3.Insert the belt adjustment tool through the hole in the side of the adjustment block, spacing the ends of the tool equally on both sides. See Fig. 6-15. Rotate the tool so the slotted end faces down.

4.Place the Wheels/Tines/PTO Drive Lever in FORWARD position. The arms of the clutch control yoke will be resting on the belt adjustment tool and the clutch roller should be engaged slightly beneath the adjustment block. See Fig.

6-16.

5.Use one hand to hold the drive lever in FORWARD while using a 9⁄16” wrench to loosen — don’t remove — the bolt at the back of the belt adjustment block. See Fig. 6-17. The adjustment block should be free to move either up or down.

6.Push the drive lever down if the belt needs tightening. Pull the lever up if the belt needs to be loosened. Hold the drive lever in place and tighten the bolt in the adjustment block firmly.

7.Let go of the drive lever and remove the belt adjustment tool from the hole in the adjustment block.

8.Check the tension on the belt by following the previous instructions “How to Measure Belt Tension.”

NOTE: If the adjustment block is all the way down and the measurement between the clutch roller and the bracket is less than 1⁄4”, then a new drive belt is needed.

Reverse Drive System

These instructions explain how to inspect and adjust the various reverse drive components.

But first, here’s how the reverse drive system works. When you raise the Wheels/Tines/PTO Drive Lever up in REVERSE position, this lowers the rubberized reverse disc — it’s attached to the engine drive pulley — until this rotating disc contacts the transmission drive pulley. The friction between the rotating reverse disc and the transmission pulley causes the transmission drive shaft to be powered in a counterclockwise direction — as viewed from the operator’s position behind handlebars. The drive shaft then turns the wheels and tine shafts in a reverse direction.

The reverse disc is made of steel with a special, long-lasting rubber compound bonded to the disc rim. Since this is a wearing part, it should be inspected after every 30 operating hours.
