Operation

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.

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.

8.Torque the 3/8–16 whizlock nut to 27-33 ft-lb (37-45 N-m) (Figure 18).

9.Torque the 3/8 nyloc nut to 27-33 ft-lb (37-45 N-m).

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

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.

Transporting

Transporting a Unit

Use a heavy-duty trailer or truck to transport the machine. Lock brake and block wheels. Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes. Be sure that the trailer or truck has all necessary lighting and marking as required by law. Secure a trailer with a safety chain.
