Operation

Driving in Reverse

1.Move the motion control levers inward to the neutral operate position.

2.To move rearward in a straight line, move both levers rearward with equal pressure.

To turn right, release pressure on the RH motion control lever and the rear of the machine will move towards the rear and to the right.

To turn left, release pressure on the LH motion control lever and the rear of the machine will move towards the rear and to the left.

3.To stop, position both motion control levers in the neutral operate position.

Adjusting the Cutting Height

The cutting height of the mower deck is adjusted from 1 to 5 1/2 inches (2.5 cm to 14 cm) in 1/4 inch (6.4 mm) increments.

1.Stop the machine and move the motion control levers outward to the neutral locked position.

2.Disengage the PTO.

3.Position the transport lock in the latching position.

4.Raise and lock the deck to the 5 1/2 inch (14 cm) transport position (Figure 16).

The deck is raised by pushing the foot operated deck lift pedal forward. The pedal is located at the front right corner of the floor pan.

Note: When changing the cutting height positions, always come to a complete stop and disengage the PTO.

Adjusting the Anti-Scalp Rollers

It is recommended to change the anti-scalp roller position, when the height of cut has changed.

1.Stop the machine and move the motion control levers outward to the neutral locked position.

2.Disengage the PTO.

3.Engage the park brake.

4.Stop the engine, remove the key and wait for all moving parts to stop.

5.After adjusting the height of cut:

LZZ-LP Units: Adjust the anti-scalp rollers by removing the bushing, spring disc washer and bolt.

LZAS-LP Units: Adjust the anti-scalp rollers by removing the nyloc nut, bushing, spring disc washer and whizlock nut.

6.Place the rollers in one of the positions shown (Figure 17). Rollers will maintain 3/4 inch (19 mm) clearance to the ground to minimize gouging and roller wear or damage.

Figure 17

For cutting heights above 3.5 inches (90 mm) use the bottom hole. The rollers will still be effective against scalping.
