???When operating on slopes, refer to operator's manual for counterweights.
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
???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)
