Landmark Tractors Old vs New Process of Evolution John Deere’s M-Tractor design is 20-years old, yet the steel chassis and modular component design that was first used on the original 6000 Series remains the backbone of the latest generation of the company’s tractors. We brought together a John Deere 6400 and a brand new 6125R to find out what has changed and how the old and new models compare. Words by Simon Henley; pictures Jonathan Page. L AUNCHED IN 1992, the John Deere 6400 was the largest four-cylinder model in the 6000 Series. The brand new model offered outstanding in-field performance and was an instant success with farmers across Europe. Along with its smaller 6000 Series siblings, it represented one of the greatest innovations in modern tractor design. That was 20 years ago, however, so how well does it compare with what John Deere offers today? The 2012 John Deere 6125R is one of nine new tractors in the latest 6R range that represents the fourth generation of 6000 Series development. The 6R Series is made up of five four-cylinder models spanning 105hp to 140hp and four six-cylinder machines from 150hp to 210hp. The 6125R, which is powered by the latest Stage IIIB version of John Deere's well proven 4.5-litre engine, offers 125hp (max 138hp) and a host of transmission options, including Deere's new DirectDrive twin-clutch transmission, in addition to front linkage and PTO options. Yet while dramatically different in terms of specification and appearance, the 6125R Series retains the same highstrength steel backbone chassis design and is still built using modular components. The basic layout of the 6125R is also similar to the old 6400. For example, the cab position in relation to the chassis is the same, the fuel tank location is the same and even the battery compartment is where it used to be. The rear axle and hydraulics, although much improved, are very familiar in appearance, and although slightly larger, the tractor itself has that distinctive feel that can only be associated with a John Deere. Arguably, the biggest difference between these tractors lies in the technology that’s used to control their functions and the way they are operated. When the 6000 Series was introduced, its new optional Headland Management system was considered Main Picture: David Musson’s immaculate 1994 John Deere 6400 (100hp) goes head to head with one of its modern-day successors, the 6125R (125hp/max 138hp). The 6125R sits in the middle of Deere’s new five-model range of four-cylinder 6R Series tractors. state-of-the-art. Whereas many of the 6400's primary functions were still mechanical, today the 6125R utilises a computer to control the engine and transmission, and satellite technology to guide it across the fields. Despite its age, when you swing open the cab door of the 6400 the operator station, or TechCenter, as John Deere called it, the interior still has a surprisingly pleasant feel. The seating position is excellent and with some minor adjustment the operator is soon very comfortable. Just like the 6R Series tractors of today, the instrument panel tilts with the steering wheel and visibility from the driver’s seat is exceptionally good. To the driver’s right, the control console houses the hand throttle, the forward/reverse shuttle, the four-speed powershift lever and the gated rangechange lever. Further along the console sit the auxilliary hydraulic levers, the rear linkage controls and the PTO levers, while a raised control panel displays numerous warning lights and houses the tractor’s ventilation controls. Jump in the new 6125R’s redesigned ComfortView cab and immediately it feels much roomier, yet at the same time also quite familiar. Despite the fact that the control console has a bewildering number of buttons, the layout is surprisingly similar to the 6400. The main gear lever, for example, features buttons for declutching and operating the four powershift speeds, yet the basic range shift pattern of the AutoQuad Plus transmission remains just like the old PowerQuad gearbox found in the 6400. But it’s here in the cab where computer technology takes over. The 6R tractor’s built-in Above: The TechCenter cab fitted to the 6000 Series was a massive departure from the SG2 unit it replaced. It had two doors, more space, completely new controls and lower noise levels. Above Right: The interior of the latest ComfortView cab feels familiar but there’s a lot more gadgetry and buttons. Thanks to the front axle and cab suspension, the overall ride is much smoother. Command Centre unit can be used to electronically set transmission shift points and control individual oil flow rates to the auxilliary hydraulics at the touch of a button. It also allows the use of new technologies such as Isobus and GreenStar satellite navigation without the need for rewiring the tractor. One of the best things about the new 6R Series, from a driver’s perspective at least, is the ride comfort. With just 72dB(A) at the driver’s ear, fully floating cab suspension and triple-link front-axle suspension, comparing the 6125R to the 6400 is like comparing a Rolls-Royce to a Vauxhall Vectra. Driving them both across the field, the difference in ride quality is quite remarkable. It’s hard to believe they are both based on the same type of modular chassis, but they are, and that’s where the suspension has made such a difference.

