PRESENTATION
Cutting unit
R 422 Ts AWD can be equipped with two different cutting units. Combi 112 and Combi 122
The
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.
