BELTS
Under tensioned V-belts can slip and squeal. This
generates excess heat and results in cracking and
premature belt failure. Over-tensioned belts reduce
belt and bearing life.
Properly tensioning and aligning a belt drive will allow
the belt drive to perform at it’s maximum level.
Stop the engine and remove the spark plug wire
before making any belt adjustments.
Adjust belt tension after the first five hours of
operation. Then tension as required.
BLADE BELT ADJUSTMENT
There should be a maximum of 1/2” deflection with 5
lbs pressure in the middle of the non idler side of the
belt.
1. Remove the four bolts E holding the Blade belt
cover G on. (Figure 1)
2. Loosen the bolt holding the small pulley C just
enough to move the pulley back and forth.
(Figure 2)
3.
Slide the small pulley firmly against the belt and
tighten bolt C . Check the tension and readjust if
necessary.
4. Replace the Blade belt cover G.
TRANSAXLE BELT ADJUSTMENT
The transaxle belt should have a deflection of 1/8” with
5 lbs. force.
1. Follow steps 1 & 2 in Blade Belt Adjustment
Section to loosen the blade belt so the transaxle
belt may be adjusted.
2. Loosen the two bolts B on each side of the
machine above the wheels. (Figure 3)
3. Use a pry bar in hook D behind the engine to
tension the transaxle pulley belt. (Figure 3)
4. While maintaining tension with the pry bar, tighten
bolts B .
5. Check the adjustment. Readjust if necessary.
6. Follow steps 3-4 in the Blade Belt Adjustment
section to re-tension the blade belt.
