To stop the lawn tractor, pull the hydrostatic control
lever into NEUTRAL (N) or depress the clutch-brake
pedal.
Be sure that the lawn is clear of stones, sticks, wire,
or other objects which could damage lawn tractor or
engine. For best results and to insure more even grass
distribution, do not mow when lawn is excessively wet.
A WARNING: Before leaving the operator's
position for any reason, disengage the
blades, place the hydrostatic control lever
in neutral, engage the parking brake, shut
engine off and remove the key.
When stopping the unit to empty a grass bag, etc.,
follow the instructions above. This procedure will also
eliminate "browning" the grass, which is caused by hot
exhaust gases from a running engine.
GRASS COLLECTOR AVAILABLE
Grass Collector Model 190063 is available as optional
equipment for the lawn tractors shown in this manual.
A WARNING: The mower should not be
operated without the entire grass catcher
or chute deflector in place.
NOTE: Under normal usage bag material is subject to
wear, and should be checked periodically. Be sure any
replacement bag complies with the mower manufac-
turer's recommendations. For replacement bags, use
only factory authorized replacement bag.

6. Start the engine. Make certain the clutch-brake
pedal is depressed and the parking brake is set.

tapping screws on the bottom of the seat. See figure
1. Slide the seat forward or backward as desired.
Retighten the self-tapping screws.
HYDROSTATIC CONTROL ADJUSTMENT
The hydrostatic transmission control is in correct ad-
justment when the lawn tractor does not move with the
engine running, the clutch engaged and the hydrostatic
control lever in the neutral (N) position.
If adjustment is necessary, follow these steps.
NOTE: A rachet wrench with a 112" socket extension
is required to make this adjustment.
1. Remove the transmission panel by removing the
parking brake knob and truss machine screws.
Loosen the bolt and nut on the bracket on the
hydrostatic control lever. See figure 13.
WARNING: Be careful of the cooling fan on
the hydrostatic transmission.
