Optional add on spiders (Fig. 23) are available for the No. 1 and No. 2 rear gangs. The spiders are primarily used in conditions where spiders tend to clog. In this condition the scrapers are more effective if a spider is added on the right side of the No. 1 gang and the left side of the No. 2 gang. NOTE SWEEP SHANKS Sweep shanks (Fig. 24) are available to be used with the standard support bundles (Fig. 25). The sweep shanks are mounted on the end of the long pipes and centered between the rows. The sweeps are adjusted by raising or lowering the shank and tightening in place. When cultivator is fitted with appropriate sweeps, the sweeps will leave a slight furrow in the middle to help the driver guide the tractor accurately on the next cultivation. Sweep shanks also provide additional cultivation, especially when the rear gangs are set so that they do not overlap. Large sweeps may be used to keep water furrows open for flood irrigation practices. Threaded spider No. 1 should only be added to No. 1 gangs and threaded spider No. 2 should only be added to No. 2 gangs. NOTE Tighten spider to 220 ft./lbs. torque using piece of 1-1/2 inch pipe. Tighten jam nut to 220 ft./lbs. torque. (806) 745-0384 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 Page 19 P/N L50012751 BIGHAM BROTHERS, INC. A rigid shank (Figure 24, Item 1) is for use in clean soils. The trip foot shank (Item 2) is used in soils where rocks, stumps, etc., are present and some degree of protection is needed to prevent the sweeps from hanging on these obstacles. To adjust the trip foot shanks for more or less resistance and loosen for less. The spring shanks (Item 3) are used in conditions where maximum protection of sweeps from underground obstacles is desired. High speed sweeps (Item 4) are used for high speed operation where the sweeps slice through the soil without moving too much soil to each side. The high speed sweep is especially useful in narrow row spacing. BED RIPPERS Bed rippers with clamps are mounted to the tool bar and used to shave the top of heavily crusted, weedy beds during bed mulching operations. They can also be used in the tractor row middle to loosen heavy crust left by previous planting or cultivation. A variety of chisels or sweeps can be used on the bed ripper. The bed rippers are adjusted by raising or lowering the shanks and tightening in place. NOTE The tool bar has not been designed to use deep penetrating tools in each row. When the above tool is used in every row, the cable attachment must be used to prevent the tool bar from bending. (Fig. 53) TRIP FOOT BED RIPPER (Figure 26) Adjust the trip setting by applying only enough torque to keep the foot from tripping in clean soil. Applying too much torque to the trip bolt will not allow the foot to trip when an obstruction is encountered. (806) 745-0384 Page 20 P/N L50012751 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 BIGHAM BROTHERS, INC. COIL SPRING BED RIPPER (Figure 27) Coil shanks (Fig. 27) are recommended for use behind the tractor tires in rocky soils. The coil shank is mounted to the tool bar with the same clamp but the spacer (Fig. 27) is required in the clamp to allow interchangability of different bed ripper shanks. HEAVY DUTY CROP SHIELD The heavy duty crop shields (Fig. 28) are mounted directly to the pipe supports and adjusted for desired ground clearance. The heavy duty shields give more crop protection used as a crop shield, the adjustable panel is raised to its maximum height. DISC WEEDER A disc weeder (Fig. 30) is used over the row for more precise weed control than can be accomplished with the split row gangs. The disc weeder and clamp are usually mounted in front of the tool bar with the disc toward the front. It can be mounted behind the tool bar, with the disc to the front when front mounting interferes with the tractor. Install knives (not included) on the shanks behind the disc. Adjust the disc and the knives to the same depth or the disc may be run slightly deeper than the knife. Running the knife deeper than the disc has generally proven unsatisfactory. Angle the disc only enough to cut out an adequate groove for the knife. Run the vertical sides of the than the regular shields. DELUXE SHIELD HEAVY DUTY CROP The deluxe heavy duty crop shields mount to the rear pipe supports as shown in Fig. 29. Construction of these shields is much heavier than the regular crop shields, for heavy duty