ADJUSTMENTS
ADJUSTMENT OF BELT TENSIONER
There are four maximum belt tensioners on the Big Vac. Two control the
tension on the belts on the blower housing, one each on the finger reel
and the thatcher reel. The proper tension of the idler should be 12 to 15
as per the gauge (A) on the side of the tightener. Over tightening the belt
will shorten the life of the belt and the machine may not perform to the
best of its ability. To adjust belt tensioner, loosen bolt holding tensioner.
Bring idler pulley tight to belts and turn tensioner into belts to 15°. Tighten
holder bolt.

justment loosen the four adjustment
