3.13 Mower Deck Belts
WARNING!
NEVER inspect, adjust, or change the deck drive 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 pulley idler belt tensioning system located on decks 1, 3, and 5 automatically ten-
sions the belts on the mower decks, thus eliminating the need for manual belt tension
adjustment.
Check the belts for visible wear or damage. If any 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 belts for proper tension. If an 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. 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 each 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
properly tension the belt.
Clean each entire deck (including under the rocker arm covers) 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.
