3.11 Deck Belt
Warning
WARNING!
NEVER inspect, adjust, or change the deck belt while the engine is running!
ALWAYS clean the entire deck area (under the operator seat pan) of all grease, oil,
fuel, grass, or debris to prevent fire and projectile hazards!
The mower deck belt is located under the rocker arms on each side of deck. To access
the belt, loosen the nuts and lift the cover out from under the rocker frame.
The pulley idler belt tensioning system automatically tensions the belt on the mower
decks, thus eliminating the need for manual belt tension adjustment.
Check the belt for visible wear or damage. If the belt appears excessively worn, dam-
aged, cracked, weathered, or otherwise appears to pose an unsuitable or unsafe operat-
ing condition, replace the belt.
Check the belt for proper tension. If the idler tensioner reaches its maximum stroke with-
out adequately tightening the belt, you need to replace the belt. If the belt you are check-
ing is new, and the idler tensioner slides to its maximum stroke without adequately
tightening the belt, it is likely you have installed the wrong size belt. See section 5 of this
manual or contact your Lastec dealer for the proper belt lengths for your Lastec Mower.
If you are unable to install a new belt with the idler system at its minimum stroke, it is likely
you are installing the wrong size belt. Contact your Lastec dealer for proper belt lengths
for your Lastec Mower.
Be sure that the idler pulley tensioning spring is properly installed and in good condition. If
for some reason this spring becomes loose, detached, or fatigued, the idler will not prop-
erly tension the belt.
Clean each entire deck (including under the rocker arms) of all excess grease, oil, fuel,
grass, or debris before operating your Lastec Mower. This will help prevent damage to the
equipment, fire hazard, and projectile hazards.
Be sure to replace all covers and hardware.
