PRESENTATION
Cutting unit
R 422 Ts AWD can be equipped with two different cutting
units. Combi 112 and Combi 122
The Combi-unit, equipped with a BioClip-plug, finely chops
the cuttings to fertiliser. Without the BioClip-plug the unit
works in the same way as a rear ejection unit. The rear ejector
ejects the clippings behind the unit without finely chopping
them.
Lever for hydraulic lift of
attachments
The lifting lever is used to put the cutting unit in either the
transport or mowing position when hydraulic pressure is
available.
When the lever is moved to the transport position, the blade
brake is automatically activated so that the blades stop within
about 5 seconds.
Lifting the Cutting Unit (Transport
Position)
Pull the lever backwards to engage the transport position. The
cutting unit will lift up and the blades stop rotating.
Secure the cutting unit if necessary using the mechanical
lifting lever.
Lowering the Unit (Mowing Position)
If the cutting unit is secured in the transport position using the
mechanical lifting lever, move the mechanical lifting lever to
the cutting position.
Move the hydraulic lifting lever forwards to engage the cutting
position. The unit is lowered and the blades begin to rotate.
In order to ensure that the hydraulic cylinder is in the outer
position, hold the lever in the forward position for a half to one
second.
Mechanical Lifting Lever for Cutting
Unit
The lever is used as a backup lever to put the cutting unit in
either the transport or mowing position when hydraulic
pressure is unavailable. It can also be used to mechanically
secure the cutting unit in the transport position.
The lever must be used when starting the engine, if the
engine stopped with the unit in the mowing position, in order
to raise the unit so that the start lock circuit is disengaged.
When the lever is moved to the transport position, the blade
brake is automatically activated so that the blades stop within
about 5 seconds.
Transport position
If the lever is pulled backwards the unit is raised and the
blades automatically stop rotating (transport position).
Mowing Position
If the lock button is pressed in and the lever is moved forwards
the unit will be lowered and the blades will automatically start
to rotate (mowing position).
If this does not happen it is probably because the unit has
been lifted with the hydraulic lifting lever. Lower the unit to the
mowing position with the lever for the hydraulic lift.
Cutting height adjustment lever
The cutting height can be adjusted to 7 different positions with
the cutting height lever.
It is important that the air pressure in both front wheels is
equal, 60 kPa/8.5 PSI, to produce an even cutting height.
