Hustler Turf Z4 manual Mower deck operation, Deck cutting height adjustment, Anti-scalp wheels

If the machine’s forward motion must be stopped while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged.

WARNING: Never direct discharge of material from mower deck towards bystanders. Do not operate the mower without either the discharge chute or the entire grass collection system in place. Figure 3-10

Mower deck operation

DANGER: Never attempt to make any adjustments to the mower deck while the engine is running or with the deck drive clutch engaged. Mower blades cannot be seen and are located very close to deck housing. Fingers and toes can be cut off instantly.

With the engine running, engage the deck clutch switch (Figure 3-1) and advance engine throttle to full rpm.

NOTE: Engaging the deck clutch at high engine rpm or when under heavy load (in tall grass for example) can cause belts and/or electric clutch to slip, resulting in premature wear or possible damage.

Deck cutting height adjustment

Deck height is adjustable from 1-1/2” to 4-1/2” (3.81 cm -

11.43cm) in 1/4” (.64 cm) increments. The holes in the height adjusting bar are spaced at 1/2” (1.27 cm) intervals. By turning the height adjusting stop around, 1/4” (.64 cm) increments can be attained due to the 1/4” (.64 cm) plate that is part of the stop. Figure 3-11

EXAMPLE: When the height adjusting stop is placed in the 1-1/2” (3.81 cm) hole, with the 1/4” (.64 cm) plate facing to the front of the unit, the cutting height is at 1-1/2”. When the height adjusting stop is placed in the 1-1/2” (3.81 cm) hole, with the 1/4” (.64 cm) plate on the operator’s side of the hole, the cutting height is at 1-3/4” (4.45 cm).

The notch located at the rear of the height adjusting bar is to be used when the deck is placed in the transport mode.

Anti-scalp wheels

Anti-scalp wheel kits are standard on Hustler Mid Mount Z units. These anti-scalp wheels are designed to minimize scalping when mowing on rough uneven terrain.

After setting the cutting height, adjust the front anti-scalp wheels so they extend below the deck but do not contact the ground. They should always be at least 1/4” to 3/4” (6.35mm to 19.05mm) below the deck. With the unit sitting on a flat level surface, the front wheel position can be adjusted up or down as needed from 3/4” to 1-3/4” (19.05mm to 44.45mm) below the blade surface. Move the front wheels up or down, in 1/2” (12.70mm) increments, using the different axle mount holes in the wheel mount bracket. Figure 3-12

When adjusting the rear anti-scalp wheels, the wheel should be in the lower axle mount hole when the front anti-scalp wheels are in the lower or middle axle mount holes. When the front wheels are in the upper axle mount hole, the rear wheels should be in the upper axle mount hole as well.

NOTE: When the anti-scalp wheels are installed, the mini- mum cutting height is 1-1/2” (3.81 cm) with the anti-scalp wheels set at 3/4” (1.91cm).
