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 mower deck belts are located under the rocker arms on each side of deck. To access each
belt, loosen the nuts and lift the rocker arm cover from the rocker frame.
The pulley idler belt tensioning system automatically tensions 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, damaged,
cracked, weathered, or otherwise appears to pose an unsuitable or unsafe operating condition,
replace the belt.
Check the belts for proper tension. If an idler tensioner reaches its maximum stroke without ade-
quately tightening the belt, you need to replace the belt. If the belt you are checking 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 5.14 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 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 equip-
ment, fire hazard, and projectile hazards.
Be sure to replace all covers and hardware.
