Original purchaser of this unit was instructed by the seller on safe and proper operation. If unit is to be used by someone other than original purchaser; loaned,

rented or sold, ALWAYS provide the Operator’s Manual and any needed safety training before operation.

2.6 PREPARATION

Before starting any removal of parts, proper preparation is very important for efficient work. A clean work area at the start of each job will allow you to perform service repairs easily and quickly.

To reduce the incidence of misplaced tools or parts, place removed components with all attaching hardware in the disassembly order on a clean work surface. Organization is a key part of proper reassembly.

T ools, instruments, and parts needed for the job should be gathered before work is started. Interrupting a job to locate tools or parts is a needless delay. A list of required special tools has been included in this manual.

2. If jacks are not available, place support blocks under both transaxles at the rear of unit.

Always block wheels and know

2.8 CLEANING AND STORAGE

IMPORTANT:

outdoors to help prevent sealed bearing rust or corrosion. Water can seep into sealed bearings and reduce component life. Bearings are sealed against dirt and debris only.

A unit that is excessively dirty should be cleaned before work starts. Cleaning will occasionally uncover trouble sources. Dirt and abrasive dust reduce the efficient work life of parts and can lead to costly replacement.

When taking unit out of extended storage:

1. Check for any damage or loose parts. Repair replace, or tighten hardware before operation.

4.9 TO LEVEL MOWER

Adjust the mower while tractor is parked on level ground or driveway. Make sure tires are properly inflated (See Specifications). If tires are overinflated or underinflated, you can not properly adjust your mower.

To Check Side to Side Level

1. Position unit on a smooth, flat, level surface. Set proper tire pressure.

2. Position blade(s) side to side; measure distance of blade tips to floor at right and left side of mower pan. Rotate blade(s) 180 measurement should be equal within 1/16 inch side to side.

NOTE:

To make measuring distance from blade to ground easier, obtain a wood block about 1 inch square by 5 inches long. Wrap the entire block with masking tape. Hold block in vertical position with its lower tip on ground. Push block against cutting edge of blade so as to make a mark on tape. Pull the block away and with a ruler measure the distance from lower block tip to mark.

To Adjust Side to Side Level (48" Deck)

1. Loosen height adjuster nuts.

2. Remove hair pins and washers holding height adjusters to lift arm and unhook height adjusters from lift arm.

3. On low side: Turn height adjuster nut clockwise on low side of mower pan to raise low side. Raise low side one half the measured difference in height between the low side and the high side. On high side: Turn height adjuster nut counterclockwise to lower high side the other one half of the height difference.

4. Hook height adjusters onto lift arm and check side to side level. If not level, continue to turn height adjusters until deck is level side to side.

5. Tighten height adjuster nuts.

6. Secure height adjusters with washers and hair pins.

To Adjust Side to Side Level (42" Deck)

1. Place anti-scalp rollers in highest position so they do not touch the ground during adjustment.

2. Put height adjustment lever in the number three (3) position.

3. With a 1/2" open-end wrench, adjust the nuts on the bottom of the adjuster link until each end of the blade is 2-3/4" from the ground within 1/16".

4. Reset anti-scalp rollers to match desired attachment position.

CONTROL)

1. Stop the engine. Remove the ignition key. Push the PTO knob into the "OFF" position.

CAUTION:

ALWAYS MAKE CERTAIN that jack(s) or blocks used are stable, strong and will support the weight of the unit.

2. Place jack(s) under rear transaxles only. If jack(s) are not available, place support blocks under both transaxles at the rear of the unit to raise the rear wheels off the ground.

3. Remove side shrouds.

4. Place a weight on the seat to close the seat switch. Start the engine and run it at part throttle.

5. Remove the connecting linkage from the flange bushing, Figure 12.

6. Rotate flange bushing until the wheel stops rotating.

7. Lock the flange bushing in place by tightening the lock nut.

8. Adjust the connecting rod length and reattach it to the flange.

9. Loosen the lock nut and test by moving the steering control levers.

10.Repeat procedure for the other side of the unit.

11.Reinstall side shrouds.

If the drive cannot be adjusted to neutral using the above procedure, the link to the flange on the transaxle can be adjusted.

1. With the rear of the unit jacked up and supported, remove the connecting linkage at the flange (Figure 11).

2. Place a weight on the seat and start the engine. Run it at part throttle.

3. Rotate the flange until the wheel stops turning and tighten the lock nut.

4. Shut off the engine.

5. Loosen the lock nut on the connecting linkage and adjust the rod end to match the hole in the flange.

6. Reattach the connecting linkage and tighten the lock nut to the rod end.

7. Loosen the flange lock nut and test.

PREVENT personal injury!

4.11 ADJUSTING THE UNIT TO TRACK STRAIGHT

The primary reason the unit may not track straight is incorrect or unbalanced tire air pressure.

1. First, check and adjust the tire pressure.

2. With tire pressures equal and the rear of the unit on jack stands, check the circumference of the tire. If one tire is larger than the other, increase pressure in the small tire and/or decrease pressure in the larger tire.

3. With both tires the same size, set the control handles. The roller bearing on the speed control arm must be in the neutral position on the neutral detent strap.

4. Adjust upper control arm linkage until the control handles will enter the neutral switch slot and activate the neutral switches.

5. Tighten locking nuts on the control linkage.

6. Disconnect linkage from the transmission, loosen two cap screws in the speed control arm and position pump weldment in the horizontal position and tighten cap screws.

7. Start unit and by hand adjust the transmission control cam until neutral is found.

8. Tighten a transmission locking nut.

9. Stop engine.

10.Set transmission linkage rod, then line up with hole in control cam and install and tighten attachment ball.

11.Loosen the transmission control locking nut.

12.Start unit and check tracking.

4.12 ANTI-SCALP ROLLERS (42" DECK)

Rollers are intended to prevent lawn scalping, not to control cutting height.

For proper operation, adjust the anti-scalp rollers to the same or higher than mower cutting height. For example, when mowing at the number three (3) height position, the anti-scalp rollers must be adjusted to their number three (3) or higher position.

Figure 12

For final tracking adjustment:

1. Remove side shrouds. Set aside.

2. Loosen bolts which attach the eccentric to the seat support. Do not remove the bolts.

3. Rotate eccentric to adjust the travel of the speed control arm. The thicker portion of the eccentric shortens the distance the steering control lever will travel forward. The thinner portion of the eccentric lengthens the distance the steering control lever will travel forward.

5. Tighten the eccentric’s bolts.

6. Reinstall the side shrouds.
