WARNING: Look to the rear before
backing up.
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.
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.

optional equipment for lawn tractors with 38" and
42" decks. Grass Collector Model 190-103-000 is
