SPECIAL SAFETY RECOMMENDATIONS

1. Use a tractor equipped with an enclosed cab with windows made of safety glass and kept closed. It is

recommended to fit polycarbonate screens inside the tractor safety cab's side and rear windows or to install

mesh guards on the exterior of them.

2. Stay a safe distance away from the mower when discs are rotating.

3. For safe machine operation, it is imperative that cutting tools be fitted in accordance with the manufacturer’s

recommendations. Use only the tool outfit supplied with the machine.

4. Each time before using the mower, inspect condition of cutting elements (knives, discs). Replace any

missing, worn or damaged cutting elements immediately. Use only genuine KUHN spare parts.

5. To avoid creating dangerous out of balance forces, always replace missing, damaged or worn knives in

pairs.

6. When replacing knives or discs, systematically inspect their securing elements as per the manufacturer’s

recommendations.

7. Regularly inspect the disc mower’s protection cover. Worn or damaged protection covers must be replaced

immediately.

8. Protection devices (such as guards, shields etc.) are intended to prevent stones, rocks or other foreign

objects from being projected. They also prevent access to the machine’s danger zones. Therefore, it is

imperative that protection devices are put in place and properly secured each time before using the

machine.

9. Crushing and shearing zones which could cause serious bodily injury when changing the machine from

transport to work position and vice versa may exist. To prevent possible injury, be extra careful when

maneuvering and ensure that everyone is at a safe distance away from the machine.

10. Never tow the machine at speeds higher than 25 km/h (15 mph).

11. PTO drive to the mower must never be engaged unless the cutterbar skid shoes are in contact with the

ground and the protective cover is folded down.

12. Ground of the pastures to be mown must be free of foreign objects.

13. Even when the machine is used in accordance with it purpose, objects may be projected. It is therefore

imperative that everyone be kept away from the danger zone, that extra care be taken and that extra

precaution (such as safety indicators) be taken when mowing pastures alongside roads or near public areas

(parks, schools etc.).

14. Never mow in reverse.

15. When disengaging the PTO drive, moving parts continue to rotate for some time. Wait for all moving parts

to come to a complete stop before approaching the machine.

16. If an obstruction is hit, stop the tractor immediately, disengage PTO drive, turn off engine, remove ignition

key and wait for all moving parts to come to a complete stop.

Check the entire machine for any damage before resuming work.

ASSEMBLY INSTRUCTIONS

The ALTERNA Mower Conditioner is shipped fully

assembled, except for the primary PTO shaft (1) and

the work wheels (2) which are unassembled to reduce

bulk. These loose components are attached to the

metallic drawbar support (3).

Drawbar support (3) has been specially designed for

improved ease of securing the unit in place and

facilitated handling and transporting for delivery.

1) Remove primary PTO shaft (1). Remove the

work wheels (2) and fit them on the work wheel

hubs.

Work wheels are to be fitted with the

valves on the outboard side of their

hubs.

Tighten wheel nuts to 15 daNm

(110 ft.lbs).

2) Remove drawbar support (3) as follows :

- Connect the two tractor draught arms to the

coupling yokes (4) by means of hitch pins (5).

- Lift the drawbar support (3) off the ground by

activating the tractor hydraulics.

- Remove pin (6) and lock parking stand (7) into

its vertical position using handle (8).

- Lower the tractor draught arms so that the

weight of the drawbar is supported by parking

stand (7).

- Remove the two pins (5) and take off the

drawbar support (3).

3) For reduced bulk, the left rear light support ele-

ment has not been installed in its final position.

Remove bolts (9), untighten bolt (10) and straighten

up the light support until its mounting hole lines up

with the tapped hole of the chassis. Reinstall bolts

(9) and torque both bolts to 2 - 3 daNm (15 - 22

ft.lbs).

NOTE: The ALTERNA 400 are supplied with one

right deflector (11) and one left deflector to

be mounted inside the hoods using the origi-

nal hardware (12) as shown on photo

opposite.

