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. Adjust the castle nut so the brake starts to engage when the brake lever is 1/4" to 5/16" away from the axle housing. NOTE: Figure 6 is shown with the unit tipped up on rear wheels for clarity only. Brake Lever Axle Housing Castle Nut Cotter Pin 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. 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. Replace the tie rod into the wheel bracket, and replace the cotter pin and flat washer. DECK ADJUSTMENT (Model 800) The deck adjustments which follow are for the 30" deck only. For 32" or 38" decks, refer to the next section. 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. A deck adjustment rod is located on the right side of the unit. See figure 9. To adjust the deck, loosen the two hex nuts at the right rear deck link assembly. Thread the hex nuts up or down the deck adjustment rod as necessary. Retighten the hex nuts. FIGURE 9.—Model 8CI0 Front to Rear Adjustment The front of the deck should be approximately 1/4" to 3/8" lower than the rear of the deck. Adjust the pitch as follows. 1. Place the deck in the engaged position. 2. Remove the hairpin cotter and flat washer which hold the deck lift connecting rod to the front deck lift assembly. See figure 10. 3. Remove the connecting rod from the deck lift assembly and thread it in or out of the ferrule as necessary. See figure 10. Replace the rod. 9 FIGURE 10.—Model 800 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 12. 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. DECK ADJUSTMENT (Models 1002 and 1208) 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 11. 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 deck as described in step 2, and readjust if necessary. Tighten the hex nut to secure the adjusting screw when the deck is level. \ \ Adjusting /Screw Hex Nut '' FIGURE 11.—Models 1002 and 1208 Hairpin Clip BLADE BRAKE ADJUSTMENT (Model 800 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 13. 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. 10 End of Brake Cable FIGURE 13.—Model 800 Only 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 14. Slide the seat to desired position and retighten the selftapping screws. STEERING WHEEL ADJUSTMENT There are three height positions for the steering wheel. See figure ...
