3.12 Deck Belt
Do not inspect, adjust, or change the deck belt while the engine is run-
ning.
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.
1. Access the belt by loosening the cover nuts and lifting the cover out from under the rocker
frame.
NOTE:
The pulley idler belt tensioning system automatically tensions
the belt on the mower decks, thus eliminating the need for manual belt
tension adjustment.
2. Check th
e belt for visible wear or damage.
If the belt appears excessively worn, damaged, cracked, weathered, or otherwise
appears to pose an unsuitable or unsafe operating condition, replace the belt.
3. Check the belt for proper tension.
If the idler tensioner reaches its maximum stroke without adequately 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 of this manual or contact your Lastec dealer for the proper belt lengths for
your Articulator.
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 Articulator.
4. Ensure 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 Articulator. This will help prevent damage to the
equipment, fire hazard, and projectile hazards.
