Easy-to-operate height-of-cut adjustment enables on-the-go changes

Mower deck height adjustment knob

An easy-to-use cutting-height lift system allows the operator to adjust the mower deck height with no tools and minimal effort. The easy-to-grip knob allows operators to dial in the desired height of cut (HOC).

Cutting height can be adjusted from approximately 1 in. to 5.5 in. (2.5 cm to 14 cm). Each increment on the knob adjusts the HOC approximately 0.25 in. (0.64 cm). The deck can also be raised and locked in a transport position to provide maximum ground clearance when moving the machine from one area to another.

The transport lock function allows the deck to be returned to the previous HOC after being in the transport position:

• Use the foot-lift pedal to lift the deck and engage the transport lock.
• Rotate the knob to adjust from 1 in. to 5.5 in. (2.5 cm to 14 cm) in 0.25-in. (0.64 cm) increments.

This design increases productivity by allowing operators to change the cutting height without having to leave the seat.
