Digging a Trench
In general, the process is the following:
1. Assemble the mini-trencher and mount it
on the cart.
2. Get the mini-trencher into position over
It takes a little practice to get proficient with the
mini-trencher. Read on for a few tips and strate-
gies for success.
the area you want to dig, and strap on the
belt.
3. Start the engine (we use the trigger on the
power head to get it started, then adjust the
tension on the throttle cable as needed),
and then move up to the throttle-extension
arm [6C] to power the engine.
4. Get the chain rotating at a moderate speed
(50-75%) before you bring it into contact
with the ground. Too high a speed risks
throwing projectiles and too low can cause
a stall.
5. Work the nose of the mini-trencher into the
ground to desired depth, up to 90 degrees.
The angle of the digging chain determines
the depth of trench.
Before beginning, strap on belt to avoid
entanglement.
6. Adjust the pivot arm as needed. We recom-
mend holding the rear handle of the power
head when adjusting.
7. Use the belt to pull the weight of the tren-
cher towards you, in the direction you want
to dig the trench.
8. Use a rocking motion to get to get past
compacted soil and minor obstacles.
9. If you strike large rocks, thick tree roots,
Never operate on the downhill side of the
machine!
• If operating on a slope, operator should stay
on the uphill-side of the machine.
Adjusting the cart arm
The cart arm (throttle-extension/pivot arm) allows
you to exert downward pressure on the nose of the
mini-trencher and control depth. Adjust it as needed.
1. Hold the rear handle of the power head, de-
press the clevis pin [15C] inward to disen-
gage from the pivot plate [14C], and pivot
the throttle-extension arm up or down.
2. Once adjusted, release inward pressure to
re-engage the pivot plate.
