OPERATION

For best cutting performance, grass over 6 inches in height should be mowed twice. Make the first cut relatively high; the second to desired height.

TO ADJUST GAUGE WHEELS (See Fig. 7)

Gauge wheels are properly adjusted when they are slightly off the ground when mower is at the desired cutting height in operating position. Gauge wheels then keep the deck in proper position to help prevent scalping in most terrain conditions.

Adjust gauge wheels with tractor on a flat level surface.

Adjust mower to desired cutting height (See “TO AD- JUST MOWER CUTTING HEIGHT” in the Operation section of this manual).

With mower in desired height of cut position, gauge wheels should be assembled so they are slightly off the ground. Install gauge wheel in appropriate hole with shoulder bolt, 3/8 washer, and 3/8-16 locknut and tighten securely.

Repeat for opposite side installing gauge wheel in same adjustment hole.

If stopping is absolutely necessary, push clutch/brake pedal quickly to brake position and engage parking brake.

Move motion control lever to neutral (N) position.

IMPORTANT: THE MOTION CONTROL LEVER DOES NOT RETURN TO NEUTRAL (N) POSITION WHEN THE CLUTCH/BRAKE PEDAL IS DEPRESSED.

To restart movement, slowly release parking brake and clutch/brake pedal.

Slowly move motion control lever to slowest setting.

Make all turns slowly.

TO TRANSPORT (See Figs. 5 and 9)

When pushing or towing your tractor, be sure to disengage transmission by placing freewheel control in freewheeling position. Free wheel control is located at the rear drawbar of tractor.

Raise attachment lift to highest position with attach- ment lift control.

Pull freewheel control out and down into the slot and release so it is held in the disengaged position.

Do not push or tow tractor at more than two (2) MPH.

To reengage transmission, reverse above procedure.

NOTE: To protect hood from damage when transporting your tractor on a truck or a trailer, be sure hood is closed and secured to tractor. Use an appropriate means of tying hood to tractor (rope, cord, etc.).
