TRACTOR HIGH SPEED TRACKING

If the tractor tracks to one side with both drive control levers fully forward, adjust the control levers as follows:

Check for proper and balanced air pressure in both front and rear tires. Refill tires if necessary.

Perform the first three steps in the previous sub- section, Tractor Creeping, to verify that the tractor is not creeping. If creeping, adjust following the instructions in that sub-section.

Recheck the tracking after making any adjust- ments to the transmission control rods.

If uneven tracking persists, note which direction the tractor is tracking.

-If the tractor tracks to the right, adjust the control lever stop bolt on the left side.

-If the tractor tracks to the left, adjust the control lever stop bolt on the right side.

Locate the applicable stop bolt on the left or right console. See Figure 27.

Loosen the jam nut on the stop bolt, then turn the stop bolt counterclockwise to make it longer. Recheck the tracking and fine tune the adjust- ment as necessary.

NOTE: If the stop bolt is adjusted too far, the tracking problem will change sides. Make fine tuning adjustments by shortening the same bolt.

Tighten the jam nut against the console and repo- sition the control lever if necessary.

TRANSMISSION DRIVE BELT

If the transmission drive belt becomes worn and causes the drive transmissions to slip, the drive belt must be replaced. To replace the drive belt, proceed as follows:

Remove the deck drive belt from the PTO clutch on the bottom of the engine following the instruc- tions in Deck Removal, SECTION 5: MOWER DECK.

From beneath the rear of the tractor, insert a 3/8 inch drive ratchet into the square hole of the drive idler bracket. See Figure 28.

Using the ratchet for leverage, pivot the idler bracket and idler pulley away from the backside of the ‘V" belt; then lift the belt off and above the engine pulley and off the idler pulley.

With the belt loose, lift the belt off, up and over the two transmission drive pulleys. Remove the belt from the engine and idler pulleys.

Loop the new belt and slide over and onto the two transmission pulleys.

Route the belt above the idler bracket back to the engine drive pulley. Lift the belt over the PTO pul- ley and above the engine drive pulley.

Using the ratchet for leverage, pivot the idler bracket and idler pulley against the spring ten- sion; then slip the belt down into the engine drive pulley and onto the idler pulley.

Release the idler bracket so that the idler pulley tightens against the back side of the belt and ten- sions the drive belt.

Reinstall the deck drive belt.
