3.6 Deck Belts
WARNING!
NEVER inspect, adjust, or change the deck drive belts while the tractor is running.
Always clean the entire deck (including under the belt covers) of all grease, oil, fuel,
grass or debris to prevent fire or projectile hazards.
CAUTION!
When cutting with new belts, do not over-power the Articulator within the first few
hours of operation. Listen for excessive belt slippage Check belt tension after 2
hours of operation. Check all belt tension adjustment hardware after the first 8 hours
of operation.
The deck belts are located under the belt covers on each deck. To access the belts,
remove the cover mounting hardware, and remove the belt cover from the mower deck.
The spring-loaded idlers automatically tension the belts on the mower decks, thus elimi-
nating 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 pivots to 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 pivots 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 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.
Be sure that each idler pulley tensioning spring is properly installed and in good condition.
If for some reason a spring becomes loose, detached, or fatigued, the idler will not prop-
erly tension the belt.
Be sure to replace all belt covers. Reattach and tighten all fasteners.