Rory Day reports. F ARMING 310 ACRES with his father, William, at South Loftus, near Saltburn-onSea, Farm View contributor Paul Stevenson has fond memories of International Harvester tractors that go back to him sitting on a ‘Snoopy’ at the Yorkshire Show when he was just eight years old. The feeling has endured and he has owned a Case-IH 1255XL since 2003 and a Case-IH MX135 since 2004. After buying the Case-IH 1255XL, however, he decided what he really wanted was an Americanbuilt IH. This would only be to play with, rather than to put to work, and he considered something like a two-wheel drive IH 1466 from the early 1970s would be ideal. Last year, however, Paul ended up buying a larger and more recent IH 5288 that was built in the first half of the 1980s. In fact, it was a tractor that he knew well as it had been operated by neighbouring farmers C., K. & D. Muir Ltd for the past 20 years. “I’d never thought about owning it,” says Paul, “although I once told Richard Muir that I’d like a US-built IH and he kept on at me to buy his. I think he wanted to still be able to see it in the area. “What changed my mind was when our 1255XL started having trouble lifting the 4m combination drill when it was full near the end of last summer; that’s when I decided to buy it.” Carrying the serial number 6012, the tractor is one of 1280 IH 5288s built by the company during 1984 and probably came off the production line in the late summer or early autumn. After writing about the machine in his Farm View column in the November 2011 issue of CLASSIC TRACTOR, Paul found out a lot more about its history. Above: Cleveland farmer Paul Stevenson has been fascinated by IH tractors since he was a child. Now he’s living the dream with probably the best IH 5288 in the country. Above Right: This is how C344 CRH looked when it arrived last year. It was down at heel, having previously spent several years outside powering a slurry stirrer on a local farm. Inset Right: The cab was in a dreadful state. The mudguards were beyond repair, the roof panel was rotten and there were holes in the bottom of both doors and many other areas. Main Picture: Paul Stevenson’s fully refurbished 1984 IH 5288 gleaming in the sun and looking back to its very best at Saltburn-on-Sea in Cleveland. “I was contacted by Ian Scruton of Wilfred Scruton Ltd, who sold the tractor when it was new,” he says. “They bought the tractor from IH in February 1985 and sold it to Martin Simpson of Seamer near Scarborough the following October. They then took the tractor back in as a part exchange in 1990 and that’s when it was then sold to the Muirs.” Paul also spoke to Mr Simpson, who told him that he used it on a seven-furrow semi-mounted reversible plough with a press. Once it moved to the Muirs, the tractor was hitched up to a 4m power harrow/drill combination and carried out that task for 10 years, during which time it was also fitted with a front linkage. In 2002, however, the purchase of a Case-IH Magnum saw the 5288 downgraded to slurry tanker duties for a few years, while since 2008 it had been used solely on the slurry stirrer. Potash mine “Unfortunately the tractor was standing outside all the time it was on the slurry stirrer, and this, combined with the fact that the Boulby potash mine is nearby, took its toll on the cab,” notes Paul. After picking up the 5288 in late August last year Paul put it to work on a five-leg subsoiler working 16in deep. “It performed well, even though the spines were shot in the four-wheel drive front coupler so it was only working in two-wheel drive,” he says. “What this did show me, however, was that the tractor was basically sound.” It also showed up a few other issues that would have to be dealt with: there was oil leaking out of the steering orbital valve and some of it was running down the back of the dashboard; while it was also having a few fuel problems. “I took the rear filter off and found it full of grey/blue sludge,” Paul says. “This was because the fuel tank was missing its cap and rags and obviously blue tissue paper had been used over the tank filler.” Work to strip the tractor down started in October. “The cab roof was full of holes, one mudguard was home-made and the other was rotten and smashed up,” he says. “All the rotten bits that couldn't be removed from the cab area were cut out and replaced with new steel. This was mainly in 8 CLASSIC TRACTOR August 2012 the areas below the side windows and in the inside of the rear cab pillars, but a lot of the top front windscreen frame also had to be cut out