ATTACHING TO THE TRACTOR

Preparations on the tractor

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.

- Road transport not in “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.

Mounting axle (965 mm / 825 mm)

• Use the correct mounting axle

- see also spare parts list.

• Carry out adaption to the tractor´s lifting gear

- both helical plates can be fitted in 4 different positions

(P1, P2, P3, P4)

Upper link pins

Position upper link pins (6) as per diagram

- secure with linch pin (K).

- 8 -

1400_GB-ANBAU_983

ATTACHING TO THE TRACTOR GB

Attaching to the tractor

- 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.

Important advice:

Supportstand in the working position

1. Lock the bolt (1) into the hole of the stand plate.

2. Secure the supportstand with linch pin (K).

Insert pin only in the first hole.

• Do not use holes in pos. 2 - 9

- otherwise support stand will be damaged when

turning plough

Lighting and Warning equipment

When travelling in fog, half-light or at night, protruding

parts are to be clearly indicated. Advice on the application

of warning signs, reflective

film or paint and lighting

units can be found in the

instructions for ancillary

equipment in supplement C.

PôTTINGER can supply

lighting units and warning signs upon request.

Always observe the statutory regulations.

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.

- Switch tractor’s

hydraulics to control

position.

- Disconnect hydraulic hoses from tractor.

- Swing support stand down and secure with pins.

- Detach upper and lower links from implement.

OPERATION

Caution when driving into the field with

SERVO 35 and 45

Be advised!

Danger of material damage when driving

into the field - when the plough is still in

transport position (horizontal position)

and is therefore raised (distance A). The

spindle can be damaged in case of strong

vibrations.

Therefore transport the plough by

transport wheel or first turn plough into

working position.

Rotating the plough

Beware!

During plough rotation, nobody is allowed

within the swing range.

Operate the rotating unit only from the

tractor seat.

For the rotating process, the plough must

be lifted fully.

The rotating unit is equipped with double-acting cylinder

and integrated automatic reversing gear.

The automatic reversing gear enables the whole turning

procedure to be carried out through only one single

switch position on the control unit (ST). (Necessary oil

quantity: 40 - 50 l/min)

TD 65/92/48

ST

Rotating process

The rotating process is performed in the same way with

the help of the single-acting or double-acting control

device.

For the single-acting control device you need a return

pipe on the tractor.

- Switch the control device (ST) to Lift (h).

(for the version with single-acting cylinder or memory

cylinder first you swivel in the frame), after turning you

swivel it back out. see chapter Variants.

The plough body is rotated with 180°.

- Switch the control device (ST) to Neutral (0).

After about 5 seconds, you can perform a new rotating

process.

Setting the plough inclination (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 the plough 5 - 10 cm.

- Operate the control device (ST) briefly.

The plough frame rotates away from the stop spindle

(11).

- Set the inclination with the help of the spindle (11).

- Rotate the plough frame back to stop position.

- Continue ploughing and check whether the new setting

brings the plough bodies to approximately vertical

position (90°) to the ground.

OPERATION GB

Setting the plough on a tractor with

"Servomatic"

The setting technology "SERVOMATIC" adjusts plough

and tractor optimally to one another.

The following setting controls should be carried out in order.

• Never reach into the crushing

danger zone as long as parts are still

moving.

• Do not stand in the swinging

range of the implement.

1. Setting furrow width

- See chapter "PLOUGH PRESETTING"

2. Cutting width setting of the first plough body

(backfurrow)

The cutting width (S2) of the first plough body is set by

rotating the spindle (VF).

Cutting width (S1) too narrow

- Rotate spindle (VF) further.

Cutting width too wide

- Rotate spindle (VF) less.

Cutting width (S2) correct

- The spindle is set correctly.

See chapter "PLOUGH PRESETTING"

Hydraulic cutting width adjusting (SERVO PLUS)

Therefore an additional double-action control unit is

necessary on the tractor.

3. Set the drawing point (Z)

Setting correct

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

the tractor’s rear axle. No side pull occurring on the tractor.

The plough is operating smoothly.

- Spindle (ZP) set correctly.