use in bushy crops. An adjustable panel at the bottom of the shield can be used for accurate control of dirt toward the crops. When (806) 745-0384 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 Page 21 P/N L50012751 BIGHAM BROTHERS, INC. knife in the deepest part of the groove cut by the disc. Run the disc about 1-1/2 inches deep. TWIN DISC ROW ATTACHMENT The twin row disc attachment (Fig. 31) is used to cultivate twin row patterns and can be adjusted to handle up to 14 inch spacing. The gauge wheel is mounted on the front bar of the frame so that the wheel is positioned to run between the twin rows. The discs are mounted on the first and second bar so they are staggered to reduce the possibility of stalks or other residue contacting both disc at the same time. Run the disc about 1-1/2 inches deep and slightly angled to cut out a groove for the knives that follow. Mount the hoe shank assemblies and knives (not furnished) on the second, third and fourth bars at the same depth as the disc or slightly shallower. Run the vertical side of the knife in the deepest part of the groove cut by the disc. The depth of the disc can be controlled by adjusting the gauge wheel. Adjust the downward pressure by moving the set collars on the rod for more or less pressure. (806) 745-0384 Page 22 P/N L50012751 705 E. Slaton Rd. TOOL BAR PIPE STANDS Pipe stands (Fig. 32) are available to support the cultivator when removed from the tractor. After hitching and lifting the cultivator, raise the pipe stand and pin in position. Two stands are required, one on each side of the tool bar. CAUTION DO NOT UNHITCH CULTIVATOR FROM TRACTOR UNTIL SUPPORTING STANDS ARE IN PLACE AND SECURED. PIPE STANDS ARE REQUIRED IF THE CULTIVATOR IS NOT EQUIPPED WITH GAUGE WHEELS OR FRONT MOUNTED COULTERS. P.O. Box 3338 Lubbock, TX 79452 BIGHAM BROTHERS, INC. CABLE ATTACHMENT When using bed rippers, trip shanks, coil springs or other deep penetrating tools in each row middle, a cable attachment must be used to prevent the tool bar from bending. To adjust the cable attachment see ASSEMBLY OF ATTACHMENTS. NOTE On some tractors the rear tires may prevent this attachment from being used without a cross bar being added across the front of the tractor. (806) 745-0384 705 E. Slaton Rd. P.O. Box 3338 Lubbock, TX 79452 Page 23 P/N L50012751 BIGHAM BROTHERS, INC. LUBRICATION MAINTENANCE CAUTION DO NOT PERMIT SMOKING, SPARKS OR AN OPEN FLAME WHERE COMBUSTIBLE LUBRICANTS OR LIQUIDS ARE BEING USED. CAUTION TO AVOID INJURY: DO NOT LUBRICATE, ADJUST OR REPAIR THE CULTIVATOR WHILE IT IS IN OPERATION. The cultivator requires very little lubrication. However, proper lubrication is essential. Below are the lubrication procedures and the intervals at which they should be performed. 1. Lubricate the grease fitting in the hinge pivots of the folding tool bar wing with a multi-purpose grease every 50 hours of operation. 2.Lubricate the fitting on the gauge wheel trunnion as needed. 3. Lubricate the four grease fittings in the twin row support with multi-purpose grease every 15 hours of operation. SEASONAL MAINTENANCE A little time and effort spent protecting the cultivator from destructive moisture will repay you in longer service, easier operation and higher resale value. Refer to the following information for maintenance at the end of the season. 1. Clean cultivator thoroughly to remove dirt and trash which could hold moisture and cause rusting. 2.Apply a good rust preventive to all land polished surfaces, such as sweeps and spiders. 3. Lubricate all fittings to fill cavities and thereby (806) 745-0384 Page 24 P/N L50012751 705 E. Slaton Rd. prevent moisture condensing in bearings.

DOUBLE DISC APPLICATORS — The double disc applicators and bracket mount to the 6400 series 7x7 tool bar. They are designed for conditions where a rigid fertilizer applicator would be damaged due to ground conditions. Double disc applicators may be used in pairs with a ‘Y” divider for banding on each side of the row or they may be used for banding on only one side of the row. (Figure R) SPOUT HOLDERS — The spout holders are designed to be used on the 6400 series rolling cultivator spider gangs when it is desirable to broadcast fertilizer along the row when cultivating the crop. Position the spout holder so fertilizer will be mixed with the soil uniformly when spiders pass over the fertilizer band. (Figure 5) (806) 745-0384 705 E. Slaton Rd. P.O.
