• To start the machine, the parking brake must be engaged.
• It does not matter whether the PTO switch is on or off, nor does it matter if the control levers are pulled in or extended out.
  • As long as the parking brake is engaged, the machine will start. When the parking brake is applied, the control levers cannot be moved.
• Park brake engagement returns motion-control levers to the neutral position.

A foot pedal is used to raise the mower deck to adjust cut height or lock the mower deck in the transport position:

• A foot pedal is easier for many operators to use than a hand lever.
• Adjustable spring assist allows fine-tuning lift effort to the mower and the operator.

Cut-height adjustment

An easy-to-use height-of-cut adjustment lift system allows the operator to quickly adjust deck height for different mowing applications as well as transport:

• 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).
• 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.
• 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 locked in the transport position and returned to the previous HOC.

• Use the foot-lift pedal to lift the deck, then engage the transport lock.
• To unlock and lower the deck, simply pull up on the transport unlock knob, adjust the dial, and release the deck lift assist pedal to lower the deck to the chosen height.

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