Tensioning Drive Belts

The rotor shaft is driven from the gear motor via “V” belts which are adjustable for tension. After stopping the
tractor engine, remove the drive guards to tighten the belts. Check the tension by applying a force of 6.17 -
7.72 lbs at right angles to the belt in the centre of the two pulleys. If the deflection is great than 1/4” then
release the motor mounting plate screws and adjuster locknut and screw the adjuster to tighten the belts until
the deflection is 1/4”. Then, tighten the locknut, recheck the belt tension, and replace the belt cover.

IMPORTANT: Do not overtighten belt as this may cause premature failure of the rotor shaft and motor

bearings.
