Operation

Figure 7

Left Hand Side Shown

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 spring disc washer and bolt (see step 7).

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 bolt 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.
