2 Product description
This chapter:
•gives a comprehensive overview of the machine design.
•provides the designations of the individual assemblies and operating elements.
Please read this chapter in the immediate vicinity of the machine if possible, thus acquainting yourself
with the machine in the best possible way.
The machines illustrated in these operating instructions partly include optional extras which are
available at extra cost.

2.2 Chassis
Depending on the machine's equipment, the chassis consists of:
•a Bogie tandem chassis
 with passive steering
 with forced steering axle (only with bottom linkage)
 with dual-line compressed-air brake system and mechanical ALB regulator
 with hydraulic brake system
•a tandem or tridem chassis with hydraulic balancing system:
 with passive steering
 with forced steering axle system
 with hydro-pneumatic suspension
 with dual-line compressed-air brake system and hydraulic ALB regulator
 with hydraulic brake system and emergency brake valve
2.2.1 Bogie tandem chassis
3-leaf parabolic springs serve as a compensating rocker arm in the bogie tandem chassis.
In case of bumps, the large swing paths ensure an even load distribution onto both axles.
2.2.2 Tandem /Tridem chassis with hydraulic travelling height adjustment
The hydraulic travelling height adjustment:
•ensures dynamic axle load compensation
between the axles due to the large
compensating paths of the hydraulic
cylinders, thus constantly ensuring an even
load on the axles.
•ensures anti-roll stability on sloping ground
and during fast cornering.
•activates the hydraulic ALB regulator of the
dual-line compressed-air brake system.
In the hydraulic chassis with separate travelling
height adjustment for the right-hand and left-hand
machine side, the balancing between the wheels
on each side is carried out by four or six hydraulic
cylinders (1).

2.2.2.1 Tandem / Tridem chassis with hydro-pneumatic suspension
The hydro-pneumatic suspension:
•ensures higher driving comfort due to active suspension.
•permits travelling speeds of > 40 km/h.
•protects material and tyres.
One nitrogen accumulator on each side ensures the axle suspension and the damping of the machine
on the individual wheels.
The axle suspension can be switched on and off via the stop-cock or via the control set.
The axle suspension is active with the road travel mode switched on, the axle suspension is disabled
with the road travel mode switched off (only with ISOBUS control).

2.3 Drawgear
Depending on the design of the tractor's coupling
device, the drawgear (1) can be coupled to the
tractor by means of a top or bottom hitch.
Drawgear options for bottom linkage:
•drawbar lug (hitch ring) for a tow-hook
(hitch hook) or a draw pin (Piton-Fix) or
•shell K80 (2) for a ball-type coupling 80.

Drawgear options for top linkage (optional extra):
•a drawbar lug 40 (3) for a bolt-type
coupling
•a shell K80 (2) for a ball-type coupling 80.

•a drawbar lug (export) (4) for a tow-hook or
a draw pin.

The towing eye (1) for rescuing is mounted at the
rear on the frame.

2.5 Brake system
Depending on the machine’s equipment, the service brake system consists of:
•a dual-line compressed-air brake system,
•a hydraulic service brake system (only available for export),
•a combination of dual-line compressed-air brake system and hydraulic service brake system
and a parking brake.
The applied parking brake acts independently of the service brake system and secures the unhitched
machine against accidental rolling.
2.5.1 Dual-line compressed-air brake system
The brake system consists of:
a braking axle with a dual-line compressed-air brake system and parking brake for an
admissible maximum speed of 25 km/h, 40 km/h or 60 km/h. The service brake acts on all
wheels.
an automatic load-sensitive brake pressure regulator (ALB regulator). The ALB regulator
automatically controls the required braking force depending on the loading condition of the
hitched machine.
The brake system acts on the braking axle/s.
Observance of the maintenance intervals is indispensable for proper
functioning of the dual-line compressed-air brake system.

2.5.2 Dual-line compressed-air brake system with mechanical automatic load-
sensitive brake (ALB) regulator
WARNING
Risk due to insufficient braking ability of the machine if the
mechanical ALB regulator has not been properly set!
The setting dimension (L) at the ALB regulator must not be modified.
The setting dimension (L) must correspond to the value indicated on
the ALB plate.

(7) Operating element for release valve (can
only be actuated in uncoupled condition):
•Push in as far as it will go and the service

manoeuvring the unhitched machine
•Pull out as far as it will go and the machine
is braked again by means of the system

2.5.3 Dual-line compressed-air brake system with hydraulic automatic load-
sensitive brake pressure (ALB) regulator
WARNING
Risk due to insufficient braking ability of the machine if the
travelling height of the hydraulic levelling system has not been
properly set!
The hydraulic levelling system properly triggers the ALB regulator
only with the travelling height properly set.