These deflectors enable forming even swaths

over the whole swath width when working in

slightly or moderately dense crops.

They must not be fitted for work in dense

or very dense crop.

- 12 -

ATTACHMENT TO THE TRACTOR

- Back the tractor up to the mower conditioner and

attach lower links (5) to the interior of the pivoting

yokes (4) with hitch pins (3). Secure the hitch pins

with linchpins (1).

For category 2 tractors use 28 mm hitch pins (3). For

category 3 tractors use 37 mm hitch pins (3) and

spacers (2).

- Activate the tractor hydraulics to completely raise

lower links (5).

- Fold up parking stand (6) and lock in place using

handle (7).

- Secure the tractor lower links laterally using check

chains or linkage stabilizer bars provided at the same

time making sure that the tractor PTO and machine

input shaft are lined up in the vertical plane.

Fitting the primary PTO shaft :

Connect the primary PTO shaft’s flanged yoke (8) to the

Gyrodine slip clutch. Secure in place using 6 self-

locking bolts (9) (M 12 x 25).

Tighten to a torque of 9 daNm (66 ft.lbs).

Make sure bolts are torqued to 9 daNm (66 ft.lbs).

To avoid accidents which could be serious, make

sure that the guards are always correctly in place

and secured with the safety chains. The safety

chain on the machine side must be attached on the

guard of the torque limiter. All worn or damaged

guards must be replaced immediately.

- 13 -

ATTACHMENT TO THE TRACTOR

Make sure the PTO shaft length is correct for the

tractor being used.

1) Activate the tractor hydraulics to line up the

tractor PTO and the machine input shaft in the

horizontal plane.

2) Slide the other half PTO shaft (without torque

limiter) onto the tractor PTO and align both half

PTO shafts side by side. If there is excessive

overlap, mark and shorten the hatched portions

of the transmission tube keeping a safety clear-

ance of 10 mm (0.5") between the ends of the

tubes and the yokes.

- Bevel and debur transmission

tubes. Remove all steel chips and

filings. Grease the inside of the

outer transmission tube.

- Shorten the guard tubes by the

same length as the transmission

tubes, as shown in the opposite

drawing.

- For your safety, there must be a

minimum tube overlap of 180 mm

(7") when the PTO shaft is in its

maximum extended position.

- Make sure the PTO shaft is con-

nected to the 1000 min-1 tractor

PTO.

3) All machine operations are controlled by the

tractor’s two double acting directional valves.

a) Connect hydraulic hoses (1) to the outlets of

the first directional valve, which will be re-

ferred to as DE1. Activating DE1 raises and

lowers the cutterbar.

b) Connect hydraulic hoses (2) to the outlets of

the second directional valve, which will be

referred to as DE2.

c) Carefully fit and cable the pre-cabled female

socket (5) (see electric lay-out, connections

and schematic).

d) Plug terminal (4) into the installed female

socket.

- Activating DE2 on its own sets the machine to

the right or to the left of the tractor.

- Activating DE2 and simultaneously pressing

thumb switch (3) raises and lowers transport

wheels.

- 14 -

DETACHING THE MACHINE

Machine must be parked with the weight of the

tongue resting on the parking stand.

When parking the machine :

- Fully raise the tractor lower links.

- Pull out lock handle (1) which secures parking

stand in the horizontal position (the parking stand

lowers on its own).

- Move the lower end of the parking stand back and

forth so that it automatically locks into the vertical

parking position.

- Lower the tractor lower links until yokes (2) are

relieved of the drawbar’s weight.

- Block the wheels with wedges if the area is not even

and level.

- Uncouple the tractor draught arms, the check

chains and the PTO shaft.

Safety chain (3) supports the primary PTO shaft

when the machine is disconnected from the tractor.

