Adjusting Belts

Ensure that the belts are properly tensioned to ensure
proper operation of the machine and unnecessary wear.
Check belts frequently.
Adjusting the Reel Drive Belt
Check the tension by pressing the belt at mid span of the
pulleys with 3 to 5 lb. of force. The belt should deflect 1/4
in. (0.63 cm). If the deflection is incorrect, adjust the belt as
follows:
1. Remove the belt cover mounting screws and the belt
cover (Fig. 35).

2. Loosen the idler pulley mounting nut and pivot the idler
pulley clockwise against the backside of the belt until
you attain the desired belt tension.
Important
Do not over tension the belt.
3. Tighten the nut to lock the adjustment.
4. Install the belt cover by placing it in position.
5. While maintaining a slight gap between the cover seal
and the side plate, install each mounting bolt until the
threads engage in the insert. The gap allows visual
alignment of the bolts to the threaded inserts.
6. After all bolts are installed, tighten them until the
stand-offs inside the cover contact the side plate. Do not
overtighten.
