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

OPERATION
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.
• Always operate at full throttle speed.
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)
NOTE: In these instructions, “left” and “right” are
referred to as seen from the operating position.
WARNING
Read and obey all operation and warning decals.
WARNING

• Do not operate mower without the
complete catcher in place
• When operating on slopes, refer to
operator's manual for counterweights.