See chapter "PLOUGH PRESETTING"

Setting wrong

The drawing line does not run through the mid-point of the

tractor’s rear axle.

a.) When ploughing the tractor is pulled into the ploughed

area. This can only be compensated by steering in the

opposite direction.

- Rotate the spindle (ZP) further.

b.) When ploughing the tractor is pulled into the unploughed

area.

- Rotate the spindle (ZP) less.

OPERATION GB

Ploughing with adjusting hydraulics

Observe the following so that the adjusting hydraulics

operate correctly.

TD65/92/27

P2

- Pin the upper link (1) so that during operation the

connecting point on the plough (P1) is a little higher

than the connecting point (P2) on the tractor.

Pinning the upper link

LL, RL = Securing position for securing lower link.

RL = Securing position for securing upper link.

See chapter „ATTACHING TO THE TRACTOR“ also.

- During operation, the plough frame shall be placed

longitudinally, approximately in parallel to the field

surface.

- First, the working width is adjusted with the help of the

lifting device via the control valve (ST).

Changing ground resistance during ploughing,

depending on the model of the adjusting hydraulics,

is transmitted to the control valve via the upper link

(1) or the two lower links. The relevant impulse is then

converted causing the lifting gear to lift or lower.

One example: Upper link adjustment

The plough goes deeper into the ground.

Thus the pressure on the control valve becomes higher

through the upper link.

As a result, the control valve is switched on Lift until

the set working depth is reached again.

Note:

Also observe the operating instructions of the tractor

manufacturer.

Hydraulic cutting width adjustment

(SERVO PLUS)

The adjusting device is operated with the help of a

hydraulic cylinder. Therefore an additional double-action

control unit is necessary on the tractor.

You can also perform a stepless adjustment of the cutting

width during ploughing. The drawing line position is not

influenced by this (see "Setting the drawing point (Z)").

Advantages:

- Exact ploughing on the edges.

- Ploughing around obstacles (masts, trees etc.).

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 À 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)

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.

See chapter "OVERLOAD SAFETY“ for a description.

Setting range

• The triggering force of the overload safety can be

adjusted function of the various ground types.

Normal setting

- The pressure on the hydraulic cylinders (40) must be

approx. 10 bar higher than the nitrogen pressure in the

gas tank (43).

Nitrogen pressure in the gas tank (43) (factory

setting)

80 bar

Setting range for the pressure in the hydraulic

cylinders (40)

90 to 160 bar

If you see during practical operation that the overload

safety triggers too often, you can increase the pressure(*

in the hydraulic cylinders with the accompanying top-up

device (42) (see table).

drops.

- Operate the control valve on tractor until the gauge

indicates the target pressure. Then close the shut-off

valve (position A).

Beware!

The stopcock must always be closed during

ploughing (position A).

- Depressurise the top-up pipe by means of the control

valve.

SERVO NOVA GB

Gas tank (43):

The pressure in the gas tank can also be changed.

Reducing or increasing the gas pressure in the tank

depends on the various types of ground.

• In case of very light ground, you can reduce the gas

pressure to a certain extent.

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

Advice for general maintenance

In order to keep the implement in good condition even after

a long service life, please observe the following points:

- Retighten all screws after the first hours of operation.

During the operating season

- Check all screws occasionally and retighten if necessary.

- Grease the four greasing points on both of the swing

bolts weekly.

- Grease all lubrication points weekly.

- Grease the lubrication points at the wheel case at least

twice per season.

At the same time oil joints and adjusting spindles also.

Wearing parts

- Replace worn out expendable parts in time to prevent

any stress-bearing parts from becoming damaged.

Tyre pressure

- Pay attention to the correct tyre pressure!

Check tyre pressure regularly!

• Danger of bursting when pumping up or

when tyre pressure is too great!

Cleaning of machine parts

Be advised!

Do not use a high pressure cleaner to clean bearings

and hydraulic parts.

- Danger of rust!

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 ploughing component 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.

• The blade point in the area „S“ is set either higher or

lower depending upon the position of the eccentric bush

(A or B).

• Retighten screws after resetting.

On some models a catch plate is fitted instead of an

eccentric bush.
