NOTICE
Do not make sharp turns or large steering
corrections while trenching. This will swing

Digging efficiency is determined by a combination of
boom position, soil conditions, obstacles in the ground,
and condition of the digging teeth.
Boom Position
For best digging performance and smoothest tractor
operation, trencher must be in full down digging position
with lift cylinders in float position.
Move tractor forward to simply pull digging teeth into the
face of the trench.

Obstacles In Ground
F
•
Loose, wet soil conditions will require a faster chain
speed than hard, dry soil conditions. Adjust ground speed
as necessary to maintain adequate chain speed for the
specific soil conditions.
Decrease ground speed and make steering
changes in very small increments.
To cut a sharp curve, use either of the following
methods:
•
If material is flexible enough for a sharp 90°
corner, cut a new trench 90° to previous trench.
•
If material is not flexible enough for a sharp
corner, use a backhoe to open up corner (G) to
allow for a more gradual bend.
Be alert for potential contact with obstacles while digging
that may cause damage to the machine or injury to a field
worker.
Digging chain is generally able to cut through wood and
small debris. Digging efficiency is reduced by contact
with any unseen obstacles.
If an obstruction stops digging chain causing PTO
clutches to slip:
1. Immediately stop forward travel and disengage PTO.
Do not raise trencher from digging position unless
absolutely necessary.
2. Slowly move tractor rearward until free of obstruction.
3. Apply parking brake, stop engine and remove ignition
key.
4. Place a “Do Not Operate” tag on tractor ignition
switch.
5. Inspect digging path to determine the obstruction.
G
If obstruction is wood or other soft debris, verify chain
is snug against the chain box and proceed forward
slowly.
If obstruction is steel, concrete, or rock, remove
obstruction before proceeding.
