SKID STEER TRENCHERS

CAUTION! When lowering a moving digging chain to the ground the force
of the teeth grabbing the ground will try to pull the trencher
suddenly forward.
Be prepared. Have the brake on the skid
steer set to help counteract the force.
Slowly lower the digging chain into the ground to start the trench.
Do this by lowering the trencher with the loader arms. Continue lowering
the unit until the crumber end rolls all the bay back on the crumber bar
(See Figure #7)
IMPORTANT: After the crumber end has rolled all the way back, do not
lower the trencher any farther without moving the skid steer in reverse.
Failure to do so could result in bending of the crumber boom, which is
not
covered by warranty.

Once the crumber end has "bottomed out", begin slowly creeping the
skid steer in
reverse while continuing to lower the loader arms. When near-
ing the required depth, stop lowering and tilt the trencher to a 60° to 65°
angle. A 60° - 65° angle works best for general trenching. (See Figure #8)
WARNING! Be alert to what is happening around you. Look behind you
before reversing the skid steer to trench. Be aware of any
person or thing in the path of the skid steer. Observe any
terrain changes such as drop-offs or soft ground.
