2. Hydrostatic Drive
Neutral Adjustment
The drive itself contains no adjustments.
The ground control lever, when in
automatic neutral position, should not
allow any forward or rearward creeping
of the grinder (providing the grinder is
on level ground – on unlevel ground,
see brake control instructions).
Neutral position is adjusted by
removing the quick disconnect from
the control arm, located on the
bottom side of the transmission.
Turn the "Quick Disconnect" socket
one (1) complete turn in either forward
of the reverse position to adjust
transmission into neutral (more than one
turn may be needed in some cases).
Disengagement Adjustment
When the engine is not running, the grinder cannot be moved; the hydrostatic drive is in the
"locked" position.
Turn T-handle clockwise to unlock the transmission.
This will allow freewheeling / manual movement of the stump grinder.
3. Electric Clutch Engagement
The electric clutch needs no adjustments or lubrication.
CAUTION
1.
Never engage clutch over 1,800 RPM (1/2 throttle).
Any clutch engagement over 1,800 RPM can and will
damage the clutch.
2.
Make sure that there is a minimum of 12 volts to the
clutch at all times. The torque arm on the clutch must
move freely at all times from 1/8" up and down, and
from side to side. You can visually inspect the torque
arm through the square hold located in the backside of
the belt guard.
DANGER:
Never transport the stump grinder with the clutch engaged or cutter wheel rotating.