In this position the PTO shaft is not in contact with the

ground, thus avoiding deterioration due to dust and

dirt. Holder (4) provides effective protection to the

hydraulic quick couplers.

Place electric terminal (5) in its support and house

the remote control handle (6) with its terminal in the

storage box provided and close the lid.

Park the machine on level ground

when it is in the transport position.

- 15 -

Always ensure that nobody is near

the machine pivoting zone

(hatched area on the drawing

opposite) before and while chang-

ing the machine from the road

transport position to the work po-

sition.

Changing the machine from the road

transport position to the work

position.

Before starting this switch over, double check that

the tractor lower links are completely raised.

When operating on sloping ter-

rain and to avoid that the ma-

chine goes off course, activate

DE1 to extend the cylinders for

the work wheels so that they stay

as near to the ground as possible.

1) Activate DE2 until machine and drawbar are at a

90° angle to each other.

2) Activate DE1 to fully extend the cylinders for the

work wheels.

3) Press thumb switch and at the same time shift

DE2 in the same direction to raise the transport

wheels.

TRANSPORT TO WORK POSITION

- 16 -

4) Operate DE2 to position machine to the left or the

right side of the tractor.

5) Move slowly forward until the work wheels are

aligned in the same direction as the tractor wheels.

6) Operate DE1 to fully retract the work wheel

cylinders and lower the cutterbar onto the ground.

7) With the tractor’s hydraulic 3-point lift, position

the Girodyne head in order to set the hitch pins at

a distance of 700 mm/ 2’4" from the ground.

Hook one end of the check chains (R) to the hitch

brackets (C) by means of the shackles (S) and

attach the other side to the tractor’s top link yoke

by means of the top link hitch pin (A).

Lower the 3-point lift. The attachment is correct

when the underside face (I) of the tongue is

approximately horizontal and the lower hitch pins

are at a distance (H) of around 650 mm/2’2"

from the ground when the check chains (R ) are

taut.

The cutterbar must rest on the

ground before engaging the PTO.

Never mow in stony or rocky

grounds.

TRANSPORT TO WORK POSITION

- 17 -

Changing the machine from the work

position to the road transport position

It is advisable to first position machine to the right-hand

side of the tractor by shifting DE2.

1) Raise tractor lower links completely.

2) Activate DE1 to fully extend work wheel cylinders.

3) Press thumb switch and at the same time operate

DE2 to lower the transport wheels.

Note : Both transport wheel cylinders may not oper-

ate at the same speed. To assure that both

cylinders are fully extended, keep the valve

shifted for a few seconds after the front

transport wheel has closed up against its

stop. Then return DE2 to neutral.

4) Shift DE1 in the opposite direction to lower the

unit onto the transport wheels.

When operating on sloping ter-

rain and to avoid that the ma-

chine goes off course, keep the

work wheels as near to the ground

as possible.

WORK TO TRANSPORT POSITION

While changing the machine from

the work position ot the road trans-

port position:

- Stop tractor P.T.O. and wait for

rotating discs and rotor to stop.

- Always ensure that nobody is

near the machine pivoting zone

(hatched area on the drawing

opposite).

- 18 -

WORK TO TRANSPORT POSITION

5) Shift DE2 in the same direction to align the chassis

with cutting/ conditioning unit under the drawbar.

If the machine does not pivot when

shifting DE2, then the transport wheel

position sensor has not been closed

by the rear transport wheel. Repeat

procedure described in points 2 and

3 to eliminate the fault.

6) Close the swathboards completely in order to

reduce the machine’s transport width.

Before transporting the machine ensure that :

a) The cutting/conditioning unit is correctly locked

under the drawbar.

b) Work wheels are fully raised (cylinder rods com-

pletely retracted).

c) The 4 hydraulic hoses are unplugged and the

quick couplers are housed in their support.

d) The electric terminal is unplugged so that the

tractor batteries are not run down.

Always check that the rear lights

and indicators are clean and func-

tioning correctly before going on
