TO CHECK BRAKE
If tractor requires more than five (5) feet to stop at highest speed in highest gear on a level, dry concrete or paved surface, then brake must be serviced.
You may also check brake by:
•Park tractor on a level, dry concrete or paved surface, depress brake pedal all the way down and engage parking brake.
•Disengage transmission by placing freewheel control in “transmission disengaged” position. Pull freewheel control out and into the slot and release so it is held in the disengaged position.
The rear wheels must lock and skid when you try to manu- ally push the tractor forward. If the rear wheels rotate, then the brake needs to be serviced. Contact a qualified service center.
TO LEVEL MOWER
Make sure tires are properly inflated to the PSI shown on tires. If tires are over or under inflated, it may affect the appearance of your lawn and lead you to think the mower is not adjusted properly.
VISUAL
•With all tires properly inflated and if your lawn appears unevenly cut, determine which side of mower is cutting lower.
NOTE: As desired, you can raise the low side of mower or lower the high side.
•Go to side of mower you wish to adjust.
•With a 3/4" or adjustable wrench, turn lift link adjust- ment nut (A) to the left to lower the mower, or, to the right to raise the mower.

NOTE: Each full turn of adjustment nut will change mower height about 3/16".
•Test your adjustment by mowing some uncut grass and visually checking the appearance. Readjust, if necessary, until you are satisfied with the results.
PRECISION
•With all tires properly inflated, park tractor on level ground or driveway.
CAUTION: Blades are sharp. Protect your hands with gloves and/or wrap blade with heavy cloth.
•Raise mower to its highest position.
•At both sides of mower, position blade at side and measure the distance (A) from bottom edge of blade to the ground. The distance should be the same on both sides.
