aTTaCHing TO THE TraCTOr

Preparations on the tractor

General

Please observe the power range limits of the tractor being used.

Wheels

- Air pressure in the tractor’s rear tyres when ploughing should be 0.8

bar.

- Under difficult operating conditions additional wheel weights can be

advantageous. See the tractor manufacturer’s operating manual also.

Ballast weight

- Sufficient ballast weights are to be stacked on the front

of the tractor in order to guarantee steering and braking

capabilities.

- At least 20% of the tractor’s tare weight on the front axle.

Lifting gear

- Left and right lifting struts (4) must be of equal length.

Adjust using adjusting device (3).

- If the lifting struts on the lower link can be pinned variously, then select

the back position (H). In so doing the tractor’s hydraulic unit will not be

heavily loaded.

- Position (2) the upper link (1) according to the tractor manufacturer’s

information.

Setting-up for transportation

- Fix the lower link with the struts (5) so that the attached implement cannot

swing out during transportation.

- The hydraulic’s operating lever must be secured against lowering.

- Do not transport in the „ON-LAND“ position

Setting-up for ploughing

- Set the struts (5) so that the greatest possible sideways swing range

exists.

Hydraulic control on the lifting gear

Control position:

For mounting and dismounting the implement and for transportation.

The control position is the normal setting for the lifting gear hydraulics.

The mounted implement remains at the height (= position) set by the servo-

valve (ST).

Pull control, mix control:

Ploughing occurs with of one of the two operating modes. See chapter

„OPERATION“ for description.

Removal from tractor

Hint: The shear points are hardened so when set down onto hard surface

(stone, concrete, etc.), risk of breaking exists. Therefore lower the

shear points onto a suitable support (wooden board)!

- Turn plough frame to working position and park the implement on

stable and even ground.

- Move the control lever (ST)

back and forth several times

to reduce pressure in the

hydraulic lines.

Attaching to the tractor

Safety advice:

See supplement A1, Pt. 8a-h

- Switch tractor’s hydraulics to control position.

- Attach implement to lower link and secure with linch pin.

Note

The attaching frame can be positioned horizontally by turning the

tilt spindle (11).

Doing this enables an easier coupling to the lower link.

Then turn the tilt spindle (11) back. See chapter „OPERATION“

also.

Pin upper link (1)

- Pin upper link (1) so that the attachment point (P1) on the plough

during operation is somewhat higher than the attachment point (P2)

on the tractor.

Securing lower link

If the tractor’s hydraulic control

is to be steered over the lower

link, then the upper link should

be positioned in the slot (LL) on

the attaching frame.

Securing upper link

If the tractor’s hydraulic control

is to be triggered over the upper

link, then both the (RL) borings

on the attaching frame are to be used.

- Couple hydraulic hoses to the tractor.

Fine setting (Measurement F)

Fine setting is tuning the plough to the tractor being used and is therefore

only to be carried out once.

In so doing, the fine setting spindle is set at the determined measurement

(F).

- Take the measurements (A) and (B) on the lower linkages and determine

the intersection point according to the table for a Kat. II.

The measurements (A, B) must always be taken from ball centre to ball

centre.

- The position of the intersection point between the diagonal lines on the

table is the setting (F).

Table for Katt. II

Kat. II = 825 mm

W = 80 mm

Example:

A = 416 mm

B = 931 mm

W = 80 mm

(W = 200 mm)

The intersection point lies between lines "306" and "308".

Therefore the intersection point is 307 mm.

F = 307 mm

Setting the adjusting spindle

- Remove bolts (12).

- Set the adjustment spindle to the determined measurement

(F).

- Replace bolts (12).

Setting the plough to the tractor using

"Servomatic"

„SERVOMATIC“ enables the optimum adaption of plough to tractor.

The following setting controls should be carried out in order.

1. Fine setting (F)

- Check setting measurement for fine adjustment spindle (F).

See chapter "PRESETTING THE PLOUGH".

2. Furrow width setting of the first ploughing component

(backfurrow)

The furrow width (S2) of the first ploughing component is set by turning

the spindle (VF).

Furrow width (S1) to narrow

- turn spindle (VF) longer

Furrow width (S2) to wide

- turn spindle (VF) shorter

Furrow width (S2) correct

- Spindle is correctly set according to table.

See chapter "PRESETTING THE PLOUGH“

Incorrect setting

The drawing line does not run through the mid-point of the tractor’s rear

axle. Tractor is drawn into already ploughed area during ploughing. This

can only be compensated by steering in the opposite direction.

- Turn spindle (ZP) longer

See chapter "PRESETTING THE PLOUGH“

3. Setting the drawing point (Z)

Correct setting

The drawing line (ZL) runs through the mid-point (M) of the tractor’s

rear axle. No side pull arises from the tractor.

The plough is easy to pull.

- Spindle (ZP) is set according to the table.

Turning the plough over

Beware!

Nobody is to stand within the swinging range during turning.

Turning procedure is only to be actuated from the tractor cabin.

The plough must be completely raised to turn.

The automatic reversing gear enables the whole turning procedure to

be carried out through only one single switch position on the control

unit (ST). (Oil quantity necessary: 40 – 50 l/min)

Turning procedure with a double-action cylinder

- Switch control unit (ST) to lift (h).

The plough is turned 180¯.

- Switch control unit (ST) to neutral (O).

After some 5 seconds another turning procedure can be effected.

Setting the plough gradient (11)

The plough should sit as vertical (90°) as possible to the ground during

ploughing. This position is obtained by turning both spindles (11) as

described below.

- Lift plough 5 - 10 cm

- Actuate control unit (ST) briefly.

