"V" BELT DRIVE

"V" BELT TENSION:
Proper belt tensioning is a fundamental factor in the 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. Therefore, to ensure proper belt tension, the following procedure is recommended.
"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 slide plate to the
mower deck.
3) Set desired belt tension by turning the adjusting screw:
Clock Wise to tighten belts

4) Tighten the (4) bolts fastening the gear box slide plate to the
mower deck.
5) Tighten jam nut on the adjusting screw.
6) Verify proper tension is achieved per "V" Belt Tension section
above.
CHECKING BELT TENSION
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 4.9 lbs. to a maximum of 7.3 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.
