Spring 2. Flat Washer 5. Hex Nut 3. Brake Rod To decrease brake force, refer to Figure 16 and proceed as follows: 1. Loosen the hex nut on the end of the brake rod under the spring as follows: remove the hairpin cotter and flat washer from the other end of the brake rod to disconnect it, and loosen the hex nut. NOTE At least 3 threads on the end of the brake rod must remain visible following this adjustment. 16 2. Reconnect the brake rod and secure it with flat washer and hairpin cotter. Recheck the adjustment making certain correct adjustment is reached before operating the tractor. If the tractor still cannot be pushed following this adjustment, and with the brake pedal lock released, see your authorized Cub Cadet Dealer. Measure the distances A and B on the front wheels. (Refer to Figure 18.) NOTE Dimension B should be approximately 1/8 inch less than dimension A. PIVOT BAR ADJUSTMENT BOLTS A CAUTION The tractor must be checked every 50 hours of tractor operation for play between the front axle and the pivot bar adjustment bolts. Both adjustment bolt heads must fit against the front axle. If play is discovered, the pivot bar adjustment bolts must be adjusted. If play is discovered between the front axle and the pivot bar adjustment bolt heads, adjust both bolts as follows: (Refer to Figure 17.) 1. Loosen jam nut 3 to 4 turns or as required. 2. Turn pivot bar adjustment bolt counterclockwise until it hits against the front axle. 3. Tighten jam nut. 4. Repeat the above steps for the other pivot bar adjustment bolt. WHEEL ALIGNMENT The front wheels should toe-in approximately 1/8 inch. (1/8" LESS THAN A) Figure 18 FRONT WHEEL ADJUSTMENTS To adjust the toe-in remove one ball joint, loosen lock nuts "C” at the ball joint and turn the tie rod ball joint in or out as required. (Refer to Figure 19.) NOTE Tie rod has a bend in the center for clearance of castle nut on pivot bar. Bend must remain.down as shown in Figure 19. Figure 17 1. Jam Nut 2. Pivot Bar Adjustment Bolts 3. Front Axle 17 TURNING RADIUS A CAUTION Be sure all parts are tightened after completing the following adjustment. The front wheels should have an equal angle for left and right turns. If adjustment is necessary, remove ball joint and loosen lock nut "D." (Refer to Figure 19.) Turn the drag link ball joint clockwise or counterclockwise as required. Figure 19 Tie Rod and Drag Link Ball Joints 1. Castle Nut at Pivot Bar 2. Bend in Tie Rod 3. Lock Nut "D" 4.

Keep clear of all moving parts and be careful of heated surfaces and mufflers. A WARNING To avoid injury or an accident, be sure the brake pedal is in the locked position, transmission is in neutral, and any equipment is disengaged before starting engine to make carburetor adjustments. A WARNING Carbon monoxide fumes can be fatal! Do not make any adjustments to the carburetor in a confined area such as a storage building. Move the tractor outside into the air. ■^NOTE Carburetor adjustments should be made only after the engine has warmed up. This engine is equipped with a fixed main jet carburetor. (Refer to Figure 20.) The carburetor is designed to deliver the correct fuel-to-air mixture to the engine under all operating conditions. The main fuel jet is calibrated at the factory and is not adjustable. The low idle fuel adjusting needle is also set at the factory and normally does not need adjustment. If, however, the engine is hard-starting or runs roughly or stalls at low idle speed, it may be necessary to adjust or service the carburetor. Turning the low idle adjusting needle in (clockwise) decreases the supply of fuel to the carburetor. This gives a leaner fuel-to-air mixture. Turning the adjusting needle out (counterclockwise) increases the supply of fuel to the carburetor. This gives a richer fuel-to-air mixture. Setting the needle midway between the lean and rich position will usually give the best results. NOTE Engines operating at altitudes above approximately 1829 m (6000 ft) may require a special "high altitude" main jet. LOW IDLE SPEED ADJUSTING SCREW Figure 20. Fixed Main Jet Carburetor 18 To Adjust Carburetor 1. With the engine stopped, turn the low idle fuel adjusting needle in (clockwise) until it bottoms lightly. The tip of the low idle fuel adjusting needle is tapered to critical dimensions. Damage to the needle and the seat in carburetor body will result if the needle is forced. 2. Preliminary Low Idle Fuel Needle Setting: Turn the adjusting needle out (counterclockwise) from lightly bottomed 1 full turn. 3. Start the engine and run at half throttle for five to ten minutes to warm up. The engine must be warm before making final settings (steps 4, 5, and 6). 4. Low Idle Speed Setting: Place the throttle control into the "idle" or "slow” po...
