IMPORTANT:
engine. Remove wire from spark plug, thoroughly
inspect the unit for any damage, and repair the damage
before restarting and operating the mower.
NOTE: If any problems are encountered, refer to the
Trouble Shooting Guide.

SETTING THE CUTTING HEIGHT

Select the position for the tractor lift lever which gives
the desired cutting height. Then move the wheels on
the deck so that the wheels are 1/4 to 1/2 inch above
the ground.
NOTE: To obtain the best, uniform cut, the deck is
designed to be suspended from the tractor at the
desired cutting height. The deck wheels or deck roller
should be just off the ground, to smooth out the cut and
guard against gouging.

OPERATING THE TRACTOR

• Start the engine as instructed previously.
• Move throttle control to full throttle to prevent strain
on the engine and to operate attachments.
• Place the shift lever in one of the two forward
positions (LOW or HIGH), or in REVERSE. Place
the speed control lever in desired position. Use first
speed position when operating the tractor for the
first time.
WARNING: Look to the rear before
backing up.
• Release the parking brake by depressing the
clutch-brake pedal. Release clutch-brake pedal
slowly to put unit into motion.
• The tractor is brought to a stop by depressing the
clutch-brake pedal.
• The cutting blades (or other attachment) may be
engaged while the tractor is moving or standing still.
DO NOT engage the cutting blades abruptly as the
sudden belt tension on the pulley may cause the
engine to stall.
WARNING: Keep feet and hands away
from the discharge opening, the blades or
any part of the deck.
NOTE: When operating the unit initially, there will be
little difference between the highest two speeds until
after the belts have seated themselves into the pulleys
during the break-in period. Be certain to change oil in
the crankcase after the first 5 hours of operation.
Be sure that the lawn is clear of stones, sticks, wire, or
other objects which could damage 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 shift 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.
If unit stalls with speed control in sixth or seventh
speed, or if unit will not operate with speed control lever
in first or second speed position, proceed as follows.
Place shift lever in NEUTRAL.
Restart engine.
Place speed control lever in highest speed position.
Release clutch-brake pedal fully.
Depress clutch-brake pedal.
Place speed control lever in desired position.
Place shift lever in one of the forward positions (HIGH
or LOW) or REVERSE, and follow normal operating
procedures.
HIGH-LOW TRANSMISSION RANGES
HIGH range position is for normal load conditions, such
as mowing or transporting.
LOW range position is for situations which require more
torque when the tractor is used under high load
conditions, such as tilling, snow removal or hauling
heavy loads.
GRASS COLLECTOR AVAILABLE
GRASS COLLECTOR Model OEM-190-083 is
available as optional equipment for tractors with 46"
mowing decks.
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 to
use only factory authorized replacement bag.
