Design and function
The mowing deck is raised and lowered using the
mechanical lifting lever, which actuates a shaft that
rotates.
When the shaft rotates, the chain that is secured in
an arm on the inner end of the shaft raises or
lowers the tool frame.
The mowing deck is rear suspended with the lug on
the rear transverse axle in a U-bracket on the tool
frame. The front of the tool frame is linked to a
bracket on the attachment. The front rollers are
supported against the ground, for example, when
turning when the attachment tends to lean. The
rollers on the rear section of the protective frame
are used when removing and fitting the mowing
deck or moving it to the service position.
Otherwise, when dismantling, the rear of the
attachment would fall directly to the ground when
the lug on the rear axle releases its grip.
The mowing height is adjusted using the lever,
which has a catch for the different mowing height
positions. The setting for the mowing height range
is located on the same axle, see Adjustment of the
mowing height range. Two connecting rods via a

There are two struts on the top of the cutting unit
cover. The upper one is coupled between the
horizontal connecting rod and the tongue of the
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 (parallel strut) is
connected between the front and rear transverse
axles, so that even the rear axle rotates in the same
way as the front axle. There is an adjuster on the
parallel strut to adjust the mowing deck covers
parallelism with the ground. See Checking and
