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 drive levers 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.After adjusting the height of cut, adjust the anti-scalp rollers by removing the whizlock nut and spring disc washer.

6.Adjust anti-scalp rollers for Normal Operating Conditions. Place rollers in one of the positions shown in Figure 8. Rollers will maintain 3/4 inches (19 mm) clearance to the ground to minimize gouging and roller wear or damage.

Note: For Maximum Deck Flotation, place rollers one hole position lower. Rollers should maintain 1/4 inch (6.35 mm) clearance to ground. Do Not adjust rollers to support the deck. Be sure roller bolts are installed with the spring disc washer between head of the nut and mounting bracket.

Figure 8

For cutting heights above 3.5 inches (38 mm) use the bottom hole. The rollers will still be effective against scalping.

Transporting

Transporting a Unit

WARNING

Loading the mower onto a trailer without strong enough or properly supported ramps could be dangerous. The ramps could collapse causing the unit to fall, which could cause injury.

•Use proper ramps that are secured to the truck or trailer.

•Keep feet and legs out from under the unit when loading and unloading.

•If necessary, use assistance when loading.

Consult the NFPA 58: Liquefied Petroleum Gas Code for additional information regarding LPG transportation.

•Be sure the fuel valve is closed.

•Place spare LPG tank(s) in a DOT approved storage cage.

–Transport tanks in an upright, vertical and secure position to minimize movement, tipping, or physical damage relative to other tanks or to the storage cage while in transit.

–Place tanks so that valves, fittings, or gauges are protected from physical damage during transport.
