During normal operation of this machine, the brake is subject to wear and will require periodic examination and adjustment. To adjust the brake, remove the cotter pin (if so equipped). Adjust the nut so the brake starts to engage when the brake lever is 1/4” to 5/16” away from the axle housing. Reinstall the cotter pin (if one was removed). NOTE: Figure 6 is shown with the unit tipped up on rear wheels for clarity only. FIGURE 6. WHEEL ALIGNMENT 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 mower. The front wheels should toe-in 1/8 inch. See figure 7. To adjust, follow these steps: 1. Remove the cotter pin and flat washer which hold the tie rod to the axle bracket. See figure 7. 2. Adjust the tie rod in or out until the wheels toe-in approximately 1/8" (Dimension “A” should be approximately 1/8" less than dimension “B”). See figure 8. 3. Replace the tie red into the wheel bracket, and replace the cotter pin and flat washer. FIGURE 8. DECK ADJUSTMENT Side to Side Leveling NOTE: Check tire pressure in all four tires before leveling the deck. Recommended tire pressure is 12 p.s.i. If an uneven cut is obtained, the deck may be leveled. 1. Raise the deck to its highest position. 2. With the unit on a hard, level surface, measure the distance from the bottom edge of both the left rear and right rear of deck to the ground. 3. If adjustment is needed, loosen the hex nut on the adjusting screw, located under the right side of the frame. See figure 9. Move the adjusting screw inward to lower the right side of the deck, or outward to raise the right side of the deck. 4. Remeasure the desck as described in step 2, and readjust if necessary. Tighten the hex nut to secure the adjusting screw when the deck is level. 9 Front to Rear Adjustment To obtain the best cut, the front of the deck should be between 1/4" and 3/8" lower than the rear of the deck. 1. Make the side to side adjustment as instructed previously. 2. Measure the distance from the bottom edge of the front and right rear of deck to the ground. 3. If the front is not between 1/4" and 3/8“ lower than the rear, remove the hairpin clips and flat washers which secure the J-bolts to the front of the deck, both right and left sides. See figure 10. Thread the J-bolts into or out of the ferrules as necessary. 4. Reassemble J-bolts and recheck the adjustment. Readjust as necessary. Secure with flat washers and hairpin clips when adjustment is correct. Hairpin Clip BLADE BRAKE ADJUSTMENT (Model 1030 Only) A WARNING: Make certain spark plug wire is disconnected and grounded against the engine while making this adjustment. To adjust the blade brake, proceed as follows. See figure 11. 1. Disconnect the brake cable from the lower inside belt guard on the lawn tractor by removing the hairpin cotter, flat washer and clevis pin. 2. Lower the deck to its lowest position. Place the blade engagement lever in the disengaged position. 3. Pull the brake cable back so there is no slack in the cable. Do not put tension on the cable. Select the hole in the lower inside belt guard which aligns with the end of the cable. Move the end of the brake cable forward to the next hole in the belt guard (which will give a small amount of slack in the cable), and reassemble. SEAT ADJUSTMENT The seat may be adjusted to different positions. To adjust the seat, loosen the four self-tapping screws which secure the seat to the seat bracket. See figure 12. Slide the seat to desired position and retighten the self-tapping screws. STEERING WHEEL ADJUSTMENT There are three height positions for the steering wheel. See figure 13. To adjust, proceed as follows. Remove the steering cover by removing four self-tapping screws. Remove the hex bolt and hex lock nut on the steering shaft. Raise or lower the steering shaft to desired height. Secure with the hex bolt and hex lock nut. Reassemble the steering cover. 10 Steering Shaft FIGURE 13. CARBURETOR ADJUSTMENT A WARNING: If any adjustments are made to the engine while the engine is running (e.g. carburetor), disengage all clutches and blades. Keep clear of all moving parts. Be careful of heated surfaces and muffler. Minor carburetor adjustment may be required to compensate for differences in fuel, temperature, altitude and load. To adjust the carburetor, refer to the separate engine manual packed with your unit. NOTE: A dirty air cleaner will cause an engine to run rough. Be certain air cleaner is clean and attached to the carburetor before adjusting carburetor. A LUBRICATION WARNING: Always stop engine and disconnect spark plug wire before cleaning, lubricating or doing any kind of work on riding mower. Engine—Maintain the engine oil according to the engine manual. Front Wheels—Front wheels which have bronze bearings are provided with grease fittings. L...
