Note: The axle positions are in 1/2 inch (1.3 cm) increments and the large caster spacers are 1/2 inch (1.3 cm) thick. Therefore, by adjusting the same number of 1/2 inch (1.3 cm) caster spacers as axle hole positions the blades will retain the same front-to-back tip (rake).

Adjusting the Number of Spacers below Caster Support Hub

1.Stop the machine and move the drive levers to the neutral lock position.

2.Disengage the PTO.

3.Place the drive levers in the “park brake” position.

4.Push down on handles to lift front casters off the ground.

5.Support with jackstands.

6.Remove “quick pin” from one caster and remove caster from hub (see Figure 11).

7.Adjust the number of 1/2 inch spacers between bottom of hub and caster yoke to obtain the desired cutting height from the Cutting Height Adjustment Table in the Adjusting the Cutting Height section.

8.Install remaining spacers on top of hub.

10.Repeat for other caster.

Adjusting the Cutting Height with Blade Spacers

1.Stop the machine and move the drive levers 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.Blades may be adjusted for cutting height by using the four 1/4 inch (.64 cm) spacers found on the blade spindle bolts (factory setting is two above and two below). This allows a 1 inch (2.5 cm) range in 1/4 inch (.64 cm) increments of cutting height in any axle position. The same number of blade spacers must be used on all blades to achieve a level cut (two above and two below, one above and three below, etc.).

6.Raise front of deck and support with jack stands.

7.Hold blade bolt on bottom and loosen spindle nut on top.

8.Adjust number of spacers between bottom of spindle and blade as indicated in the Cutting
