Side 8
Hydraulics
•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.

cause severe injury. In the event of injury, seek medical help immediately.
Assembly
•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 or fully extended 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 fitting the correct lighting and number plate required in ac-
cordance with applicable legislation.

MaxiCut
Side 9
•Check with local traffic authorities whether transport on public roads is al-
lowed given the machine's dimensions.
•When transporting, ensure permitted total weight for tractor is not ex-
ceeded and that loading on tractor front axle is not less than 20% of trac-
tor net weight. If this is the case, use weights on tractor front
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.
•MaxiCut may only be used, maintained or repaired by personnel familiar
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
MaxiCut is a newly-developed heavy blade roller, designed for use on crops
with long, thick stems. By cutting the remaining organic materials, decompo-
sition is accelerated.
Fig. 1
MaxiCut is a blade roller, on which
the sections are independent of each
other. Heavy-duty bearings are stan-
dard.
MaxiCut 600 at work
MaxiCut is used after harvesting on crops such as maize, sunflower or rape,
when the total weight of the machine and ground conditions are optimum.
When the rollers are filled with water and the ground is as dry as possible, the
machine is at its most effective.
The machine has to be operated at relatively high speeds of over 15 km per
hour, preferably 18-25 km per hour at which the rollers will perform best on
stubble and plant residue. For an extra thorough result, another run can be
made over the field.
The rollers are designed to be filled with water if required. The machine
comes from the factory without water to simplify transport.
L
The steel tubes may only be filled with water or liquid with a density less
than 1.15 g / cm³. This avoids overloading the machine's hydraulics and
welded frames.

Connecting and disconnecting
Connecting Fig.2
MaxiCut is attached to the tractor's
lifting arms and secured using
balls and split pins (A). The sup-
port leg (B) is raised and secured
by a pin (C). MaxiCut 200/300
coupled so that the drum section,
always preferred to in paragraph
(D).
Remember to secure drawbar with balls and split pins.
Hydraulics MaxiCut requires a double-acting hydraulic outlet, in which one line is used
for lowering the side sections and other for towing the frame to transport the
roller from field to field.

Setting up
MaxiCut is very simple to work with. The design makes it very simple to set
up, although the main frame must be horizontal.
Always check frame angle before use to ensure optimum use of the machine.
Adjusting drawbar
To ensure uniform cutting, the drums must be horizontal on the drawbar. The
side frames can swing in relation to the lie of the field.
Fig. 3
MaxiCut 600 at work. The main
frame is horizontal whilst the side
frames are free to swing.
Incorrect drawbar height can cause uneven compression of the soil, as the
roller will not apply equal pressure for all sections. If the drawbar is low at
the back, the tractor lift arm is too high. If the drawbar is low at the front,
raise the tractor lift arm.

Operation
Correct operation is vital for optimum use.
This applies to working in the field and for safety. Always ensure you are ful-
ly familiar with all safety aspects of the machine.
Extending and retracting
Extending and retracting the machine must always be performed with tractor
parked.
Extending
Fig. 4
1Remove transport chain, extend
side sections to horizontal using
the extend cylinder (hose
marked: red).
Fig. 5

(marked: Red) to fully extend
side sections.
3Raise wheel frame (marked: yel-
low)
L
Before commencing rolling, drawbar must be horizontal. When driving with
MaxiCut 200/300 lift must always be in a floating position when the machine
is in working position.
By turning with the machine on the headland, the machine has to be
lifted up on the wheel frame to make sure, that the frames will not be
overloaded. Slight curve speed can be made with the machine in the
ground.

MaxiCut
Side 17
Retract
Lower wheel frame and raise roller clear of ground.
Retract side sections, fit transport chain.
Operating speedAn operating speed of 18-25 km/h is recommended, but always operate ac-
cording to conditions.
Increased speed will increase wear, particularly in dry conditions. There will
also be a risk of the roller throwing up soil and stones.
Power
Power requirement will depend on soil type, terrain and speed.
