Deck Leveling, Cutting Deck Engagement

•Depress the clutch-brake pedal until the scissor brackets come together.

•Shut off the engine.

•Tighten hex nut on the scissor mounting bracket.

•Thread the speed selector rod in or out of the ferrule until the hydrostatic control lever lines up in neutral position on the speed control index bracket.

•Tighten hex jam nut against the ferrule.

•Replace the transmission panel, parking brake knob and rubber boot on relief valve.

•Remove the blocks from under the frame and test the operation of the tractor.

Deck Leveling

If the tractor is cutting grass unevenly, level the deck following instructions on page 10.

Cutting Deck Engagement

The cutting deck engagement may be adjusted to ensure that deck is disengaged when lift lever is in BLADES STOP position. Correct adjustment as follows.

•With the engine off, place the lift lever in the highest cutting position (first position).

•Remove the cotter pin and flat washer which secure the disengagement rod to the stabilizer shaft assembly. See Figure 14 .

•Shorten the rod by threading it in, until the ferrule is against the back of the slot in the lift shaft assembly, and the rod lines up with the hole in the stabilizer shaft.

•For more belt tension, the disengagement rod must be lengthened. To decrease belt tension the disengagement rod must be shortened.

•Check the adjustment by placing the lift lever in the BLADES STOP position. The deck should move up and forward, allowing the belt to become loose.

Start and test for disengagement. Repeat procedure as necessary.

Brake Adjustment

WARNING: Do not have the engine running when you adjust the brake.

The brake is located by the right rear wheel inside the frame. The brake has been set at the factory to the proper clearance. During normal operation of this machine, the brakes are subject to wear and will require periodic examination and adjustment.

•To adjust the brake, adjust the nut so the brake starts to engage when the brake lever is 1/4" to 5/16" away from the axle housing. See Figure 15 .

Wheel Adjustment

(Units with Adjustable Tie Rod)

The caster (forward slant of the king pin) and the camber (tilt of the wheels out at the top) require no adjustment. Automotive steering principles have been used to determine the caster and camber on the tractor. The front wheels should toe-in between 1/16- 5/16 inch. To adjust the toe-in, follow these steps.

•Remove the hex nut and the lock washer, and drop the end of the tie rod from the axle bracket. See Figure 16 .

•Loosen the hex jam nut on tie rod.