and new metal welded in. “The cab interior was also gutted, and the steering orbital valve seals were replaced. Both halfshaft seals were changed, and I also fitted a new four-wheel drive front coupler,” he adds. Another serious mechanical job was dismantling the PTO. “The brake wasn't working and I was going to fit three new brake pads, but when I took it apart I found that the front bearing was on its way out and the teeth on the clutch pack were worn,” says Paul. “A phone call to my local Case IH dealer, Paxtons at Northallerton, gave me a nice surprise as the clutch pack was only £84 when I was thinking that it would be in the hundreds. I also replaced all the bearings while I was in there. Phil and Tim in Paxtons’ stores have really been a great help.” Meanwhile the main bonnet panels, which were in pretty good shape, were rubbed down and primed. Some warmer weather just before Christmas also allowed him to get the chassis painted, although the preparation required a lot of elbow grease. “Mike Links of Triple R Tractors of Illinois restores 88 Series tractors and he recommended that I didn’t shotblast the chassis because it gets into places where it shouldn't,” says Paul. With the chassis painted in IH Gloss Black, which Paul feels is more like a satin black, the project was really progressing. Right from the start Paul knew that he would have to get parts sent from the United States as the panels are no longer available from Case IH dealers. August 2012 CLASSIC TRACTOR 9 one of Howard’s doors and cut large rotten pieces out of my doors and welded in replacement parts from the old Snoopy doors.” Right on cue, the first parcel from the United States arrived and as well as a full cab interior, it included weld-on door bottom skins. These were welded on the day they arrived and a tiny amount of filler was used to smooth the joins. “This is the only filler used on the entire tractor,” notes Paul. The new Western-style cab interior was fitted and the wiring was checked over. A Bluetooth CD player was installed, while new sidelights and mirrors from Tractor Parts UK finished off the cab. Next the main bonnet panels were glossed and the decals were applied. The tractor had come with a set of dual wheels for the front and rear, so these were painted using the Case IH silver. “They are Terry Johnson wheels and I was short of a set of weld-on cleats for one wheel,” recalls Paul. “Philip Lake, our local representative for New Holland dealer Russell’s of Malton, managed to identify them and get me some new cleats. I also needed some replacement front tyres and ended up buying some good part-worn Goodyears from Cornthwaite Tractors of Lancashire.” While Paul was waiting for his second shipment Owners’ register Paul Stevenson’s IH 5288 rebuild project has prompted him to start an owners’ register for 1980s International 5288 and 5488 tractors based in the UK and Ireland. A total of 5905 IH 5288s and 3951 IH 5488s were built at the company’s Rock Island plant in Illinois, but Paul’s research suggests that not many more than 50 were imported for the UK and Irish market. “I currently know of about 20 tractors that are still running,” he says. “So far, mine is the latest serial number I’ve come across, although I know there was at least one more sold after it. Thankfully the article in CLASSIC TRACTOR resulted in a call from Howard Sherren who put him in touch with Ken Updike of the Wisconsin-based Carter & Gruenewald Company which has been able to source most of his requirements. The roof proved to be a bit harder to find, but one was eventually found on a 3788 in a breaker’s yard by Mike Links. “I ordered a load of parts from Ken Updike,” recalls Paul. “The first items came by airmail, while the larger parts – including the full roof and mudguards from Triple R Tractors – came by boat.” Other help came from Andrew Brown of Suffolk who runs a host of IH tractors including a 5288 and the first 5488 imported from the United States. Andrew proved extremely useful with advice and supplying part numbers for many items, as well as identifying the lights, mirrors and so on that would have been fitted by IH in the UK as part of the homologation process that was required to meet UK road legislation. One thing that couldn't be supplied by the Carter & Gruenewald Company were the UK market spacers that fit between the mudguards and the cab. Fortunately, one of the existing spacers was good enough to use as a template and Rob from Agri Plus Ltd of Stokesley, North Yorkshire was able to make replacements. Agri Plus