Transporting the Trencher on
a Trailer

Place the trencher on a trailer or truck capable of
carrying it. Securely tie the trencher to the trailer or
truck using tie straps appropriate for the weight of the
trencher and for highway use.

Operating Tips

Clean the area of trash, branches and rocks before
trenching to prevent equipment damage.

Always begin trenching with the slowest ground
speed possible. Increase speed if conditions permit.

Always use full throttle (maximum engine speed)
when trenching.

Always trench backwards (i.e., in reverse).

Never transport the trencher with the loader arms
raised. Keep the arms lowered and the trencher
tilted up.

When trenching, the spoils auger should just clear
the original ground surface to obtain maximum soil
removal.

Trench at a 45 to 60 degree angle for best results.

You will be able to dig a trench faster by controlling
the depth with periodic adjustments of the loader
arms.

If your traction unit has a speed selector (present
on some wheeled traction units), set it to the slow
(turtle position).

If your traction unit has a flow divider (present
on some wheeled traction units), adjust it to
approximately the 10 o’clock position.

If the trencher binds in the soil, push the auxiliary
hydraulics lever fully forward to reverse the chain
direction. Once the chain is loose, pull the lever
rearward again and continue trenching.

If you need the finished trench to be cleaner than
what is possible with the trencher, you can purchase
a crumber from your dealer. The crumber mounts
onto the trencher and scrapes the trench clean as
you run the trencher.

To improve the quality of trenches less than 24
inches (61 cm) deep, use a 24 inch (61 cm) boom
on the trencher.
