2. TECHNICAL DATA
3. GENERAL DESCRIPTION
The Power Box Rake is designed to carry out various tasks, including cultivating, raking,
levelling and earth-moving.
A heavy rotor with special carbide teeth is mounted on it. The rotor is hydraulically propelled
and can rotate in both directions. The rotor can be adjusted to the left and to the right in order
to move rocks, etcetera to the side. The abridged operation of the various functions is:
-Cultivating
The rotor can be lowered into the ground and grind the soil. The side plates are used
to keep the soil in the machine, to sweep the waste in front of the machine and to
keep the treated soil clean.
-Raking
Rocks / stones can be raked to the side(s) by adjusting the working depth in such a
manner that the rotor teeth just touch the ground and by adjusting the rotor to the
side(s).
-Levelling
You can level the ground accurately by adjusting the machine in such a manner that
the rotor teeth touch the high points in the field and move the soil to lower lying parts
of the field.

6. Start the tractor and drive off.
7. SAFETY WHEN USING THE POWER BOX RAKE
Before using the Power Box Rake, you should check the following:
1. Are there slopes? The maximum slope is 20 degrees for this machine. Always go from top to
bottom.
2. Are there hard objects in the ground? If so, use the Power Box Rake at adjusted speed.
3. Is there danger of flying objects (e.g., golf balls) that distract the attention of the driver? If so, the
Power Box Rake CANNOT be used.
4. Is there danger of sinking/sliding away? If so, postpone the treatment.
5. If the soil is frozen or very wet, postpone the activities until conditions improve.
6. Do NOT make sharp curves when the Power Box Rake touches the ground.
8. PROCEDURES
The start procedure is VERY important. Follow the described procedure precisely, because otherwise
the Power Box Rake can get damaged. The rotor can rotate in both directions. It is important to stop
the rotor before reversing the rotating direction. Changing the rotating direction too fast can damage
the hydraulic engine.
!! Redexim does not accept responsibility for damage to the hydraulic engine due to
operating errors by the operator !!

8.1. Starting to cultivate
The Power Box Rake can cultivate soil effectively at a depth between 50-100mm.
1. Raise the guide plate by loosen the nuts (1) and tighten the nuts. Make sure that there is
minimum 50mm distance between the rotor and the rubber plate (X) (Figure 3).
Figure 3
2. Make sure that the rotor frame is perpendicular to the tractor (Figure 4).
3. Lower the machine until the rotor is just above the ground, but does not touch it.
4. Set the engine of the shovel to approx. 1,200 rpm and engage the rotor. Pay attention: the
rotating direction must be opposite to the driving direction!
5. Increase the number of revolutions of the engine to approx. 2,000 rpm. This ensures that the
number of revolutions of the rotor increases.
Figure 3

Redexim
13
6. Start moving the shovel and lower the Power Box Rake until it touches the ground. It is
essential to drive slowly (1-2 km/h). Soil and rocks will now accumulate in front of the rotor,
they will be forced over the rotor, and this will leave a level condition of the field behind the
machine.
7. To adjust the working depth, the wheels (2) can be put higher or lower by dividing the rings
differently (3). Set the number of rings in the same way for both the left and right wheel.
(Figure 3).
Stopping occurs as follows:
1. Reduce the speed and the number of revolutions of the engine.
2. Lift the machine off the ground.
3. Switch OFF the rotor.
8.2. Starting to cultivate
The Power Box Rake can move soil, rocks, rubble, etc. This can be done by using the machine to pull
the material forward.
1. Lower the guide plate by loosen the nuts (1) and thigten the nuts. Make sure that there is a
minimum distance (X) between the rotor and the rubber plate; make sure that the rubber plate
just does not touch the teeth (Figure 3).
2. Make sure that the rotor frame is perpendicular to the tractor (Figure 4).
3. Both side plates (2) must be placed in such a manner that they point straight forward. This can
be done by placing the locking pins (1) in the rear hole (Figure 5).
Figure 5
4. Make sure that the working depth is set so that the teeth of the rotor do not cut the soil. To
adjust the working depth, the wheels (2) can be put higher or lower by dividing the rings (3)
diffently. Set the number of ringsin the same way for both the left and right wheel (Figure 3).
5. Lower the machine until the rotor is just above the ground, but does not touch it.
6. Set the engine of the shovel to approx. 1,200 rpm and engage the rotor. Pay attention: the
rotating direction must be opposite to the driving direction!
7. Increase the number of revolutions of the engine to approx. 2,000 rpm. This ensures that the
number of revolutions of the rotor increases.

Redexim
14
8. Start moving the shovel and lower the Power Box Rake until it sinks into the ground. Rubble
and rocks will now accumulate at the front of the rotor and shifted forwards. The fine material
will be forces over the rotor and this will leave a level condition of the field behind the machine.
The high parts of the surface are levelled and the lower parts are filled with soil. The machine
pushes large pieces of rubble and rocks forward and by raising the machine slowly, these
pieces can be laid aside at the end of the surface that is treated.
Stopping occurs as follows:
1. Reduce the speed
2. Lift the machine off the ground.
3. Switch OFF the PTO.
8.3. Starting to cultivate
The Power Box Rake can move soil, rocks, rubble, etc. to the side of the surface that is treated. When
the surface to be treated is entirely raked, it is ready for further treatment e.g., sowing grass.
1. Lower the guide plate by loosen the nuts (1) and tighten the nuts. Make sure that there is a
minimum distance (X) between the rotor and the rubber plate; make sure that the rubber plate
just does not touch the teeth (Figure 3).
Figure 6
2. Rotate the rotor by operating the hydraulic cylinder (3) (Figure 6) so that the material is moved
to side.
When the material has to be moved to the right side, turn the rotor to the left and place side
plate (1) maximum turned to the outside (Figure 6). Fix the side plate by using the lock pin and
secure with the R-clip.

Redexim
15
When the material has to be moved to the left side, turn the rotor to the right and place side
plate (2) maximum turned to the outside (Figure 6). Fix the side plate by using the lock pin and
secure with the R-clip.
3. Make sure that the working depth is set so that the teeth of the rotor cut the soil at approx. 10-
15cm. To adjust the working depth, the wheels (2) can be put higher or lower by dividing the
ring differently. (3) (Figure 3).
4. Lower the machine until the rotor is just above the ground, but does not touch it.
5. Set the engine of the shovel to approx. 1,200 rpm and engage the rotor. Pay attention: the
rotating direction must be opposite to the driving direction!
6. Increase the number of revolutions of the engine to approx. 2,000 rpm. This ensures that the
number of revolutions of the rotor increases.
7. Check the treated surface. The surface should be level and without rubble or rocks.
8. To obtain a finer finish, it might be necessary to drive slower or to raise the Power Box Rake.
9. Pay attention that the machine always drives in the same direction. Do NOT drive back and
forth along the same track; otherwise the rocks and rubble are not moved to the side of the
surface.
You can do this by driving in ever-increasing circles.
Or, by starting in the centre of the field and driving back and forth along the already treated
strip, making sure that the machine can move the material outwards.
9. TRANSPORT
The user is responsible for transporting the Power Box Rake in back of the tractor on public roads.
Verify the national legislation regarding the regulations. On open fields while the machine is raised, the
maximum permitted speed is 20 km/h (12.4 mph) due to the weight of the POWER BOX RAKE. A
higher speed can be dangerous for the driver and/or the public and can even damage the machine.
!! When the machine is raised off the ground, the front axle of the tractor has to support
minimum 20% of the tractor’s weight !!
