3.04 - Cutting Height Adjustment
WARNING: Keep hands and feet away from moving blades.
Be sure the tractor engine is off, parking brake is locked, and key is removed
before making any adjustments.
Never rely on the hydraulic system to hold the weight of the raised mowers.
Never walk or work under the raised mowers without first making sure the
automatic locking system is securely holding the wing units with the hydraulic
cylinders closed, and the hook is engaged to support the rear deck.
The cutting height is the distance from the blades to the ground. The cutting height is
adjusted by moving the height adjustment spacers on the wheel yokes above or
below the wheel arm. Placing spacers between the wheel arm and the wheel yoke
raises the cutting height by the size of the spacer. Removing the spacers lowers it by
the same height (see fig. 5). All the wheel yokes are supplied with three different size
height adjustment spacers, ¼”, ½” and 1”.
Be sure all 12 wheels of the mowers are adjusted equally. This is the only way to
ensure a completely uniform cut.
IMPORTANT: Very low cutting heights should be avoided. Damaging shock loads
occur when the blades strike the ground repeatedly. This can cause damage to
the mower.
Cutting lower than 2” under most circumstances should be avoided.
The cutting height is adjustable from 1” to 5”.
