Application
The FARMERDISC is an entirely new generation of very compact and simple mounted
disc harrows.
The FARMERDISC is particularly suitable for working in the topsoil where the majori-
ty of plant transformation takes place. With only one drive the FARMERDISC is able
to provide a complete cutting of the field and a homogeneous mixing of crop resi-
dues and micro-organisms in the soil. To keep the soil moist and thereby optimise
the microclimate for the organisms, the working of the soil is completed by a pack-
ing.

Adjustments and Settings
The FARMERDISC is preset in the factory, but it will always be necessary to make
some fine adjustments before use.
Numerous adjustment possibilities make your FARMERDISC more versatile and allow
you to obtain optimum performance from the implement.
Depth
The operating depth is controlled by the rear T-ring roller or the Tube-packer.
Fig. 3
The working depth of the discs is ad-
justed with pins in the hole plate. The
upper pin (A) determines the working
depth. The lower pin (B) is a supporting
pin, which carries the rear roller when
the FARMERDISC is lifted.
When changing the working depth it may be necessary to readjust the top link as
the frame should always be level during operation.
Deeper tillage
Deeper tillage can be obtained by lifting the implement from the ground. In that way
the pin (A) can be removed from the hole plate and be placed in a higher hole. Lower
the FARMERDISC and similarly move up the lower pin (B), so that the support is as
close to the lift arm as possible.
.
When the FARMERDISC has been adjusted to deeper tillage it may be necessary to
drive the discs in the soil (or support the rear roller) in order to add pressure to the
rear roller. After this the lower pin (B ) can easily be fitted in to the hole closest to
the lift arm.

Operating and Driving Instructions
Proper operation is essential for optimum performance of your FARMERDISC. Proper
operation concerns both the carrying out of tillage operations in the field, as well, as
the following of safety precautions. Make sure that you have a thorough under-
standing of all safety precautions.
Position the FARMERDISC so it is supported by the rear roller. Lower the lift of the
tractor completely when driving in the field, so the lift is floating and is moving in
accordance with the terrain.
Travel Speed
The recommended driving speed is 8-12 km/h. However, one should always drive
according to conditions.
Please note that wear is heavily increased when speed is increased, especially un-
der dry traffic conditions. Points and wearing parts (e.g. plates and rear roller) may
be lost or damaged, when driving too fast under unfavourable conditions.
Effect
The need for effect is depending on soil type, terrain and speed.

Maintenance
Proper maintenance ensures a long life for the FARMERDISC, and optimum perfor-
mance from the implement. To facilitate maintenance, grease fittings have been
mounted on those locations, where wear on the equipment is the greatest.

Tighten all nuts, bolts, hydraulic fittings or any other fastened as-
semblies after the first workday. Inspect all pins and bolts for wear
or damage, and make sure, that all are securely in place, to avoid
any possible damage or breakdown of the machine. Check for leaks
in the hydraulic system.
Before servicing the machine, always lower the implement, engage
the tractor breaks, stop the engine and remove the ignition key to
avoid unintentional operation and personal injury.
