them. It is essential that the accident

prevention regulations are observed.

• There are two locations for hitching the mower to the

tractor.

The lower link pins are of cat. II + cat. III.Normally the

mower is attached to the tractor in position 1 (cat.III).

For wider tractors or when working in combination with a

front-mounted mower (of abt. 2.8 to 3.2 m working

width), the mower should be attached to position 2.

In addition the lower hitch pins (1) can be installed in

position 1 or 2 for a lateral offset of X = 50 mm.

3.2.2 Coupling

• Secure the lower links (1) to the hitch points provided

for this.

• Attach top link (2) to the top hole of the 3-pt

headstock.

The lower link arms on the tractor must

be fixed with the limiting chains or rods

to prevent the machine swinging out

during transport or operation.

If the lower links (1) are equipped with

quick release hitches, the following

points must be observed:

• In particular in headland position,

high forces occur in the lower linkage

bolts (3), which act upwards in the left-

hand side hitch.

This is why the hitches must be in very

good condition.

• Additionally, after coupling, the

hitches must be secured against

accidental opening using the locking

holes (4) provided.

3.2.3 Axle load

The permissible values for total weight,

axle and tyre load must not be exceeded

as a result of machines being hitched to

the front and rear 3-pt linkage of the

tractor. If a rear-mounted machine is

installed, the load on the tractor front

axle must never be inferior to 20% of the

tractor’s dead weight.

Be sure that these requirements are

fulfilled before moving on.

Preparing for Operation

ECQ00013

The disc mower is be operated with a maximum PTO shaft speed of 540 rpm.

The PTO shaft must only be fitted and removed when the PTO shaft and engine are

switched off and the ignition key has been removed.Secure the tractor against rolling

away. Be sure that the locking device of the PTO shaft locks into engagement.

Secure the guard tubes to prevent them rotating with the shaft.

3.3 PTO Shaft

3.3.1 Adapting the PTO shaft

• Push the PTO shaft (1) onto the tractor PTO shaft

and secure

• Secure the protective tube using the retaining chain

(2) so it does not rotate with the shaft

• The PTO shaft for the conditioner drive is mounted

with the friction clutch (1) towards the gearbox and

the free-running end (2) towards the conditioner.

Attach the retaining chain (3) to the mower.

3.4 PTO shaft for the conditioner drive

Check the swivel space and the free

movement space for the PTO shaft. If

the PTO shaft touches the tractor or

the attachment, this can cause

damage.

• Hold the PTO shaft halves (1) and (2) next to each

other

• Check the overlap of the attachment and protective

tubes

• Shorten profile and shielding tubes so that in its

shortest operating position the PTO shaft can be

pushed together by at least 150 mm. (This clearance

is required to be able to push the PTO shaft together

if the spring-loaded breakaway device is actuated).

• Adapting the length of the shaft is described in detail

in the PTO shaft manufacturer's operating instructions

Bleed the friction clutch (1) before the

first operation and then once a year

before the harvesting season (see

chap. Start-up after winter storage

„Friction clutch“)

Preparing for Operation

3.5.3 Jack Stand

Both a double-action and a single-action control unit are

required on the tractor to operate the machine.

Double-action control unit (1) (red):

• Raises and lowers the mowing unit from the transport

position to the headland position or vice-versa.

Single-action control unit (2) (yellow):

• Raises and lowers the mowing unit from the working

position to the headland position or vice-versa.

When the hydraulic hose is connected,

the hydraulic control device must be in

floating position or in the “Lower”

position.

3.5.2 Connecting the hydraulic hose

ECQ00005

Fold the parking support (2) in to the working position of

the disc mower and lock it in place with the bolt (1).

Before placing the machine in operation,

make certain the parking support is

folded in and secured with the bolt!

3.5 Hydraulic

3.5.1 Special safety instructions

• When connecting the hydraulic hoses

to the tractor, the hydraulic system on

both sides must be free from pressure!

• When tracing leakages, use suitable

aids and wear protective goggles to

prevent injury.

• Fluid escaping under high pressure

(hydraulic oil) can penetrate the skin

and cause serious injury! If such

injuries occur, consult a doctor

immediately. Danger of infection!

• Release the pressure before

disconnecting hoses and before any work

is carried out on the hydraulic system.

• Check hydraulic hoses regularly, and

replace any damaged or worn hoses.

Replacement hoses must conform to the

mower manufacturer’s technical

specifications.
