Extending PTO Drive Belt Life
The PTO drive belt will provide a long service life if
properly installed and operated. Check the following to
help extend belt life.
Maintain correct belt tension.
Maintain correct mower level.
Maintain correct blade slope in transport.
Adjust the position of the mower belt guide.
Replace damaged pulleys.
Always operate engine-powered attachments at full
throttle.
Avoid engaging the PTO when the mower is in tall
uncut grass or weeds.
Cut tall grass and weeds with the mower in its highest
position, making a second pass cutting at desired height.
Regularly clean the mower of any buildup of grass
clippings.
Use low range or reduce ground speed when mowing in
heavy conditions or when mulching or bagging.

Washing the Mower
After each use, wash the underside of the mower to prevent
grass build-up and improve performance.
1. Park the tractor on a hard level surface.
2. Apply the parking brake, start the tractor, and raise the
attachment lift.
3. Get off the tractor. Place the mower height-of-cut lever
in the lowest cut position.
4. Lower the attachment lift, stop the engine, and remove
the ignition key.
5. Attach a hose coupling to the end of the washout fitting
and turn water on high (Fig. 36).
Note: Spread petroleum jelly on the washout fitting o-ring
to help the coupling slide on easier and protect the o-ring.
