is attached to the shaft with a joint and a spring.
The same shaft holds the adjuster for the cutting
height range. See "Adjusting the Cutting Height
Range" on page 65. Two connecting rods, via a
three-point link, activate the protective frame
around the cutting unit and raise or lower the
cutting unit cover within the cutting height range.
The horizontal connecting rod is housed in an
oblong groove in the equipment frame.
There are two struts on the top of the cutting unit

forward perpendicular shaft on the top of the
mowing deck cover. When the shaft is rotated, it
will raise or lower the cutting unit cover in relation
to the protective frame. The lower strut (the parallel
strut) is coupled between the tongues on the
forward and rear perpendicular shafts, so that the
rear shaft is also rotated in the same way as the
forward shaft. There is an adjuster on the parallel
strut to adjust the mowing deck cover's parallelism
with the ground. See "Parallelism" on page 64 for
adjustment instructions.
