Handle adjustment knobs
Provides different handle heights for different
tilling conditions.
Loosen both handle adjustment knobs, and
pivot handle forward or backward to desired
height, then tighten the adjustment knobs
securely.
Depth regulator rod
Serves a dual purpose. It regulates the tilling
depth and helps the operator control the
direction and speed of the tiller.
For tilling, the transport wheel must be taken
out of its transport position by removing the
cotter pin.
Set the depth regulator rod with curve down to
the rear of the unit.
Lowering the depth regulator rod will slow the
tiller and make it till deeper. Raising the depth
regulator rod will allow it to move faster and till
more shallow.
To adjust the tilling depth.
1. Remove the cotter pin.
2. Raise or lower the depth regulator rod.
3. Align hole in depth regulator rod with the
holes in depth rod bracket and replace the
cotter pin.
Do not adjust tilling
depth unless tine clutch
control lever is released
to the neutral position.
For heavy soil (100mm / 4" depth or greater),
remove the depth regulator rod and work the
tines down with a back and forth motion to at
least a depth of 100mm (4"). Slowly pull the
tiller backward allowing the soil to feed forward
over the tines.
