HOW TO LEVEL THE MOWER HOUSING
If the mower housing is level, the blade will cut easier and the lawn will look better.
WARNING: Before you make an inspection, adjust- ment, or repair to the unit, disconnect the wire to the spark plug. Remove the spark plug wire to prevent the engine from starting by accident.
1.Make sure the unit is on a hard level surface.
2.Check the air pressure in the tyres. If the air pressure is incor- rect, the mower housing will not cut level. Make sure the tyres are inflated to 14 PSI. (1 BAR).
3.Move the lever for the blade rotation control to the DISENGAGE position. Move the lift lever to the number “4” cut- ting height position.
4.There are two adjustment procedures below that will level the mower housing.
THE FRONT TO BACK ADJUSTMENT
Before the height of the mower housing is measured, understand that the position of the blades in the mower housing are not the same in the front as they are in the back.
There are measuring points on the mower housing indicated by small round dimples (or X marks) on the front and rear, left and right sides of the mower housing (Figure 24). To determine if an adjustment is needed, use a ruler and measure the distance from the level surface to the bottom of the mower housing. In correct adjustment, the front of the mower housing at point B will be from 0” to 1/2” (0 mm to 12 mm) lower than the back of the mower housing at point D.

1.Disconnect both adjuster rods from the adjuster rod brackets (Figure 25).
2.Turn the adjustable nut clockwise to lower the front or counter- clockwise to raise the front of the mower housing.
3.Connect the left adjuster rod to the adjuster rod bracket. Check the housing for the correct adjustment. Fasten the ad- justable nut with the washer and hair pin.
4.On the right side, turn the adjustable nut until the adjustable nut is aligned with the hole in the adjuster rod bracket. Fasten the adjustable nut with the washer and hair pin.

THE SIDE TO SIDE ADJUSTMENT
Use a ruler and measure the distance from the level surface to the bottom of the mower housing. Measure from the locations indicated by the small round dimples (or X marks) at points A and C. In correct adjustment, the mower housing at points A and C must be within 1/4” (6 mm) of the same height. If the difference in the measurement is more than 1/4” (6 mm), adjust as follows.
1.Disconnect the adjuster plate from the mower housing (Figure 26).
2.Move the adjuster plate to the front to raise or to the back to lower the side of the mower housing. On some adjuster plates the holes have numbers. To raise the mower housing, move to a higher number.
3.Connect the adjuster plate.
4.Check the housing for the correct adjustment. If necessary, re- peat the adjustment.