The plough turns slightly away from the stop spindle (11).

- Set the gradient using the spindle (11).

- Turn plough back to stop again.

- Proceed with ploughing and check whether the plough sits more vertically

(90°) to the ground through the new setting.

Ploughing with hydraulic control

So that the hydraulic control functions properly, the following must

be observed.

- Position upper link (1) so that the attachment point (P1) on the

plough during operation is somewhat higher than the attachment

point (P2) on the tractor.

Pinning the upper link

LL, RL = Pinning position for securing lower link

RL = Pinning position for securing upper link

Details see chapter „ATTACHING TO THE TRACTOR“.

- During operation the plough should lie lengthwise as parallel as

possible to the ground surface.

- The working depth is set with the lifting gear via the servo-valve

firstly.

Depending upon the hydraulic control model, varying ground

resistance when ploughing is passed on to the control servo-valve

via the upper link (1) or both the lower links. The relevant impulse

is then converted causing the lifting gear to lift or lower.

An example: Securing upper link

The plough penetrates deeper into the ground.

This causes the pressure on the control servo-valve via the upper

link to become greater.

As a consequence, the control valve remains switched to lift until

the set working depth is reached again.

Note:

Follow the tractor manufacturer’s operating manual also.

OPERATION

ON-LAND Ploughing

What does "ON-LAND-Ploughing" mean?

• Notractorwheelsinthefurrows

- All wheels travel on unploughed ground.

Advantages of an "ON-LAND-Plough"

• Ground care with "ON-LAND" ploughing.

No tractor wheels in furrows to compress and knead the

ground. Less tractor wheel slippage as with conventional

ploughing in wet conditions.

• Greater swing range

This makes even travelling on unploughed ground with

dual wheels possible.

• Boundary ploughing possibility

To swing the plough away from ground already ploughed

(antiON-LAND position). This enables accurate

ploughing right up to a boundary.

• Conventional Ploughing

The plough can be centred behind the tractor =

conventional ploughing with wheels in the furrows.

KP = conventional ploughing

OP = "ON-LAND" ploughing

Conventional ploughing

Ploughing with wheels in the furrows

Swing plough to behind centre of tractor using hyraulics.

Converting to conventional ploughing

Safety points

• Conversion to be carried on rm level ground

only

• Do not enter the area underneath a raised

plough

• When converting stay off the raised plough

1. Raise plough slightly

- use tractor's lifting gear

2. Pin spindle in (KP) position

- secure bolt with linch pin

3. Re-set drawing point (ZP)

When overloaded the shear bolts break (30) and the ploughing component swings away and up.

- Remove the rest of the shear bolt.

- Loosen hexagonal bolt (31).

- Swing ploughing component back into the working position.

- Insert new shear screws and retighten both bolts.

Take note!

Only use genuine shear bolts (see spare parts list) with the corresponding dimension and quality. Under no circumstances

SERVO NOVA

Fully automatic "Non-stop" overload

safety

For grounds that are difficult to plough, with stones or

other foreign bodies, it is recommended to use the fully

automatic overload safety.

With the SERVO-NOVA plough, every plough body

is secured individually against deteriorating by hydro-

mechanical means.

When driving over obstacle, the plough body can swing

to either side. There is no need to stop the tractor. The

plough body swings back to working position by itself.

In addition to the fully automatic "Non-stop" overload

safety, all plough bodies are protected by a shearbolt.

Be advised!

No welding, soldering or mechanical work

may be performed on the gas container.

Changing the pressure in the gas tank

This operation may be performed only

by the customer service or a special-

ised workshop.

To reduce or increase the preload

pressure, you need a special filling

and verification device.

1. Release pressure:

a) Take out the plastic cover.

- Take out the lead mould plug (if available) in the gas

filling plug (44) with the help of a sharp tool.

b) Loosen the gas filling plug (44) only slightly.

c) Screw on the filling and verification device.

d) Open the evacuation cock on the filling device slightly.

Let out the nitrogen (N) slowly until the gauge has

reached the target pressure.

e) Close the evacuation cock, take out the filling device,

tighten the gas filling plug and put back the lead mould

plug (if provided).

2. Increase pressure:

For tank filling only use nitrogen (N), no

oxygen (danger of explosion).

f) Connect the filling device onto the nitrogen bottle.

g) Take out the plastic cap.

- Take out the lead mould plug (if available) in the gas

filling plug (44) with the help of a sharp tool.

- Loosen the gas filling plug (44) only slightly.

- Screw on the filling and verification device.

h) Screw the verification device onto the nitrogen bottle.

i) Open the evacuation cock on the filling device slightly

and fill with nitrogen until the gauge reads the target

pressure.

k) Close evacuation cock, take out the filling device, tighten

the gas filling plug and put back in the lead mould plug

(if available).

Note

All gas accumulators show a slight pressure drop after a

certain period of time, according to "HYDAC" factory

specifications.

The gas loss amounts to approx. 2-3 % pa.

It is recommended to check and if necessary correct tank

pressure after 4-5 years.

MAINTENANCE

Basic setting of the ploughing component

Checks must be made in the following order after replacing worn out parts:

1. Stand the plough on even ground.

2. The gap (A) between plough and share cutting edge must be the same for all ploughing components.

3. Check the gap (B1) on the last ploughing component.

B1 = 0 - 5 mm for ploughing components* of the type W, UWS

10 - 20 mm for ploughing components* of the type UW, UWS, WSS

4. Set the same measurement for gap (B) as for B1.

* The type of plough body is shown clearly on the manufacturer’s plate.

Setting the ploughing component tilt

If the plough is not penetrating the ground correctly, an

improvement can be obtained by turning the eccentric bush.
