Operation

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.

Figure 17

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

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 lock 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.Adjust the anti-scalp rollers by removing the bushing, spring disc washer and bolt.

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.

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 roller bolts are installed with the spring disc washer between the head of the bolt and the mounting bracket (Figure 18).

8.Torque the 3/8–24 x 2 Gr 8 hex capscrew to 50–55 ft-lb (68–75 N-m) (Figure 18).
