8.1 Agregation to a tractor
•
The machine can be connected only to a tractor, whose curb weight is identical or higher than
the overall weight of the connected machine.
•
The machine operator must observe all generally valid regulations of work safety, health
protection, fire safety, and environmental protection.
•
The operator may connect the machine exclusively to a tractor that is equipped with a rear
three-point suspension and a functional undamaged hydraulic system.
•

sockets ISO 12,5
** control circuit for levelling discs
Circuit pressure 200 bar, 2 pcs of quick-coupler
sockets ISO 12,5
* Recommended towing means, the real towing force may significantly vary according to the processing
depth, soil conditions, land slope, working body wear and adjustment
** Optional equipment
•
The machine is attached to a three-point suspension TPS as per Tabl.
•
The machine aggregated with the tractor changes the distribution of the weight to the
individual axles of the tractor. The weight of the front axle is reduced and therefore the
controllability gets worse. It also affects braking properties.
When connecting, no persons may stay in the space between the tractor and the machine.