also helped Paul extract some broken exhaust manifold bolts and while the manifold was off, the rocker cover gasket was replaced and the tappets adjusted. “One very strange coincidence happened one day after I’d been on the phone to Rob,” says Paul. “Shortly after he rang back and said that a man 10 CLASSIC TRACTOR August 2012 who’d been in his workshop said that he had the original front linkage for the 5288 that the Muirs had sold a few years ago. I bought it and Rob then got some side plates made to fasten the linkage onto the side chassis rails for extra strength.” When the engine was all back together, it was time to hitch the tractor to Rob’s dynamometer. “It put out 175hp on the PTO and would sit all day running at 170hp,” says Paul. “This means it must be close to 200hp at the engine, which is good considering it hasn't been tweaked at the pump and hasn’t done any hard work for years.” Close match Next on the agenda was painting the wheels. When new, the rims were painted IH Aluminium, but as this is no longer available, Case IH silver, which is a close match, was used instead. “I also discovered that some of these tractors get repainted the wrong colour,” notes Paul. “I found out that the red that should be used is exactly the same as the old Magnum red, so I duly ordered some enamel from Paxtons. I had thought about two-pack paint, but decided to go with the correct enamel as that’s what it would have had when it was new.” Paul then turned his attention to the doors and this turned out to be a job that was a real pain. “I visited Howard Sherren in October last year and came home with the old doors off an IH Snoopy that he restored several years earlier,” he says. “I replaced the whole left window frame with one off Paul would like to hear from anyone who has one of these tractors and he can be contacted on 07778 806743 or by email at pstevenson01@btinternet.com Above: The chrome stack isn’t an original fitment, but it looks great!

Friday 13 April certainly wasn't unlucky for Paul as that’s the day his crate of parts arrived from the United States.

Next the front cab pillar covers were fitted, although with the UK additions of mirrors and sidelights, this was a bit of a fiddly job. Part of the difficulty was because the left-hand mirror needed setting a bit differently to accommodate one of two non-standard alterations Paul has carried out. Final stages “I decided to fit an American modification to the gas strut on the left door,” he says. “It opens the door wider and much more easily than the bent metal rail that was fitted as standard, and it also prevents the door getting blown onto your leg if you are getting in on a windy day.” One of the last jobs to get done was refitting the long bonnet. “This was one of the final stages in the transformation,” says Paul. “Putting it on again after it had been off for seven months was an important milestone, and it also made the tractor look much taller.” Next the chrome exhaust was put on the tractor. This was the other non-standard part that was fitted and was made by the firm that supplies Kenwood trucks. “I have seen photos of tractors in the United States fitted with these and I think they look good,” says Paul. “Also, the last 5488 to roll off the production line at Rock Island was fitted with one, as were the 7288 and 7488 Snoopys.” The finishing touch was some red trim to go around the top edge of the cab. Once again, Andrew Brown came to the rescue giving Paul contact details for Key Restoration Services of Selby which was able to supply exactly what he needed. “All in all, I’m very pleased with how my 5288 has turned out,” says Paul. “Apart from help with the exhaust manifold studs, front-linkage brackets and regassing the air-con I can say I did it all myself. “I’m really looking forward to putting the duals on and hitching it up to my 4m Dowdeswell HD power harrow with Kuhn Maxi packer and Accord drill,” he adds. “It’s a lovely quiet cab and very American with the Western leather-look interior. I might even get a Stetson but one thing’s for sure, I won't be listening to Kenny Rogers – it’s more likely to be Iron Maiden and Motorhead!” Ultimate Barn Finds Incredibly original MASSEY FERGUSON 135 Tucked away in a private collection in Nottinghamshire is a Massey Ferguson 135 QD that has done just five hours from new in 1977. Totally original in every possible way, it is the ultimate time-warp tractor. Simon Henley carefully examines this priceless machine and describes its features; with pictures by Rory Day. A S FAR AS BARN FINDS