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 attachment's lifting device
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. Other-
wise, 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,

DESIGN AND FUNCTION
When lowering the unit, the two connecting rods,
via the three-point link, will alter the belt adjuster
so that the drive belt is tensioned and the blades
begin to rotate.
When the attachment is raised the microswitch in
the safety circuit is actuated.
via an angular link, activate the protective frame
around the cutting unit and raise or lower the
cutting unit cover within the cutting height range.
There are two struts on the top of the cutting unit
cover. The upper one is coupled between the hori-
zontal connecting rod and the tongue of the for-
ward perpendicular shaft on the top of the cutting
unit cover. When the shaft is rotated, it will raise or
lower the cutting unit cover in relation to the pro-
tective frame. The lower strut (parallel strut) is con-
nected 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 cutting unit cover's
parallelism with the ground. See "Checking and
adjusting the mowing deck's the parallelism".
