When the two front support rod hairpins are removed from the mower deck, the weight of the tractor section may cause the front frame of the unit to rise suddenly. If the unit rises suddenly, injury may occur.

Securely hold down the front of the unit when the front support rod hairpins are removed.

The cutting height of the mower deck is adjusted from 1 1/2 to 4 1/2 inches (3.81 cm to 11.4 cm) in 1/2 inch increments.

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.Install hairpin clips in the holes for the desired cutting height. See Figure 6.

Important: To maintain correct cutting height and rake, check the following for proper adjustment.

A.The front and rear hairpins are in the same holes with the proper spacers under the hair pins. See Figure 6.
