4.9 TO LEVEL MOWER
Adjust the mower while tractor is parked on level ground or driveway. Make sure tires are properly inflated (See Specifications). If tires are overinflated or underinflated, you can not properly adjust your mower.
To Check Side to Side Level
1.Position unit on a smooth, flat, level surface. Set proper tire pressure.
2.Position blade(s) side to side; measure distance of
blade tips to floor at right and left side of mower pan. Rotate blade(s) 180o and check again. The measurement should be equal within 1/16 inch side to side.
NOTE: To make measuring distance from blade to ground easier, obtain a wood block about 1 inch square by 5 inches long. Wrap the entire block with masking tape. Hold block in vertical position with its lower tip on ground. Push block against cutting edge of blade so as to make a mark on tape. Pull the block away and with a ruler measure the distance from lower block tip to mark.

4.11 ADJUSTING THE UNIT TO TRACK STRAIGHT
The primary reason the unit may not track straight is incorrect or unbalanced tire air pressure.
1.First, check and adjust the tire pressure.
2.With tire pressures equal and the rear of the unit on jack stands, check the circumference of the tire. If one tire is larger than the other, increase pressure in the small tire and/or decrease pressure in the larger tire.
3.With both tires the same size, set the control handles. The roller bearing on the speed control arm must be in the neutral position on the neutral detent strap.
4.Adjust upper control arm linkage until the control handles will enter the neutral switch slot and activate the neutral switches.
5.Tighten locking nuts on the control linkage.
6.Disconnect linkage from the transmission, loosen two cap screws in the speed control arm and position pump weldment in the horizontal position and tighten cap screws.