GO, this MF 135 QD must be one of the most exceptional tractors CLASSIC TRACTOR has encountered for a number of years. Yet this tractor very nearly ended up being used on a set of gang mowers when its current owner Eric Elliot purchased it for his Nottinghamshire estate 10-12 years ago. Thankfully, on the advice of his good friend and fellow tractor collector Richard Fenton, the tractor, serial number 473415, never went to work and remains in as-new condition, having never turned a wheel in anger during its 34-year life. “When Richard told me I shouldn't use the tractor I was quite surprised,” says Eric, who also owns an exceptional collection of mainly vintage-era tractors. At the time he says he placed very little value on the MF 135. “In truth, 10 or 12 years ago I didn't consider this tractor would be worth anything in the future, or that it may be the only one left in this sort of condition.” There’s no doubt this tractor is a valuable collector’s item, but there’s far more to this tractor than its considerable value. It is like an Egyptian mummy – a beautifully preserved example of the past and an unmolested treasure that remains almost exactly the same now as it did when it rolled off the production line at Banner Lane. It is a rare opportunity to see exactly what an MF 135 looked like when new in 1977. Before we delve into the specific details surrounding this particular tractor, it would be prudent to first discuss some of the history behind the MF 135 QD. It was, after all, a bit of an odd-job tractor in 1977, the MF 135 itself having fundamentally been replaced on the UK market by the higher-spec MF 550. The problem was that in 1976, when Q-cab legislation came into force, a number of tractor operators were suddenly flummoxed by the new structures, simply because the new low-noise cabs couldn't be removed or folded like a safety frame to enter low buildings. Massey Ferguson was the first manufacturer to respond to this issue by fitting a QD (Quick-Detach) January 2012 CLASSIC TRACTOR 13 Above: Eric Elliot purchased his MF 135 to put on a gang mower but was persuaded not to use it by a friend. He is currently deliberating whether to sell his extensive tractor collection by auction in early 2012. If this happens, the MF 135 will be included in the sale. Above Right: Even the cab door latches and door handles still have their original coating of factory MF red paint protecting them. That’s how little use this MF 135 has seen. A serial number of 473415 dates this MF 135 QD to 1977, probably the middle of the year. When new, it would have had a list price of £5117 and a net price of several hundred less. Below Left: Contents of the time-warp toolbox include the original tax disc holder, as supplied by Chandlers of Grantham, plus Category II ball ends for the arms and top link.

It does, however, match up on the opposite side. 36 CLASSIC TRACTOR January 2012 cab to the 135, which was still in production at Banner Lane, specifically for a number of export markets. MF, in conjunction with Cab Craft, developed a cab for the 135 that not only met the sub-90dBA noise criteria, but could also be split at fender level to allow access into traditional low buildings. Inside the cab, the familiar MF 135 controls remained the same but with the addition of rubber matting on the floor and gearbox and thick rubber mouldings around the dash console to suppress the noise. Additionally, a padded roof and wheel arches helped to insulate the driver from engine noise. The history behind this six-speed tractor is quite remarkable. It was one of several MF 135 QDs purchased in the late 1970s from MF dealer Chandlers at Grantham in Lincolnshire by a local machinery dealer. The dealer seemingly had a sizeable amount of spare money to invest and acquired a number of these machines, along with several Fords, then put them away in one of his buildings purely with the intention of selling them at a future date. More than 20 years later at least one, and possibly more, of the MF 135 QDs were put on the market and sold. One of them, the tractor shown here, found its way to Eric Elliot in Nottinghamshire. It has barely turned a wheel since and is in remarkably original condition. The head lining in the cab roof is unmarked and the door latches still have red paint on them. Virtually every safety and warning decal is present and intact, and the Right: Original factory-fitted 12.4/11 x 28 Goodyear Traction Sure Grip rear tyres, distinguished by the diamond shapes on the tyre walls, are in brand new, unused condition.

