The cutting unit 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.
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.

The cutting unit is suspended at the rear with the lug 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 cutting unit 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 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 horizontal
connecting rod and the tongue of the forward 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 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 cutting unit
cover's parallelism with the ground. See 'Checking and adjusting the cutting unit's parallelism'.
