deck lift assist lever 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.

6.Place the rollers in one of the positions shown (Figure 9). Rollers will maintain 3/4 inch (19 mm) clearance to the ground to minimize gouging and roller wear or damage.

4.Insert the height adjustment pin into the hole corresponding to the desired cutting height and install the hairpin cotter pin.

See the decal on the side of the deck lift plate for cut heights.

5.Move the deck height lever out of the transport position (or 5 inch (12.7 cm) cutting height) and down onto the height adjustment pin to mow at selected height.

Note: The foot operated deck lift assist lever can be used to momentarily lift the deck to clear objects. Be sure that PTO is disengaged.

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, adjust the anti-scalp rollers by removing the nyloc nut, bushing, spring disc washer and whizlock nut.

For Maximum Deck Flotation, place the rollers one hole position lower. Rollers should maintain 1/4 inch (6.4 mm) clearance to the ground. Do Not adjust the rollers to support the deck.

7.Be sure the whizlock nuts are installed with the spring disc washer between the head of the nut and the mounting bracket.

Note: The foot operated deck lift assist lever can be used to momentarily lift the deck to clear objects. Be sure that PTO is disengaged.

8.Torque the 3/8–16 whizlock nut to 30-35 ft-lb (41-47 N-m) (Figure 10).

9.Torque the 3/8 nyloc nut to 30–35 ft-lb (41-47 N-m).