Inside the toolbox the original factory-supplied Category II balls for the link arm ends are like new and the Category II top link end is still in its factory wrapping. The original lynch pins are still in place on the link arms, while the QD cab’s two-piece flexible rear curtain, which has had the benefit of being rolled down to fender level, is in great shape. It's a similar story mechanically. Pull the dipstick from the three-cylinder Perkins AD3.152 engine and the oil is crystal clear. This isn’t surprising because it has only ever been circulated a handful of times, the last time probably more than 30 years ago. Closer examination of the tractor reveals some interesting little points and clues to how these tractors were put together. During 1977 the Banner Lane plant, in common with the rest of British industry, was suffering from cutbacks, industrial unrest and regular strike action by the trade unions. As such, the tractors that were being built sometimes lacked the precise fit and finish that was a feature of earlier machines. For example, purists might note that the silver ‘Massey-Ferguson’ decal running down the nearside of the bonnet falls short of the circular ‘135’ medallion at the front by almost half-an-inch, leaving an area of red paint uncovered. The wiring for the light on the number plate bracket is also untidy, with hastily added connections that have been left exposed to the elements and potential damage, while there is also a small area of what appears to be grey paint, possibly primer, on the lower, offside edge of the tractor’s bright red bonnet. The question as to whether this type of workmanship was commonplace during the late 1970s is best answered by someone who actually worked at the Massey Ferguson factory at the time. Enter Harold Pritchett of Mancetter, north “ “It looks like the grey paint on the bonnet could have been a post-production issue,” says Harold, examining photographs of the tractor closely. “Panels with marks like this rarely ever got through inspection, so I am going to suggest that the overspray or brush mark was done by the delivering dealer during a PDI. If a minor correction had to be made pre-delivery, the dealer might well have touched up the grey engine paint, possibly even with a brush. The other key consideration is that the factory never used paint brushes and this certainly looks like a brush mark. “With regards to the silver bonnet decal, faults like this were down to individuals,” he adds. “There As far as barn finds go, this MF 135 QD must be one of the most exceptional tractors CLASSIC TRACTOR has encountered for a number of years Warwickshire, a former quality inspector for Massey Ferguson who worked at Banner Lane for 27 years, commencing in 1967.

Left: QD (Quick-Detach) versions of the MF 135 had a detachable cab designed in collaboration with Cab Craft. The cab detached at fender height and was held in place by eight bolts. Bottom Left: The linkage has never been used. Note the ‘workmanlike’ wiring for the number plate light and also how the insulated cab floor matting simply hangs over the rear axle. Bottom Right: The dashboard, which is covered with thick rubber sound insulation, is untouched and provides a brilliant point of reference for would-be MF 135 QD rebuilders. notes that the plastic tag hanging behind the fuel pump should have been removed and was most likely an ID tag with a part number for the fuel line. This part could have been fitted post-assembly, having failed inspection at either the Banner Lane factory or possibly when it reached the supplying dealer. “By the late 1970s MF was starting to cut manufacturing costs,” continues Harold. “They were buying components and materials from cheaper suppliers. Evidence of cutting corners can be seen by 38 CLASSIC TRACTOR January 2012 the rusty cab mounts. This is a result of using cheaper grades of paint that have deteriorated and corroded over the years.” “It should be remembered that we weren't building Rolls-Royce cars,” he adds. “Tractor assembly, particularly on the Banner Lane tracks, wasn't an easy or gentle process. Tractors were pushed and pulled to get them together and as long as everything fitted to a reasonable standard and worked, it was considered satisfactory.” It might have a misplaced decal and a small dab of grey paint on the bonnet, but there can be no denying that this 1977 Massey Ferguson 135 QD is still a very, very special tractor, one that probably just about every MF enthusiast would like to call their own. It is also totally authentic and a truly unique piece of MF tractor history.
