Important: Always adjust the Number of Spacers below Caster Hub to correspond to the Axle Position as shown in table to obtain proper “rake” (blades should always be level to the ground or tipped slightly down at the front).

Adjusting the Axle Position

3. Raise the rear of the machine up onto jack stands

Desired cutting height range can be obtained by

and remove the drive wheels.

 

adjusting the rear axle and placing caster spacers

 

above or below the caster arm (see Figure 9 and

 

Figure 10 along with the Cutting Height Adjustment

 

Chart).

 

To adjust rear axle:

 

1. Stop the machine and move the drive levers to

 

the neutral lock position.

 

2. Disengage the PTO.
