Whenever impeller belt is adjusted it is necessary to
readjust jackshaft belt (engine drive) or chain (PTO
drive).
Jackshaft Belt
1.
Check tension by depressing belt at mid span of
jackshaft and clutch pulleys with 4 to 5 lbs. of force.
Belt should deflect .25 in. If deflection is incorrect,
proceed to next step. If correct, continue operation.
2.
To adjust belt tension:
•
Remove (4) capscrews, washers and nuts securing
upper shroud to frame (Fig. 25).
•
If belt has too much slack, loosen idler pulley nut, press
forward on idler pulley until desired tension is obtained
and retighten idler pulley nut.
•
If belt is too tight, loosen idler pulley nut, pull rearward
on idler pulley until desired tension is obtained and
retighten idler pulley nut.
Reel Drive Belt
1.
Check tension by depressing belt at mid span of idler
pulley and reel driver pulley with 25–29 lbs. of force.
Belt should deflect .25 in. If deflection is incorrect,
proceed to next step. If correct, continue operation.
2.
To adjust belt tension:
•
Remove (2) capscrews, nut, retaining nut and washer
securing lower belt guard to frame (Fig. 28). Remove
guard.

•
If belt has too much slack, loosen idler pulley nut
(Fig. 29), press down on idler pulley until desired
tension is obtained and retighten idler pulley nut.
•
If belt is too tight, loosen idler pulley nut (Fig. 29), pull
upward on idler pulley until desired tension is obtained
and retighten idler pulley nut.
