OF USE TO PROLONG THE LIFE OF BELTS. Check brake puck Check parking brake Check tire pressure NOTE: infl ate to mfr.’s specifi cation as shown on tire side-wall Part No. 520141 Form No. F061604A 17.1 CABLE ADJUSTMENTS Brake Adjustment The brake control cable is spring loaded and requires no adjustment; however, the transaxle brake is adjustable. When the mower is in neutral and can be pushed by hand without depressing the brake lever, the transaxle brake needs adjustment. Using a . inch wrench turn the adjusting nut . turn clockwise (see fi gure 17-1). With the machine in neutral and: 1. The brake lever not depressed, the brake should be on and inhibit the machine from being rolled by pushing. 2. The brake lever depressed the brake should be off and the machine should roll uninhibited by the brake. Transaxle Drive Control Cable Adjustment When the transaxle drive belt slips, the drive control cable needs to be adjusted or the belt needs to be replaced with a new belt. Cable Adjustment: 1. Using a 3/8” wrench, remove the rear access door (Item 51). 2. Using a . “ open end wrench, turn the inside adjusting screw clockwise 1/8 of a turn and then tighten the outboard adjusting nut against the support bracket (see fi gure 17-2). 3. Check for proper operation. If the operation is not correct, repeat step 2. 4. Replace the access door. The drive control cable adjustment should be the minimum amount required so the belt does not slip when the drive is engaged. CAUTION: DO NOT make cable adjustment when engine is running. Disconnect spark plug wire before making any adjustments. Page 11 of 20 17 MAINTENANCE continued Blade Drive Control Cable Adjustment When the blade drive control lever is depressed, the blades should turn and the blade drive belt should not slip. When the cable is properly adjusted the tension spring on the end of the control cable will open slightly (only enough for a piece of paper to slip between the coils). See fi gure 17-3. Cable Adjustment: 1. Remove the deck belt cover (Item 81). 2. Observe the tension spring on the end of the cable when the blade drive lever is depressed. The spring should just break open. 3. If adjustment is required, using a .” open end wrench, turn the inboard adjustment nut clockwise 1/8 of a turn (Figure 4). Then tighten the outboard adjustment nut against the cable support bracket (Item 49). 4. Check the spring tension with the blade drive lever depressed. 5. Readjust the control cable as needed for proper tension. 6. Replace the deck belt cover. Note: Too much tension will shorten belt and bearing life and too little tension will allow the belt to slip.

A properly balanced blade will increase life of the bearings and other components. Tools required: ratchet, 3/4” inch socket, torque wrench, adequate support, block to inhibit blade rotation. 1. Disconnect spark plug wire. 2. Support front of unit to allow access to the blades. Note: Unit is heavy. Be sure support is adequate to prevent personal injury. 3. Block the blade to prevent it from rotating during removal (see fi gure 17-4). For Each Spindle: 4. Remove the blade bolt (Item 35), lock washer (33), and large friction washer (103). 5. Remove the blade (18) and replace or sharpen the blade. NOTE: Use only B.G.I. Part no. 520001(Standard blade) or B.G.I. Part no. 520002 ( Mulch blade). 6. Reinstall the blade using all fasteners in the exact order they were removed (see fi gure 17-4). 7. Torque blade screw to 60 ft-lbs. NOTE: Before installing the fasteners inspect them for wear and replace as necessary. 8. Reconnect spark plug wire. When replacing one belt the other should be inspected for wear and replaced if worn. It is good practice to change both belts when either is worn beyond use. Use only original equipment belts for replacement. Billy Goat uses only premium quality, kevlar corded and coated belts in your unit. Substitute belts do not meet the design and performance requirements for your unit , and will greatly reduce machine performance and belt life. 17.5 BELT REPLACEMENT 17 MAINTENANCE continued Figure 17-6 Figure 17-4 Blade Drive Belt Replacement Tools required: ratchet, 3/4 inch socket, 10” extension bar for socket, two .” wrenches and adequate support for machine. 1. Disconnect spark plug wire. 2. Remove the deck belt cover. 3. Support front of unit to allow access to underside of the machine near the engine. Note: Unit is heavy. Be sure support is adequate to prevent personal injury. 4. Observe the orientation of the belt fi ngers (Item 71) under the engine. 5. Remove the 4 engine mount bolts (Item 48) 6. Remove the left and right belt...
