Figure 5. Belt Installation

Proper Twist: The belt then follows with a 3/4 twist back under the left V-idler, up over the drive sheave and back down under the right idler pulley. This will leave a 1/4 twist in the section of belt extending from the right V-idler to lower groove of the center mower sheave. If not installed correctly, more twist will result than is allowable.

Adjust the mower to proper cutting height. The front of the mower should be slightly lower than the rear for the best cutting and least power requirement.

Idler Adjustment: Make minor belt adjustment with idlers but keep left idler about 1" above being in line with the groove in which the belt runs on the center sheave of the mower and right idler about 1" below. Move mower fore and aft for major adjustments.

Belt Troubleshooting

Belt Whip

Belt whip is caused by belt misalignment unless mower is driven by a rough-running or 2-cylinder engine. On certain models a belt guide is provided to dampen out the whip on the loose side. The guide should be set to just clear the belt in normal position.

Proper Position of 59

Adjust mower forward and back to such a position that the rear take-up idlers are near the bottom of their slots when the belt lines up with the proper groove in the center pulley and is tight. Never run the idlers high in the slots as this will cause misalignment.

It is assumed that the mower is adjusted to run approx- imately level. If the front of the mower is down, the idlers will have to be raised. If the back of the mower is down, the idlers will have to be down further. Belts must be in proper alignment with sheave grooves as shown in Figure 6 through Figure 8.

PTO Pulleys

PTO Pulleys must be moved in or out to cause the belt to be in alignment with the idlers.

Belt Tension

Run belts very tight. Slipping will heat and ruin a belt but tension is not harmful.

How to Align a Twisted Belt

Right: Inside edges of the belt are approximately lined up with the sheave.
