I. Foreword

Dear customer,

We thank you for the trust you have placed in us by

purchasing this machine.

When you received this machine, the dealer should

have given you instructions for the operation,

maintenance and adjustment of the machine.

However, this brief introduction to the machine can

not replace a detailed acquaintance with the different

tasks and functions of the machine and the proper way

of treating it.

These operating instructions are designed so that you

are extensively informed of the activities required in

each area, from commissioning and operation to the

maintenance and care of the machine. The structure of

the individual chapters in the text and illustrations

corresponds to the sequence of work procedures when

you use the machine.

Read these operating instructions carefully before you

use the machine, and pay special attention to the

safety instructions.

Important: To avoid accidents and to ensure

maximum results, no alterations may

be made to the machine without the

manufacturer´s permission. Similarly,

the machine must only be used under

the conditions prescribed by Krone.

All information, illustrations and technical information in

the operating instructions represent the latest status at

25.Power operated parts (e.g. by hydraulics) contain

danger points which can cause injury by bruising and

grazing!

26.Before leaving the tractor, rest the mower on the

ground, switch off the engine and remove the ignition

key!

27.Make sure that no personnel go between the tractor

and the implement unless the tractor is protected from

rolling by the parking brake and/or wheel blocks!

3. Attached Equipment

1. Special care is required when the implement is being

connected to the tractor or disconnected from it!

2. The implement must only be coupled to the

appropriate fittings (e.g. the 3-point connection), and

they must be so secured (transport, operation) that

unintentional lifting or lowering of the implement is

not possible.

3. When connecting the three point linkage, it is

absolutely essential that the hitching categories of

the tractor and attachment (e.g. power take-off shaft

speed, hydraulics) are matched!

4. When operating the external controls for three-point

connection, make sure that nobody goes between

the tractor and the implement (danger of injury)!

4. Power Take-Off shaft Operation

1. Only the P.T.O. shafts prescribed by the manufacturer

may be used!

2. Both male and female guard tubes and cones of all

P.T.O. shafts must be fitted and in good condition!

3. Observe the tube overlap prescribed for P.T.O. shafts

in transport and operating position!

4. Before installing or removing the P.T.O. shafts, make

sure to turn off the power take-off shaft and the engine,

and remove the ignition key!

5.When using P.T.O. shafts with overload or free wheel

Liquid that squirts out at high pressure (hydraulic oil) can penetrate the skin and cause severe

injuries!

If injuries occur, consult a doctor at once! Danger of infection!

Connecting the hydraulic hose

Control cable

The control cable must be so positioned that it can not cause any accidental movements in any

transport or working positions and does not come into contact with the tractor tyres.

The control cable for the releasing function "Transport

position" should be fitted at a suitable position on the

tractor.

Depressurize the tractor hydraulic system. Insert the

hydraulic hose into the hydraulic coupling of the control

valve.

AMS-3-002

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.

Release the linch pin (1) and washer (2) from the upper

securing bolt. Push the compensation spring (3) onto the

securing spring after the distance sleeve. Secure it with

the washer and linch pin.

The procedure for shortening the PTO

shaft can be found in the operating

manual of the PTO shaft manufacturer.

To adapt the PTO shaft, the halves of the PTO shaft (1)

and (2) are held together in the shortest operating

position in order to determine the overlap of the profile

tube and the protective tube.

Adapting the PTO shaft

• It is forbidden for persons to ride on the disc mower.

• Mount the lighting and check that it works.

• In transport position, always close the hydraulic shut-off valve on the hydraulic cylinder.

• When the mower is in transport position, it is important to remember that the vehicle has a

greater overall height!

2.4 Transport position

To raise the mower, pull up the locking device (2) with

the control cable (1) from the tractor.

Activate the tractor’s control valve for the hydraulic

cylinder. The mower then lifts up into transport position.

2.7 Driving on the headlands

To adjust the lowering speed of the mower unit, an

adjustable throttle (1) is attached to the shut-off valve

(2) of the hydraulic cylinder (3).

For driving on the headlands, the mower

is only raised or lowered by the hydraulic

cylinder of the mower unit. The locking

device for lifting the mower unit must not

be activated.

To ensure simple fitting of the disc mower to tractors

with a tail hook, it is advisable to dismantle the rear

compensation spring. To do so, with the disc mower

only in transport position, pull out the linch pin (1) on

the upper retaining bolt (2) of the rear compensation

spring. Take off the washer. Pull the compensation

spring off the upper retaining bolt and lay it on the

resting bracket (4).

Open the shut-off valve (1) on the hydraulic cylinder (2)

of the disc mower (cf. the dotted position). Operate the

control valve on the tractor to lower the mower unit

slowly.

2.8 Disassembly of the disc mower

•Only rest the disc mower on a level and firm surface.

engine switched off and the ignition key removed. Secure the tractor against

unintentional operation and rolling away.

• Always check protective devices for damage before operation. Replace damaged

protective devices immediately. Risk of injury!

• Prop up the cutterbar when raised. Never stand under a suspended load!

• Safe operation is only guaranteed if the cutter blades are fitted according to the

instructions.

• Always check the mower unit for damaged, missing or worn cutter blades before

operation. If necessary, replace cutter blades. The same applies for retaining

components.

• To prevent unbalanced rotation, only replace missing or damaged cutter blades as

complete sets.

• Never fit cutter blades with different levels of wear to one drum/disc.

• Whenever you change cutter blades also check retaining components and replace

them if necessary.
