If a reversing manoeuvre is required at the end of the row being tilled, the tractor p.t.o.

must be switched off and the rotary harrow allowed to come to a complete standstill before
it is lifted out of the ground for the manoeuvre (risk of clods of earth being hurled off by the
tines).

The cardan shaft must always be disengaged and the ignition key removed before starting

any maintenance and repair work on the rotary harrow!

However, the following points should be observed nevertheless:

Maintenance or repair work must never be performed underneath the power harrow

without appropriate supports. Precautions must always be taken to prevent the machine
from dropping inadvertently, for instance by using hoisting gear.

The power harrow should be stored in a dry place, on firm, level ground. It should be

secured with chocks or similar objects to prevent inadvertent tilting.

The power harrow type FIELDKING POWER HARROW is designed and built to require

as little maintenance and care as possible.

All nuts, bolts and screws must be examined after the first five hours of operation and then

always before using the machine in order to ensure that they are secure. They must be
retightened if necessary.

The cardan shaft must be lubricated with sufficient sulphur-free grease every eight hours

of operation so that it can always be extended and retracted without difficulty. The bearing
points on the cutter unit, the spindle for setting the working depth and the roller mount
must be lubricated every 30 hours of operation.

The oil must be checked every 20 hours of operation.

The machine must be thoroughly cleaned before prolonged storage. Those parts which

are in contact with the ground during operation should be sprayed with corrosion inhibitor.

Particular attention must be paid to the condition of the tines in order to ensure maximum

occupational safety and high-quality results. Before starting work, the tine must therefore
be examined to ensure they are correctly secured and wear down evenly. Bent tines must
be replaced immediately.

Dust clouds may form when operating the power harrow at higher speeds on dry ground.

Light respiratory protection should therefore be worn when using a tractor without closed
driver’s cab.

4. Maintenance, care and transport:

The power harrow should always be placed on firm, level ground.

Vibrations in the power harrow are usually due to imbalances in the tine unit and may

damage the machine. Switch off the power harrow and the tractor if the vibrations
increase significantly during operation or if the machine’s running noise changes
suddenly. The cause must be located and remedied before resuming work.

Gear oil must be changed after approx. 200 hours of operation. A container must be

placed under the machine to collect the escaping oil and prevent contamination of the
ground. Waste oil must be disposed of in accordance with the regulations.

First switch off the tractor and remove the ignition key.

Remove the fastening bolt and nut with a suitable wrench.

The power harrow should only be repaired by a specialist repair shop or the FIELDKING

customer service centre.

If the tines have to be reground, care must be taken to ensure that each pair of tines in the

tine unit is reground. This prevents the tine unit concerned becoming imbalanced.

All faults capable of impairing safety must immediately be remedied by specialist

personnel.

The screw connections between tines and tine flange / guard plate must be checked

regularly. Always fit new lock nuts and new washers whenever the screw connections
have been removed. The condition and degree of wear on the tines and tine pick-up must
be checked regularly.

Remember to support it so that it cannot tip over inadvertently.

Changing and regrinding tines:

When cleaning the machine with a high-pressure cleaner, care must be taken not to direct

the high-pressure jet against bearings and seals, as this can result in malfunctions and
premature failure of the machine.

Removal of the tines:

Installation of the tines:

When transporting the machine, care must be taken to ensure that there is no one and

nothing in the immediate vicinity when sluing outwards with the tractor.

5. Safety instructions:

Fit the tines in the correct order (see Fig. 2).

The POWER HARROW may only be used when all safety mechanisms are in place and

fully functional.
