TRACTOR REQUIREMENTS

Tractor

To operate this machine the following tractor requirements

are necessary:

Tractor power: at least 92 KW / 125 HP (5 plough

body)

at most 265 KW / 360 HP (9 plough

body)

Hitching category: Lower link Cat. III

Connections: See table "Necessary hydraulics

and power connections"

Tyres

Wheels

- The air pressure in the rear tyres of the tractor when

ploughing depends on the type, you can take as reference

value 0.8 bar.

- Under heavy working conditions additional wheel weights

can be advantageous.

See the operating instructions of the tractor manufacturer.

Distance between the wheels

The distance between the wheels (A1) should be of 1.2

m - 1.5 m.

A1 = 1.2 ... 1.5 m

A2 = max. 3 m

External dimensions

The external dimensions (A2) of the rear wheels may

not exceed 3 m. When the 3 m are exceeded, the

manoeuvrability is relatively limited.

Ballast weights

The front of the tractor is to have sufficient ballast to

guarantee braking and steering capabilities.

At least 20% of the tractor’s tare weight

on the front axle!

Lifting gear (three-point linkage)

- The tractor’s lifting unit (three-point linkage) must be

designed for the load that occurs. (See technical data)

- The lifting struts are to be set to the same length with

the corresponding adjustment device.

(See the tractor manufacturer’s operating manual)

- Select the rear position if the lifting rods can be adjusted

in various positions on the lower link. This relieves the

pressure on the tractor’s hydraulic system.

- The limit chains resp.stabilisers of the lower links are to

be set so as no side movement of the hitched devices

be possible. (Safety measure for transportation)

- The upper link is to be removed according to the data

provided by the tractor manufacturer.

Set furrow width "First body"

Plough starting position:

Optional pin: Changing setting prior to use

Optional hydraulic cylinder: Setting can also be changed

during use.

Mode of operation:

The plough position relative to the tractor is adapted with

the setting furrow width "First body". The plough is moved

with a pin or a hydraulic cylinder depending on the version.

The setting is to be selected so that the furrow width of

the first body (S1) is the same as the other plough bodies.

Design

with pin:

The furrow width "First body" (S1) is adjusted steplessly

by turning the pin (Sp).

- Furrow width (S1) too narrow -> turn pin (Sp) shorter

- Furrow width (S1) too wide -> turn pin (Sp) longer

Setting furrow width

Plough starting position:

Variant Standard:

Change setting before use

Variant Servo Plus:

The setting can be changed also during operation. (See

Chapter "Servo Plus" for details)

Mode of operation:

The plough working width is determined by the furrow

widths set for the individual bodies.

Variant Standard: 5 defined furrow widths can be set

mechanically.

Variant Servo Plus: The furrow width can be set steplessly

using the hydraulics.

Variant: Standard

Setting the furrow width per body:

- Loosen front hex head bolt (vS).

- Remove rear hex head bolt (hS).

- Swivel the fastening bracket until the required furrow

width is reached and the hex head bolt (hs) fits into one

when operating

the hydraulic

control.

Setting the depth

Plough starting position:

The plough must be rotated in working position

Mode of operation:

The working depth is set on the chassis and via the lifting

height of the tractor lower link.

The adjustment of the chassis height is made with the help

of the hydraulic cylinder (Zy).

The setting of the working depth resp. is changed via the

number of the depth stops (AS) swivelled in.

074-09-54

Design:

- Lift the chassis

- Remove cover of the depth stops (lynch pin) and fold

- Swivel the depth stop in or out (less depth stops = more

working depth)

- Fold up and secure the cover of the depth stops

- Lower the chassis (until the cylinder (Zy) lies on the

depth stops.)

- Adjust the lifting height of the tractor lower link to the

required working depth.

One depth stop corresponds to a change

in the working depth of approx. 2 cm

Adjusting the plough tilt

Plough starting position:

Prior to use.

Mode of operation:

The tractor drives in the furrow and is thus at a slope. The

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

during ploughing. The setting of the tilt is performed via

adjustment screws at the swivel unit.

Design:

- Adjust the tilt per side with the adjustment screws (1).

(Example: If the plough is swivelled to the right, the left

stop can be set)

- Check that the new setting allows the plough bodies

to stand approximately vertical (90°) to the ground per

side.

074-09-60

When ploughing on slopes, it is

recommended that the tilt is set somewhat

more than 90°.

When ploughing on hard ground, it is

recommended that the tilt is set somewhat

less than 90°.

SERVO NOVA

Fully automatic „Nonstop“ overload safety

The fully automatic overload safety is recommended for

soils which are difficult to plough e.g. soil with stones or

other foreign bodies.

Every ploughing component is hydromechanically

safeguarded against damage on the SERVO-NOVA

plough.

When driving over an obstacle the ploughing body swings

out to either side and then swings automatically back into

the working position. There is no need to stop the tractor.

The plough body swings back into work position

automatically.

Along with the fully automatic „Nonstop“ overload safety,

all component carriers have a shear bolt as additional

protection.

Setting range

The overload safety release force can be adapted to the

various soil types.

Normal setting
