Tractor Top Link Adjustment
When the cutting height is set, adjust tractor top link until mower top link attachment point (A), Figure 4, is aligned vertically with mower hitch pin (B). The front tires of the mower will lift off the ground before the rear tires when the unit is raised. This will allow the mower to follow the ground contour.

Adjust Cutting Height
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
IMPORTANT
■Avoid low cutting heights. Striking the ground with blades produces one of the most damaging shock loads a mower can encounter. Allowing blades to contact ground repeatedly will cause damage to mower and drive.
1.Level mower from side to side. Check by measuring distance from mower frame to the ground at each deck rail.
2.Verify that the same amount of spacers are under all caster arms.
3.Control cutting height by adjusting front and rear caster wheels.
