3.4. With the engine OFF have a helper engage the

blade drive. Measure the distance between the

center of the idler pulley and the left drive pulley.

The measurement should be between 5 1/2” and

5 5/8”. See Figure 11.

NOTE: If the blade drive belt slips during opera-

tion it may be necessary to slide the idler pulley

forward in the slot on the idler arm. Loosen the

hardware on the idler pulley and slide the pulley

forward slightly. Tighten the hardware. See Fig-

ure 8.

IMPORTANT: The blades must come to a com-

plete stop when the blade engagement lever is

released.

blade drive control lever releases during opera-

tion.

4.1. With the engine off, engage the operator pres-

ence control and the blade drive control. See

fully engaged. See Figure 13.

4.3. To adjust, remove the hairpin clip on the upper

end of the operator presence control arm.

4.4. Loosen the hex nut and shorten the rod by one

IMPORTANT: Time the blades properly during

reassembly. Set the cutting blades perpendicular

to each other during installation of the toothed

drive belt.There are arrows cast into the cogged

pulleys to help align the blades. Offset these

arrows by 90 degrees. See Figure 18.

NOTE: The arrows do not indicate the blade

position. Blades are 90 degrees offset from the

arrow position.

5.10. Rotate the tension adjustment bracket into posi-

tion and apply tension to the spindle housing

and cogged belt.

5.11. Tighten the adjustment bracket screw.

5.12. Tighten the four spindle mounting bolts to 15 ft.

lbs.

NOTE: Proper belt tension is achieved when the

belt deflects approximately 1/2 inch at the mid-

point between the pulleys when applying moder-

ate finger pressure.

5.13. Reinstall the blade drive belt over the left drive

spindle.

5.14. Install the belt cover.

7.6. Use a 9/16 inch socket to loosen the cap screw

securing the transmission pulley belt guide to the

frame and engine mount. Pivot the belt guide

away from the pulley. See Figure 24.

7.7. Using a 1/2 inch socket, loosen the nut securing

the rear belt support bracket to the transmission.

Pivot the belt support away from the belt. See

Figure 25.

7.8. Remove the wheel drive belt from the engine

sheave, backside idler and the transmission pul-

ley. See Figure 26.

7.9. Install a new belt in the reverse order.

NOTE: The new belt must be installed inside

out. The “V” side of the belt lies against the

engine sheave only. The flat side of the belt lies

against the transmission pulley and idler pulleys.

8. WHEEL DRIVE BELT ADJUSTMENT

The wheel drive belt requires adjustment when belt

slippage occurs. This is most noticeable when more

traction is needed (such as going up slopes).

8.1. Remove the hair pin clip from the upper end of

the wheel drive control rod. Slide the rod out of

the lever assembly. See Figure 27.

8.2. Using a 9/16” opened end wrench, loosen the

jam nut on the lower end of the rod. See Figure

28.

8.3. Thread the rod one or two turns clockwise for

more tension.

8.4. Insert the rod back into the hole in the wheel

drive control lever and install the hairpin clip.

8.5. Test the operation of the unit. Repeat the adjust-

ment if necessary.

NOTE: Most comfortable operation will be

obtained when the adjustment allows the lever to

just make contact with the hand grip when suffi-

cient traction is achieved.

8.6. When adjusted properly, tighten the lower jam

nut against the block.

9. WHEEL BRAKE ADJUSTMENT

This adjustment may be required it the unit does not

hold on a hill with the operator presence control disen-

gaged, or if the brake drags with the operator presence

control engaged and the transmission is in neutral.

(The unit should roll freely in this position.)

NOTE: With the operator presence control

released there should be a 3/8” to 5/16” gap

between the back of the brake arm and the

bracket. See Figure 29.

Figure 29

3/8” to 5/16” Gap

Adjustment Nut

9.1. To adjust use a 1/2” wrench to make a small (1/4

turn) adjustment to the brake locknut until the

correct measurement is achieved. It may be nec-

essary to relieve spring tension when decreas-

ing distance. Have an assistant engage the

operator presence control while you adjust the

nut. See Figure 30.

10. TRANSMISSION NEUTRAL ADJUSTMENT

With the unit turned off and the shift lever in the neutral

detent position you should be able to hold down the

operator presence control and roll the unit easily for-

ward and back. Check this from forward and reverse

positions. If the unit is in gear you will need to perform

a neutral adjustment.

10.1. Place the shift lever in the neutral detent position

of the console. See Figure 31.

10.2. Remove the hairpin clip securing the shift link

and lower it from the shift rod. See Figure 32.

10.3. Moved the shift arm back and forth as necessary

into each detent until the transmission is in neu-

tral.

NOTE: Moving the shift arm clockwise all the

way to the left, and then one notch counterclock-

wise should put the transmission in neutral. With

the operator presence control lever down you

should be able to easily roll the unit.

10.4. With the transmission in neutral, rotate the shift

link until the hooked end easily fits into the hole

at the bottom end of the shift rod. See Figure 32.

NOTE: The shift rod must be held in the neutral

position while the shift link is adjusted.

10.5. Secure the shift link into the shift rod with the

hairpin clip removed earlier.

10.6. Recheck the neutral position and readjust i nec-

essary. Check from both the forward and reverse

direction.

11. DECK REMOVAL

securing the belt cover and remove the cover.

11.2. Remove the blade drive belt (see blade drive

belt removal section)

ing from the idler arm. Inspect the flange bush-

ing for wear.

15. INSTALLATION OF WHEEL DRIVE BELT

GUARDS - UPDATE

NOTE: Current production units have additional

belt guards installed at the factory. This update

will cover older units without pulley belt guards.

On older units the long run of the wheel drive belt cre-

ates several issues.

• The belt may come off one of the pulleys.

• The belt may not fully disengage from the engine

pulley, causing engine creep or hard shifting
