CUTTING HEIGHT ADJUSTMENT

WARNING

Before checking mower, shut off PTO and engine. Allow all moving parts to stop. Remove ignition key, then disconnect the spark plug wire and fasten it away from the spark plug.

The cutting height adjustment pin (A, Figure 29) controls the mower cutting height. The cutting height is adjustable between 1-3/4” (4.4cm) and 5” (12.7cm) in 1/4” (.64cm) increments.

Depress the deck lift foot pedal (B, Figure 29), placing the majority of the force on the top edge of the pedal until it locks into the “TRANSPORT” position. Place the cutting height adjustment pin in the desired cutting height. Depress the deck lift foot pedal, placing the majority of the force on the bottom edge of the pedal to release the pedal from the “TRANSPORT” position.

Adjust the length of the deck lift spring by tightening or loosening the (2) 5/8” hex nuts that are closest to the spacer at the front end of the spring (see Figure 30). After adjustment is made, tighten these two nuts together. Perform this step to both springs.
