The self-propelled high-performance mower conditioner is a self-propelled work machine with
three disc mowers and integrated mower conditioners. The self-propelled high-performance
mower conditioner is intended for use in agriculture. The self-propelled high-performance
mower conditioner is used to mow various living grasses and legumes (from the initial stage to
the end of the photosynthetic process).
The three mowing units can be used individually or together, thereby making it possible to
adjust the working width as required. The integrated mower conditioners accelerate the drying
process of the mowed crop.

3.6 Autopilot
1Autopilot must only be used for its intended purpose. It must only be used in open fields, off
public and semi-public roads, away from open areas frequented by people and far away
from any persons that could be endangered. They must only be used for their intended
purpose: - Automatic guide of the machine by GPS (Global Positioning System).
2Before placing the autopilot in service, check the functionality of safety elements that can be
checked and make a visual inspection of all the components.
To do this, the user should proceed as follows:
• Check switching off of the autopilot when the steering wheel is moved and the seat
switch engages
• Check for proper operating condition - i.e. free of mechanical damages and leaks
3When autopilot is in operation, there must be on one within 50 m of the machine in any
direction.
4The operator is not permitted to leave the driver's cabin of the machine while autopilot is in
operation.
5While the autopilot is in operation, the driver must regularly check the direction in which the
machine is moving and its travel path to be able to take over manual control of the machine
immediately if obstructions or interruptions come up in the vehicle's path.
6After autopilot has been in operation and before leaving the field, autopilot must always be
switched off on the autopilot release switch on the console.
7Manipulating safety-related elements of the autopilot is prohibited, as is making changes to
the hydraulic, electrical or electronic components.
8The autopilot should only be installed by an authorised service centre.

3.8 Hydraulic system
1 The hydraulic system is pressurised!
2 When connecting hydraulic cylinders and engines, make sure that the hydraulic hoses are
connected correctly!
3 When connecting the hydraulic hoses to the mower-conditioner hydraulics, take care that
the hydraulic system is depressurised both on the tractor side and on the device side!
4 When functions are connected hydraulically between the mower-conditioner and the
accessory equipment, connecting parts should be identified so that faulty operation is
excluded! If the connectors are interchanged, the functions will be reversed (e.g.
raising/lowering) - Risk of accident!
5 Check the hydraulic hose lines at regular intervals and replace them if damaged or worn!
The new hoses must fulfil the technical requirements set by the manufacturer of the
implement!
6 When searching for leaks, use suitable aids to avoid the risk of injury!
7 Liquids escaping under high pressure (hydraulic oil) can penetrate the skin and cause
serious injury! Seek medical help immediately should injuries occur! Danger of infection!
8 Before working on the hydraulic system, depressurise the system and switch off the engine!
