SECTION 8: ADJUSTMENTS Land Pride! WARNING Unless specifically required, DO NOT have engine running when servicing or making adjustments to the mower. Place control levers in the park position, set the park lever to (ON) and remove ignition switch key. Repairs or maintenance requiring engine power should be performed by trained personnel only. To prevent carbon monoxide poisoning, be sure proper ventilation is available when engine must be operated in an enclosed area. Read and observe safety warnings in front of manual. Your Razor was adjusted before it left the factory and was checked during pre-delivery set-up. However, after start-up and continued use, a certain amount of break-in wear will cause some adjustments to change. Remain alert for unusual noises, they could be signaling a problem. Visually inspect the machine for any abnormal wear or damage. A good time to detect potential problems is while performing scheduled maintenance service. Correcting the problem as quickly as possible is the best insurance.! WARNING Keep your machine clean. Remove heavy trash deposits and clippings from the machine. Keep all moving parts, hydraulic system, engine cooling system and exhaust system clean of trash and clippings. Accumulation of trash and/or clippings can cause fires, hydraulic overheating and excessive belt wear. Clear away heavy build-up of grease, oil and dirt, especially in the area of oil, fuel and engine combustion air; minute dust particles are abrasive to close-tolerance engine and hydraulic assemblies. Some repairs require the assistance of a trained service mechanic and should not be attempted by unskilled personnel. Consult your Land Pride service center when assistance is needed. TORQUE VALUES! WARNING Particular attention must be given to tightening the drive wheel lug nuts and blade spindle bolts. Failure to correctly torque these items may result in the loss of a wheel or blade, which can cause serious damage or personal injury. It is recommended that the following be checked after the first 2 hours of initial operation, and every 50 hours following removal for repair or replacement: Wheel lug nuts Wheel motor nuts Blade bolts For engine torque values, see engine owner s manual.

Land Pride SECTION 8: ADJUSTMENTS CONTROL LEVER NEURAL ADJUSTMENT Before considering any adjustment, check tire air pressure and make certain hydraulic oil is at operating temperature. Unequal tire pressure will cause mower to drift to one side. Refer to Tire Inflation Chart on page 63 and page 63. Adjustments for neutral position is made to the pump linkage rods located between the control lever and pump arms. The pump linkage rods are properly adjusted when control levers are in neutral position and drive wheels are not turning. Refer to Figure 3-2: If the mower creeps in neutral position, adjust pump linkage rods, located under the seat, as follows: 1. Raise and block mower up to support drive wheels off the floor.! WARNING Make certain mower is secure when it is raised and placed on the jack stands. The jack stands should not allow the mower to move when the engine is running and the drive wheels are rotating. Use only certified jack stands. 2. Position control levers in neutral position and disengage blades. 3. Start engine and observe which way the wheels are rotating. Jam Nut Pump Linkage Rod 5. If wheel is rotating in reverse: a. Loosen jam nuts on pump linkage rod. b. Rotate rod to shorten steering control linkage until the wheel comes to a stop. c. Repeat for the opposite side if necessary. d. When both wheels remain in neutral, tighten jam nuts to lock the pump linkage rod(s) in place. 6. Test again by moving control levers forward and backward before returning them to neutral position. The unit is ready for operation if the tires do not rotate with the control levers in neutral. 7. Turn ignition switch off, place control levers in park and set park lever to (ON). Remove support blocking and safely lower mower wheels to the floor. STEERING DAMPER Refer to VFigure 3-3: The steering dampeners, located under the seat, are incorporated into the unit to provide some resistance when control levers are moving forward or rearward. Make sure steering dampeners are adjusted properly by moving control levers to the reverse position and releasing them. If control levers return to neutral position, they are working correctly. Adjust control levers if they do not return to neutral. Adjusted as follows: 1. Place control lever in neutral position. 2. Adjust left dampener rod: a. Loosen nut on the left front ball stud. b. Pull dampener spring housing, to the rear, past the point that the internal spring is engaged. c. Release dampener spring housing and allow the internal spring to bring the housing back to neutral position. d. Retighten left front ball stud nut.

