4 Operating manual for the Vario harrow

4.1 Mounting on the tractor

Under difficult operating conditions, additional wheel weights can be useful. Please also refer to the

operating manual from the tractor manufacturer.

The tractor should be equipped with sufficient ballast weight at the front to ensure the steering and

braking capacity. At least 20% of the empty vehicle weight is required on the front axle.

The lifting links must be adjusted to the same height on the left and on the right. The implement must be

mounted on the 3-point linkage of the tractor. In doing so, the lower top link hole must be used.

Mount the top link so that it slants down towards the tractor during operation. (Observe the specifications

from the tractor manufacturer.)

4.2 Safe parking

1. The parking surface must be suitable for parking

the implement. The ground must be firm and

level, so that the stands do not sink in and the

harrow does not roll away.

2. To ensure safe parking of the implement, lower

the stands at the rear of the harrow.

3. Make sure that the tines do not touch the ground

in the process to prevent damage to the tines.

4. The stands must be secured with a spring cotter

on the pin to prevent accidental loosening.

5. The securing chains must be hooked onto the

side frame.

6. Then the pressure in the hydraulic hoses to the

tractor must be relieved.

4.3 Folding the Vario harrow

1. Fold the implement only when it is raised from the ground.

2. Ensure that no one is standing in the danger area!

3. Couple the hydraulic line plugs. (ensure that they are always

kept clean!)

4. Afterwards, fill the cylinder with oil. The cylinders are filled as

soon as the load on the securing chains is relieved.

5. Unhook the securing chains.

6. When folding into transport position, the implement must also

be lifted from the ground and the harrow tines must be folded

up.

7. The feeler wheels on the side frame must be completely

raised before the harrow can be folded.

8. Hook on the securing chains again after the harrow has been

folded.

9. The tines may be pre-tensioned only when the Vario harrow is

unfolded.

During the folding procedure, first the outer side frame is folded by

180° onto the inner frame, which is then folded up by 90°.

The hydraulic connections for folding and tine pre-tensioning are marked with cable ties. If two cable ties

are attached to the hose, it means that it is the flow line (+). In contrast, if only one cable tie is attached

to the hose, it is the return line (-).

Figure 4

ba_vs_v1.0_en.docx Page 7

PLEASE NOTE!

When uncoupling the hydraulic hoses for the tine pre-tensioning under pressure, first

close the stop tap, and only then unplug the hydraulic hoses. By doing so, the tines

remain in the desired position, even when the harrow is parked.

4.4 Transport supports

Before initial operation of the Vario harrow, all of the transport supports must be removed:

• Loosen the bolts and pull off the supports.

TIP!

If the harrow is not used for an extended period of time, the transport supports can be

installed on the feeler wheels to relieve the tyres during longer downtimes.

If they are not used, the transport supports must be disposed of properly.

5 Working position and setting the working depth

The harrow intensity is set with the

pre-tensioning of the spring pack. The

pre-setting is made hydraulically and

comfortably from the tractor seat. On

the scale (see Figure 8), the driver

can read the level that is currently

set. Here, the springs are not pre-

tensioned at positions -3 to 0. Pre-

tensioning begins at 0, and the full

pre-tension is reached at position 6.

At position -3, the tines are folded up,

which means that the tines are in

transport position.

The working speed has a significant

effect on the intensity of harrowing.

The normal speed range is between 4

and 12 km/h, depending on the crop

sensitivity.

The feeler wheels can be moved on the frame to the desired track

width. The harrowing height can be adjusted with the pattern of holes

in the feeler wheels. The higher the feeler wheels are moved up in the

frame, the smaller the distance between the frame and the ground and

the more slanted the position of the tine ends relative to the ground.

Scales are attached to the feeler wheels. When all of the feeler wheels

are set to the same number, all of the feeler wheels are at the same height.

PLEASE NOTE!

If the feeler wheels are moved down again, it does not result in more pressure on the

tines, but rather only the working depth is increased.

PLEASE NOTE!

Ideally, there should be a right angle

(90°) between the wearing end of the

tines and the soil (see Figure 10 -

centre). Because of the pre-tensioning,

the right angle is only reached while

driving.

All of the tine rows should penetrate the soil to the

same depth (working depth), i.e. the frame must run

parallel to the ground.

To achieve this, the extension of the top link must also be adjusted. The parallelism of the frame to the

ground can be read on the spirit level on the centre frame.

CAUTION!

When the harrow is lowered, do not allow it to push or roll back with the tractor;

otherwise, the tines and bearing points can be damaged.

Figure 10: A 90°-angle is ideal

ba_vs_v1.0_en.docx Page 9

CAUTION!

