"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, 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
All deck drive belts utilize a threaded adjuster connected through
the deck gear box mount. Tension of both drive belts per deck is
set with one adjustment.
In the event that belt adjustment must be made, follow these steps:
1) Loosen the jam nut on the adjusting screw.
2) Loosen the (4) bolts fastening the gear box to the mower
deck.
3) Set desired belt tension by turning the adjusting screw
