MOWER SERVICE & ADJUSTMENTS"
Keep the topside of the mower freeof grass cuttings.
Buildup of clippings could cause belt problems and also
might present potential fire hazard especially when dryl
If uneven cutting is noted, check the tire pressure first
as this is the most common cause. If tire pressure is
correct and uneven cutting persists, move the tractor
to a flat level surface, such as a garage floor, and check
the deck level. (See "LEVELING MOWER", Page 13).
To prolong the life and efficiency of your mower, keep
the underside of deck clean and free of accumulated
grass clippings by washing it down with a hose and/or
scraping with awire brush and scraper. Make sure this
is done at the end of the cutting season before placing
the mower in storage.
