HP Owner’s Manual
PROPULSION
This unit is self-propelled, and is controlled by an operator presence control. To
engage the wheel drive, lift the operator's DRIVE lever on the right side against
operator's handle. The drive is disengaged by releasing the lever. (See figure 16-
6).
GROUND SPEED can be varied by selecting a higher or lower gear using the
gearshift lever on the frame (see figure 16-7). Note: Only change gear selection
when unit is stopped. Under most conditions cutting should be done in second or
third gear. The quality of the cut produced is directly related to the unit's ground
speed during cutting. If the quality of the cut is not satisfactory (i.e. material left
standing), you should shift into a lower gear during cutting.
HILLSIDE MOWING
WARNING! Never mow on any slope greater than 15 degrees. Always
mow across the face of slopes; never up and down or diagonally (see figure
16-8). DO NOT attempt sudden starts or stop when mowing on a slope.
Avoid sudden turns and use extreme caution when changing direction on a
slope.
BLADE CLUTCH
The HP mower blade clutch is controlled by an operator presence control. To
engage the blade, depress the operator’s left hand control lever against
operator’s handle. The blades are disengaged by releasing this lever. (See figure
16-5)
NOTE: The blade clutch must be either fully engaged for cutting or fully
disengaged to bring the blades to a stop. Do not operate the unit with the blade
clutch partially engaged. Premature belt wear and clutch failure will result from
improper operation of the clutch.
CAUTION: Use extreme care when operating the blades. Inspect the work
area for foreign objects that could cause damage to the unit or injure the operator
if struck by the blade. Never operate the blades with bystanders in the work area.
Never operate the blade without either the discharge deflector chute or the grass
catcher in place.