When both wheels remain in neutral, tighten jam nuts to lock pump linkage rod(s) in place. 20684 Dampener Spring Housing Steering Dampener Figure 3-3 9/24/09 Z44 and Z52 Accu-Z Razor (S/N 472620 and above) Riding Mowers 357-044SM 65
SECTION 8: ADJUSTMENTS Land Pride 3. Repeat step 2 to adjust the right dampener rod. 4. Check steering dampeners: a. Move the control levers to reverse position and release. The control levers should return to neutral position. b. Repeat steps 1 through 4 if control levers do not return to neutral position. NOTE: The dampener must not bottom out when the pump lever is fully stroked in either direction. SEAT ADJUSTMENT IMPORTANT: The arm rests on the Deluxe Seat must be pivoted up before hinging the seat platform forward. Leaving the arm rests down while hinging the seat platform forward can cut the arm rest covers and void their warranty. The seat platform is slotted so the seat can be adjusted to the operator. Loosen the seat mounting hardware located under the seat and adjust the seat forward or rearwards to a length that is comfortable for the operator to raise and lower the mower deck with his right foot. Tighten the seat mounting hardware once the seat is adjusted. UPPER CONTROL LEVER ADJUSTMENTS IMPORTANT: Do not make adjustment to the lower control levers since they are already adjusted for neutral creep. The control levers may be adjusted while in the neutral position for height, reach and forward travel to fit the operator s steering comfort zone. HEIGHT ADJUSTMENT Refer to Figure 3-4: 1. Adjust control levers vertically by removing the bolts, flat washers, and locknuts that attach the upper control levers to the lower control levers. 2. Reposition upper control levers to a height that fits the operator s personal preference. 3. Reassemble bolts, flat washers, and locknuts in the same order they were removed without tightening them. REACH ADJUSTMENT Refer to Figure 3-4 1. Pivot the upper control levers forward or backward to fit the operator s personal reach preference. If reach comfort zone can not be achieved, then try exchanging sides the levers are located: a. Remove the bolts, flat washers, and locknuts that attach the upper control levers to the lower control levers. b. Switch right control lever with left control lever and reassemble the bolts, flat washers, and locknuts in the same order they were removed without tightening them. c. Pivot the upper control levers forward or backward to fit operator s personal reach preference. 2. Verify that the control levers align with each other when in the neutral position and tighten the locknuts to the correct torque. Upper Control Lever Bolts with Flat Washers, and Locknuts Lower Control Lever Control Lever Adjustment Figure 3-4 23626 FORWARD TRAVEL ADJUSTMENT Refer to Figure 3-4: "REACH ADJUSTMENT" instructions are for adjusting the control levers to be equally aligned while in neutral. However, with this adjustment, the mower may want to steer slightly to the right or left when pushing the levers equally forward. Make the following adjustments if you prefer to have the levers equally aligned while in forward travel position instead of while in neutral position: 1. While driving forward, make the necessary steering correction required to make the unit go straight and take careful notice of how the upper control levers are positioned. (The distance one lever is ahead of the other to make the mower travel straight.) 2. Stop the mower on a level surface, place the control levers in neutral, shut the power off and remove the switch key. 3. Either adjust the upper trailing lever forward by the distance it was trailing or adjust the upper leading lever back by the distance it was leading. Tighten the locknuts to correct torque. Example: If the right control lever is one inch ahead of the left control lever, stop the unit and either adjust the right upper control lever back one inch or adjust the left upper control lever forward one inch. 66 Z44 and Z52 Accu-Z Razor (S/N 472620 and above) Riding Mowers 357-044SM 9/24/09
Land Pride SECTION 8: ADJUSTMENTS HYDRO-DRIVE BELT BELT ADJUSTMENT The pump drive belt tension remains constant by means of a tension idler and spring. There is no tension adjustment of this belt. DECK LEVELING ADJUSTMENTS The spindle belt remains in constant tension by means of a spring tensioned idler. The spring tension should be adjusted so that the belt does not slip under normal operating load conditions and may require readjusting as the belt stretches and wears. The belt should be replaced if it is excessively worn or damaged. Refer to Figure 3-5 and Figure 3-6: Check spring length to verify if belt is tensioned correctly. Installed spring length should be 4 3/4" +or- 1/8". Vary the spring length by adjusting the length of the eye bolt. Eye Bolt (Adjust Length To Vary Spring Tension) Anchor Bracket Spring Tension Idler ENGINE RPM SETTING The Razor is designed so that the engine will run at 3600 rpm static pump load only. At this speed the hydraulic pumps are running at their maximum rated speed. DECK LEVELING & HEIGHT ADJUSTMENTS The mower deck has three areas that may need to be checked and adjusted periodically. Before considering any mower deck leveling adjustments, check that the tire air pressure is within the specified range.! WARNING Stop engine. Make sure blade engagement switch is in the down (OFF) position. Place control levers in park position and set park lever to (ON) before leaving machine. DECK LEVEL ADJUSTMENTS Leveling the deck must be done in the following order: 1. Check tire pressures to make certain they are properly inflated before leveling deck.

Not enough belt tension may also lead to premature belt damage due to excessive belt slippage. IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley. 2. Park the unit on a flat surface. Refer to Figure 3-7: 3. Raise deck fully up. 4. Position the blade cutting height at 3 1/4 by placing 3" high deck support blocks under the deck edge in three locations: a. Place two of the 3" support blocks under the deck front edge in-line with the far left and far right blade spindles. b. Center the third 3" support block under the deck back edge.
