Safety
This symbol appears in the instruction manual each time there is a safety
warning concerning your safety, the safety of others or functionality of the
machine. All safety instructions must be observed and made available to all
users of the machine.
General
Ensure you are familiar with all aspects of the machine before use
There are safety stickers on the machine containing important instructions
for the safety of yourself and others, and correct use of the machine.
Do not carry passengers during operation or transport.
Ensure there are no personnel within the machine's working radius before
operating. Operate machine only from inside the tractor.
Before leaving the tractor or making adjustments, performing maintenance
or repairs on the machine, fully lower to ground, or maintain in transport
position, apply tractor handbrake, switch engine off and remove ignition
key to secure the machine against accidental operation.
Remember to secure the lift arm with a split pin.
Never leave driver's seat whilst machine is moving.
Always adapt speed to conditions.
Do not use machine unless all safety devices are in place. Defective safety
devices must be replaced immediately.

Hydraulics
Ensure there are no personnel within the machine's working radius when
activating the hydraulic system to avoid danger of crushing.
Lower machine fully for any repair work on the hydraulic system. Relieve
hydraulic pressure, switch engine off and remove ignition key.
Clean hydraulic connections thoroughly before reconnecting. When con-
necting hydraulic hoses to tractor hydraulics, ensure they are not under
pressure.
Bleed the hydraulic system thoroughly after any repairs.
Check hydraulic hoses regularly for defects such as cracks, splits, crimps,
wear or breaks. Defective hoses must be replaced immediately.
Avoid spilling oil on the ground. If oil is spilt, collect and deliver to a de-
struction point.
Clean hands thoroughly after contact with oil and grease. Change oil-
stained clothing immediately. Hydraulic oil can be harmful to the skin.
Hydraulic oil released under high pressure can penetrate the skin and
cause severe injury. In the event of injury, seek medical help immediately.
Mounting
Danger of crushing! Ensure no personnel are between implement and
tractor, or between the parts to be connected.
Maintenance and repair
Ensure machine is adequately supported for all repair and maintenance
work. Ensure tractor and machine are properly braked, engine stopped and
ignition key removed.
Tighten all screw connections after a few hours use. Check all screw con-
nections regularly and tighten as required. Check all split pins and bolts to
avoid mechanical failure.
Dispose of oil, grease and filters in accordance with local environmental
protection rules.

Road transport
All safety and warning precautions mandatory by law must be fitted and
tested before transporting the machine on public roads. The driver is re-
sponsible for correct lighting and warning signs in accordance with traffic
regulations.
Check with local traffic authorities whether transport on public roads is al-
lowed given the machine's dimensions.
When transporting machine, ensure tractor total weight and axle pressure
are not exceeded.
Correct use
Correct use of the machine includes observing the manufacturer's operat-
ing, maintenance and repair instructions, and that original spare parts are
always used.
The machine may only be used, maintained or repaired by personnel fa-
miliar with it and who are aware of the risks that can be involved.
The manufacturer cannot be held liable for injury or damage arising from
modifications made to the machine performed without prior permission
from the manufacturer. Neither can the manufacturer be held liable for in-
jury or damage arising from incorrect use. Such liability rests solely with
the user.
Do not add extra weight to the machine

Uses
The Ratoon subsoil loosener can be used for grubbing uncultivated arable
land and in plantations etc to a maximum depth of 70 cm. The Ratoon is a
rear-mounted implement, and the depth it works at is governed by the tractor's
3 point linkage, its wheels and tubular packer roller. It is ideal for use on
wheel tracks and pre-ploughing where arable soil is often unnecessarily com-
pacted.

Connecting and disconnecting
Connecting
Fig. 1
Connect lift arms first using lift
pins (A). Connect top bar to point
(B).
Remember to secure attachment using split pins and check lift arm hook lock
mechanism is engaged.
Remember to move support leg to relevant position
Hydraulics A single-acting hydraulic outlet is required on the tractor to adjust the hydrau-
lic stone guard system.

Disconnection Lower machine to ground before disconnecting. Disconnect hydraulic hoses
and lift arms. Disconnect light if relevant. Remember to set support leg in rel-
evant position.
Remember to depressurise hoses before disconnecting them.Ball cock
must be closed before disconnection. Failure to do so will cause pressure
loss. Machine will drop to ground.

Setting up
The machine is supplied with factory settings, but fine adjustment will always
be required before use. Numerous adjustment options make it more flexible
and ensure maximum use.

Basic setting will ensure the machine will run horizontally. This is achieved
using the top bar. This basic setting is important to achieve an even field
surface and uniform working depth.
Adjusting depthSet depth using the drilled plates (A) on wheels and using tractor lift arms.
Both sections of frame must be horizontal. If the machine is fitted with a
packer roller at the back, use this for setting depth rather than the wheels.

Adjusting pressure of hydraulic stone guard
Hydraulic system pressure must be adjusted according to soil type. Very hard
soil will require much higher pressure than sandy soils.
In ordinary conditions, a pressure from 45 bar to max. 80 bar is recommend-
ed. Remember to close ball cock on feeder hose when pressure has been ad-
justed. The manometer has a factory setting of 50 bar.
Pressure must not exceed 80 bar to allow tine flexibility in con-
tact with foreign objects.
Fig. 5
Check all the accumulators on the machine at least once a year for leaks and
to ensure that the precharge pressure is set correctly. Contact an author-
ized Dal-Bo dealer for more information.

Operation
Correct operation is vital for optimum use. This applies to working in the field
and for safety. Always ensure you are fully familiar with all safety aspects of
the machine.
Do not turn or reverse while the machine's tines are in the ground.
Working depth The machine can be set for a very light effect. Depth can be controlled very
precisely by the tractor's hydraulic lift or by a combination of wheels or pack-
er roller. As such, it can be set for very light effect at a depth of only 25 cm
approx. Working at this depth will only lightly break up the soil. Never set
depth at more than 70 cm. Exceeding this setting can damage the machine.
Fig. 6
Ensure machine works parallel to
ground when in operation.
Operating speedAn operating speed of 0-6 km/h is recommended, but always operate accord-
ing to conditions.
Increased speed will increase wear, particularly in dry conditions. The har-
rowing tines can also be damaged if operating at excessive speeds in unfa-
vourable conditions.
Power
Power requirement will depend on soil type, terrain and speed.

Hydraulics
Check all hydraulic hoses for wear or cracks. Check all hoses for crimping.
Replace defective hydraulic hoses immediately. Broken hoses can cause
injury or damage to the implement.

Lubricate exposed rams with oil or pressure-resistant grease to avoid rust
forming when storing for long periods. Remember to remove before use.

Replacement andrepairs

Safety is vital for all repair work on the machine. Always observe the fol-
lowing points, plus those under Safety First in the instruction manual.
All maintenance and repair work can only be performed when the machine is
lowered to the ground or locked in transport position, tractor is braked, en-
gine stopped and ignition key removed to prevent accidental start.
Particular attention must be paid to safety when repairing hydraulics. Before
commencing work, depressurise hydraulic system and support part being
worked on.
Always ensure hydraulic system is bled after repairs and before use to pre-
vent mechanical breakdown and injury to person.
Replacing stone guard cylinder
Support main frame securely. Depressurise hydraulic system.

Ensure no personnel are within working radius of the implement when hy-
draulic system is activated.