Driving in curves is not permitted. If there is no other option, these curves must be

driven in a very large radius.

5.1 Hydraulic tine adjustment

The tines are adjusted with multiple hydraulic cylinders connected in parallel. This allows the tine

position to be changed while driving.

All of the hydraulic cylinders (Figure 11) are connected by an oil circuit. Adjustments are made using a

double-acting control unit and the flow divider on the centre frame (Figure 12).

5.2 Additional adjustment options for ground adaptation

The slot in the cylinder working point further improves the

ground adaptation of the Vario harrow. If the laterally bolted,

folding locking plates installed, the upward ground

adaptation is fully available, but the downward ground

adaptation is limited. This has the advantage that the

harrow sags less, which is helpful when turning. If the plates

are removed, the ground adaptation is available in both

directions.

Figure 13: Folding locking plate

Page 10 ba_vs_v1.0_en.docx

6 Maintenance and care

PLEASE NOTE!

When the implement is lifted off of the ground, the two side wings of the frame should be

pointing slightly down. If this is not the case or if the wings are pointing down too much,

the stop bolts on the joint must be adjusted.

To maintain the implement in good condition even after a long service life, the following instructions must

be observed:

• In the supplement "For your safety…" you will find some basic safety regulations for maintenance

work.

• Original parts and accessories are designed especially for the machines or implements.

• Please note that parts and accessories not supplied by us have also not been tested and approved

by us.

• The installation or use of such products can therefore possibly negatively change or impede the

constructional properties of your implement. The manufacturer rules out any liability for damages

resulting from the use of non-original parts and accessories.

• The manufacturer is not liable for any unauthorised modifications and the use of components and

mounted parts on the implement.

• All bolted connections should be re-tightened at the latest after 3 operating hours and again after

20 hours, and then checked regularly. Loose bolts can cause significant consequential damage,

which is not covered by the warranty.

• The grease points on the joints and bearings must be lubricated regularly (approx. every 10

operating hours with universal grease).

• After the first 10 operating hours and subsequently every 50 operating hours, the hydraulic units

and tube lines must be checked for leaks and the bolted connections must be tightened if

necessary.

• Check the hydraulic hoses for wear before every operation.

• Caution! Liquids escaping under high pressure can penetrate the skin. For this reason, a physician

must be consulted immediately in case of accident!

• After cleaning, lubricate all of the grease points and distribute the grease evenly in the bearing

points (e.g. perform a short test run).

• Do not use a high pressure cleaner to clean bearing and hydraulic parts.

• The paint can be damaged by cleaning with excessive pressure.

• During the winter, the implement should be protected against rust with an environmentally-friendly

product.

• Park the implement protected from weather conditions.

• Hydraulically as well as mechanically folded implement must only be parked in a folded state.

• Put down the implement in a way that the tines are not needlessly strained.

• Occasionally check the tyre inflation pressure (4 bar).

10.1 Transport on public roads (in general)

• Check that none of the safety splints or similar were lost during operation.

• Comply with the regulations of your country's legislation.

• Only relieve the hydraulic hoses shortly before uncoupling the tractor by putting the tractor control

unit into float position.

• The axle load and the total weight of the towing vehicle may not be exceeded.

• The mounted implement must be identified with warning signs or stickers with red and white

slanted lines (according to DIN, ÖNORM or respective STANDARDS) according to the regulations

of the specific country.

• Any part posing a traffic hazard or dangerous parts (tines) must be covered and additionally

identified

• with warning signs or stickers. Warning signs or stickers should be visible at a height of max. 150

cm above the road when driving.

• Lighting equipment on the towing vehicle may not be hidden by the implement, otherwise they

must be installed on the mounted implement.

• The steering capacity of the tractor must not be impeded or reduced by the mounted implement!

• Semi-mounted implements may only be towed on public roads with an operating permit.

• Hydraulic implements must be folded in transport position.

• Ensure that the stop tap (if equipped) is closed or the securing chains are hooked.

• Also ensure than none of the safety splints were lost during operation.

• Comply with the regulations of your country's legislation.

• Only relieve the hydraulic hose at home by putting the tractor control unit into float position. The

bracket for the warning signs (additional equipment) is mounted on the centre frame (see point 14

10.2 Calculation of the weight ratios

for axle loads on the tractor and ballast weights

Implements mounted on the 3-point hitch change the total weight and the axle loads of the tractor. These

values may not exceed the permissible measures. The load-bearing capacity of the tyres must also be

observed.

The front axle of the tractor must be loaded with at least 20 % of the net weight of the tractor.

The necessary ballast weight as well as the actual axle loads can be determined using the following

formulas:
