"V" BELT DRIVE

"V" BELT TENSION - 100h / Monthly
Proper belt tension is a fundamental factor in successful V-belt
operation. Lack of tension will cause slippage, and too much
tension will cause excessive belt stretch as well as damage to the
drive components, such as bearings and shafts. To assess the
condition of the automatic tensioner, the following procedure is
recommended.
At the mid-point of the span (see illustration below), apply a
deflection force with a spring scale in the direction perpendicular to
the span until the belt is deflected the 3/8".
The recommended force to deflect the belt is a minimum of 5 lbs. to
a maximum of 7 lbs.
The first 24 to 48 hours of operation is the belt "run in" period. To
ensure satisfactory belt performance, belt tension should be
checked during this time period.
"V" BELT ADJUSTMENT
Each mower deck has (2) belts to transmit power from the gear box
to the blade spindles. Each drive belt utilizes an adjustable sliding
tensioner idler to set belt tension.
In the event that belt adjustment must be made, follow these steps
for each belt:
1) Loosen the jam nut on the adjusting screw.
2) Loosen the nut fixing the tensioning idler to the mower deck.
3) Set desired belt tension by turning the adjusting nut
