Operation With Turbo
• Grass should be cut often but not too short. If grass is
too long or lush, it may be necessary to keep ground
speed to a minimum or to cut only half the width to
prevent clogging. If grass is too high, operate with
mower in high cutting position. Cut the grass again in
lower cutting position, if desired.
• Before mowing, clear the lawn of all sticks, stones,
wire and other debris which may be caught or thrown
by the mower blades.
• The blower housing should be removed for cleaning.
If a large amount of cut grass is spilling out from
under the deck, the tube may be plugged or grass
bags are full. Shut off tractor, disengage the PTO,
remove the key, and allow all moving parts to stop
before disconnecting the tube.
● For added tractor stability and to prevent tipping or
loss of control:
a. Use reduced speed on uneven ground and when
turning corners.
b. Reduce loads on hillsides. It is recommended that
the collection system be kept only half full when
negotiating any slopes. Start mowing on slopes
when the collection system is empty.
c. Mow up and down the face of slopes; never
across the face of any slope.
• Always operate at full throttle speed.
● When operating on slopes, use front counterweight.
Never operate on slopes greater than 17.6% (10°).
● Know the tractor controls and how to stop quickly.
READ THE TRACTOR OPERATOR’S MANUAL.
● Disengage the electric clutch (PTO). Shut off the
engine, remove the key, and wait for all moving parts
to stop before attaching, adjusting, or disconnecting
any part of the collection system.
● Check the collection system to make sure it is bolted
tightly to the tractor.
● Look behind to make sure the area is clear before
backing up.
Operation Without Turbo
• For operation without the turbo, the deflector must be
properly installed in the down position and retained
by the spring latch.
• To remove turbo, reverse the installation steps.
Recommended Accessories
• Front counterweight is recommended when using
rear-mounted grass catcher.
• On slopes over 17.6% (10°), use two rear wheel
weights in addition to front counterweight.
Always mow up and down the face of slopes, never across
the face. Never mow on slopes greater than 30% (16.7
degrees)
● DO NOT turn sharply when travelling alongside a
building or any object.
● DO NOT carry passengers on the tractor.
● Read and obey all warning decals.
NOTE: In these instructions, “left” and “right” are
referred to as seen from the operating position.
