How to read the instruction manual
It is possible that the order in which the topics are listed does not appear as logical.
Please refer to the table of contents, where the titles for the relevant topics can be
found.
The main points in the instruction manual are divided into 4 key sections:
•Safety
•Operation (Settings, driving and servicing)
•Maintenance
•Repairs
The following symbols are used in the instruction manual for:
Points that are especially important for the functionality as well as the lifetime of the
machine.
Points that are relevant to safety.
Delivery
The front harrow is supplied completely assembled via platform truck.
If the front harrow needs to be lifted, it is recommended that this is done with
straps, so that it hangs balanced.
Check the harrow for any damages upon receipt of the machinery. Check the hydraulic
hoses for damage (H models). The machine must be placed on a fixed and level surface.

Limitations in use
The following describes what the machine may/must not be used for:
•The machine may only be used for tilling land containing
stubble and grass in agricultural areas that have been
cultivated. Those areas to be tilled must have been subject to
normal agricultural maintenance, i.e. without significant bumps
or holes.
•It may also be used for the maintenance of grassy areas,
paddocks, golf courses, sports facilities, parks and other places
where an airing and breakdown of soil and plant residue is
desired.
•The machine may only be used after first being attached to an
agricultural tractor, by way of connection to the front-mounted
3-point hitch.
•The machine may work at a maximum speed of 8-14 km/h. The
speed shall however always be adjusted to the nature of the
area.
Any other use of the machine, which does not fulfil the
aforementioned conditions, will be considered as unauthorised
use, and will result is a revocation of the manufacturer's
warranty.

Use
The front harrow is a front-mounted universal tool that can be used for a
wide range of work in the fields. Together with a MaxiDisc disc harrow or a
drum behind the tractor for example, it is possible to perform “double” the
tilling of stubble and grass with a front harrow, and establish a false seed
bed if desired, in one round. This can be of great benefit in a meadow, for
example, or where there are large amounts of plant residue, or for the
distribution of straw prior to tilling the soil itself. It is mounted with two rows
of 16 mm harrow tines as standard.

Connecting and
disconnecting
Connecting
The lifting arm is mounted first using
the hitch pins (A), after which the top
mount pin (B) is mounted.
Remember to raise the support legs
and secure them with stud and cotter
pin (C). See figure 2.
Figure 2
Remember to secure the studs with the linchpin and ensure that the lock
mechanism in the lifting arm's hook has been turned on.
Angle of the lifting arm
Efforts must be made to ensure that the tractor's lifting arm, when the machine is
lowered into its working position, is at a horizontal angle at minimum or pointing
slightly higher. This enables the machine to roll easily over any obstacle it
encounter, as the tractor pushes the machine upwards on a tilt while also
maintaining control. See figures 3 & 4.
Figure 3
Figure 4
Hydraulics
A double-acting check valves is required at the front on the tractor for folding in and
out (H models).
Check that the hydraulic hoses have not been crushed.

Transport lock (500H & 600H models only)
Once the hydraulic hoses have been connected to the tractor's female quick
couplers and there is pressure in the system, the transport lock can be
disconnected from transport position (A) and moved to position (B).
Figure 5
Figure 6
N.B. When driving on public roads, the transport lock must be placed in transport
position!
Disconnecting
The front harrow shall be lowered onto a fixed surface before disconnecting and its
sides shall be folded down (H model). Disconnect hydraulic hoses (500H & 600H
models) and lifting arm/top mount. Lower the support legs and secure with studs
and cotter pins, see figure 2.
Remember to remove the pressure from the connecting hoses (H models) to the
hydraulic system before disconnecting the hoses. This can be done when the front
harrow is folded down completely, see figure 7.

Settings
The front harrow is factory set at delivery, but fine tuning will always be necessary
before taking into use. Many different adjustment options make your front harrow
more versatile and offers the potential to gain optimal use of the machine.
As a standard setting, the front harrow shall be set to run in horizontal position
while operating in the fields. This standard setting is important in order to leave
the field with an even service as well as to achieve a consistent working depth.
Figure 8
Figure 9
Adjustment of working depth
The working depth of the harrow is set via the perforated panels (A) on the support
wheel as well as with the tractor's lifting arm. The frame must be horizontal in
working position on both sides, see figures 9 & 10. The front lift must be in the float
position.

Adjusting the harrow tines
The tines angle on the harrow can be changed, as shown in figure 12, by using 4
spindles (A). In order to achieve the same angle on all 4 bulls, the measuring tool
should be used, figure 13 (B), which is placed as shown in figure 14 (C). There are
small notches on the measuring tool that can be adjusted according to the spindle
length.

Driving and operating
Correct operation is important in order to get optimal use from your front harrow.
This applies not only to working in the field but also in terms of safety. Which is why
it is crucial that you have read the instruction manual and are familiar with the
safety precautions that cover the machine.
Working depth
The front harrow can be set to a very light tilling, down to working depth of just a few
cm.
Driving speed
It is recommended that the machine be driven at 8-14 km/h, but driving should
always be done according to conditions.
If the speed is increased, wear will also increase, especially under dry conditions.
There is also a risk of damaging the harrow tines by driving at excessively high
speeds under adverse conditions.
Power
The power requirement is very dependent on the type of soil and terrain as well as
the speed.

the same angle.
•Adjust the spindle.
•The front harrow tilts
backwards/
forwards.
•The depth of the lifting arm
needs regulating.
•Regulate the support wheel.
Hard to control
•The front harrow is not level
on the undercarriage –see
figures 3 & 4.
•Adjust the top mount pin.
•The top mount is too long.
•Adjust the top mount to a
shorter length.
•Too great a working depth.
•Raise the machine.

Maintenance
Good maintenance ensures a long life of the harrow and therefore optimal use of the
machine. Grease fittings have therefore been mounted in places where wear is
greatest.
All screw connections must be tightened after the first day of work. Cotter pins and
bolts should be checked to avoid breakdowns. It should also be checked that the
hydraulic system is air-tight.
Lubrication
Figure 14
All lubrication points should be greased at least once a
year.
