5.2.4Engine to Cutter Deck Belt: No adjustment necessary.

5.2.5Transmission Belt Adjustment:

a)Stop engine and wait for all moving parts to stop. Remove key or spark plug wire(s).

b)To tighten transmission belt, loosen the 3/8” nyloc nut on transmission belt idler pulley. Slide bolt inward in slot and retighten nyloc nut.

c)When properly adjusted, the belt should have 1/2” (12 mm) of deflection with three pounds (13.3 Nt) of pressure on the belt midway between the transmission and engine pulley.

5.2.6Wheel drive belts and scrapers:

Be sure mud and grass scraper, on each side, is adjusted properly and centered in the pulley grooves. The pointed part of the scraper should be centered and as deep in the pulley groove as possible without rubbing at any point.

NOTE: Wheel drive springs have three tension settings. See Section 5.2.11.

5.2.7Brake Adjustment:

See 3.11 steps c) and d)

5.2.8Wheel drive linkage adjustment: See 3.11 steps a) and b)

5.2.9Shifter lever adjustment:

See 3.10

5.2.10Shifter detent adjustment:

Transmission shifter detent can be adjusted by adjusting the setscrew on the backside of transmission located just behind the neutral start switch. Turn setscrew in (clockwise) to hold the transmission shifter more positively in each gear and to increase the force on the lever required to shift gears.

Turn setscrew out (counterclockwise) to decrease force on lever required to shift gears. Factory setting is to turn setscrew all the way in then back out 1-1/2 turns.

IMPORTANT: Screwing setscrew in too far will prevent the transmission from shifting.

5.2.11Wheel drive spring tension adjustment:

It may be necessary to increase wheel drive belt tension under certain conditions such as, wet grass, hilly terrain, or while pulling a sulky.

a)Stop engine, wait for all moving parts to stop, and remove key or spark plug wire(s).

b)Disengage neutral lock/park brake latches and release drive levers to lower spring force.

c)Remove the 5/16-18 whizlock nut securing the adjustment bolt to the drive wheel shield. Locate bolt assembly in the desired position as follows

Position A - Normal Conditions Position B - More Severe Position C - Most Severe

NOTE: Lever force is lowest with bolt assembly in Position A and will increase in Positions B and C (See Figure 15).
