1. SAFETY INSTRUCTIONS
1.1 General safety instructions
The user of the coulter is responsible for his or her own safety and that of bystanders in the area around this
machine. It is therefore essential that the user has sufficient knowledge about the use of the machine and how to
couple it to the tractor.
The figures and descriptions in this manual must be provided to both users and maintenance staff and the general
instructions must be observed with regard to the use and maintenance of the machine. If there is any doubt or lack
of clarity, the dealer can always be consulted.
This machine may only be used for the purpose for which it has been designed and tested. Moreover, the machine
may only be used with a suitable tractor and be powered by a suitable power take-off drive on the tractor. Any other
use is strictly prohibited.
The machine has been built in accordance with the applicable safety regulations, which is why the manufacturer
cannot be held liable for damage that arises from:
• The use of the machine if one or more of the covers/guards is missing.
• Incorrect use of the machine.
• The use of the machine by untrained people or by people who have not been give authorized access.
• Incorrect coupling of the machine to the tractor.
• Defective or insufficient maintenance.
• Unauthorized changes or activities performed on the machine.
• Use of non-original spare parts or parts not specific to the machine.
• Non-compliance with all or a part of the instructions in this manual.
• Extraordinary weather conditions.
Workplace
When working with the machine, the operator must sit on the seat of the tractor: any other location is not allowed
ever.
Bystanders may not come too close to the machine when it is being used. It is possible for objects to be ejected from
the machine. The operator of the machine must always remain approximately 100 m (328 feet) away from
bystanders.
Only leave the driver’s seat when:
• The power take-off shaft has been switched off.
• The engine has been switched off.
• Rotating parts have come to a standstill.
Noise
The noise level is such that the level to which users are exposed on a daily basis is less than 70 dBA. This
measurement was made using a sound level meter at a distance of approximately 1.6 m (5.25 feet) from the
machine and at a height of 2 m (6.56 feet). The machine has been adjusted to an unloaded work area and has a
rotational speed of 540 rpm of the power take-off shaft on ground on which grass grows.

Vibrations
During normal operation, the machine transmits minimum vibrations to the tractor. These vibrations are lower than
0.5 m/s2 to 2.5 m/s2 for the operator.
Clothing
• Do not wear jewelry or loose clothing (such as ties, scarves or open clothing) that could touch moving parts of
the machine.
• Always use safety shoes, safety goggles and gloves.
• Wear a jacket with high-visibility sections when it is dark (e.g. a high-visibility jacket).
• Never use the machine under the influence of alcohol, illegal drugs or other stimulants that may slow down
your reflexes.
1.2 Safety instructions before use
The Boxer Coulter SB can be used for different activities:
• Preparation before sowing.
• Burying mowed material.
• Loosening hard earth.
The coulter is not suitable for working on stony ground. Stony ground may damage the protective covers and guards
of the machine. Such use may make the warranty null and void.
WARNING
If there are stones in the soil, they must be carefully removed. The rotor of the machine may become stuck and
therefore be damaged.

2. INSTALLING THE POWER TAKE-OFF SHAFT
If the power take-off shaft is too long, it must be shortened as follows:
• Position the machine at a minimum distance from the tractor and switch the tractor off completely.
• Check the position and, if required, adjust the bolts.
• Separate the two halves of the shaft.
• Keep the two halves next to each other so that they are parallel.
• Use a marker to indicate the location where the two halves must be shortened 25 mm from the beginning of
each half as shown below in Figure 1.
Figure 1
• When sawing part 1 (Figure 2), use the length as shown above.
Figure 2
• When cutting part 3, use part 2 to cut off the correct length.
• Saw and smooth the two ends of the power take-off shaft and clean them of any dirt and sawing residue.
• Lubricate the two ends and join the two parts of the power take-off shaft once again.
• Install the power take-off shaft and check that the length is correct.
• Protection systems can be installed: shear bolt coupling/friction clutch.

3. SETTING THE WORKING DEPTH
Skids
CAUTION
The following procedures must be carried out once the machine and tractor have been switched off completely and
have been uncoupled from each other.
The working depth can be set by adjusting the skids with regard to height.
Figure 3
• Use bolts "2" to adjust the skids with regard to height.
• Tighten bolts "2" firmly after setting the working depth
(skid fastened low, working depth deep/skid fastened high, working depth shallow).
Roller
Use lever "1" or "2" to determine the working depth of the roller.
Figure 4
CAUTION
Make sure that the skids are positioned equally after setting the working depth. Also check whether the length of
the blades matches the working depth.

4. IMPORTANT PARTS
1. Three-point hitch: for coupling the machine to the tractor.
2. Power take-off shaft protection: prevents that the user comes into contact with the rotating part of the
transmission that is coupled to the power take-off shaft.
3. Gearbox: reduces the rotational speed of the tractor's power take-off shaft.
4. Transmission chain: the movement of the gearbox is transferred to the rotor through the transmission chain.
5. Frame: this is the backbone of the machine.
6. Roller: adjusts the depth of the work. As an alternative, the coulter can be equipped with rear wheels. They
work in the same way.
7. Rotor shaft: the tractor drives the rotor shaft on which the coulter blades are screwed on.
8. Coulter blades: the blades are screwed onto the rotor's flanges.
9. Rear cover: the cover can be moved (Fig. 5).
10. Skids: you can use these to adjust the working depth of the blades. They also act as important side shields.
Figure 5

9. WORKING METHOD
• The operator may not become distracted when he/she operates the machine.
• Pay additional attention when working on slopes. By preference, have the tractor and machine drive
horizontally to prevent tipping over.
• Also follow the instructions of the manufacturer of the tractor, in particular, with regard to the maximum
gradient on which you can work.
• When working on a slope, we recommend restricting the working speed while gradually changing speed and
the direction of the vehicle during maneuvers.
• Never work on wet grass, a slippery surface or when the tires do not grip. If this is unavoidable, drive at a low
speed to guarantee safety.
• Pay attention to possible obstacles, stones or other objects that may hit the machine.
• Always check local legislation and regulations with regard to using public roads.
• Add reflecting triangles on the rear and check the position of lights and emergency lights when you use public
roads.
• Check whether all oil tanks are at the right level and lubricate all required points.
Starting from the stationary position
• Allow the blades to drop up to just above the ground.
• Position the power take-off shaft.
• Lower the lifting height of the tractor.
CAUTION
Lower the lifting height slowly so that the blades gradually cut into the soil. If lowering too fast, the coulter blades
may become damaged.
• Press the gas pedal about halfway and, next, set the power take-off shaft at 540 rpm.
• The tractor's speed must be adjusted to the soil type and the degree to which it must be plowed. (The optimum
work speed is between 1.5 and 2.5 km/hour (0.93 to 1.55 miles/hour).)
• To find the optimum speed, first select the lowest gear to gradually increase up to the ideal driving speed is
reached.
• The slower the tractor moves, the more the soil will be plowed.
• Stop after a few meters (feet) to examine the result of the plowing. If the result is not what is required, again
adjust the working depth or the driving speed.
• Every time the machine must be adjusted, you must switch off the tractor completely. Wait until the rotor has
stopped rotating.
• Lift the machine from the ground during maneuvers, bends, reversing and when uncoupling the power take-
off shaft. Never lift the machine more than 250 mm (10") out of the soil. The power take-off shaft of the
transmission can break and this may possibly lead to damage or injury.

Page 17/24
December 2020COULTER | User manual
• The machine can plow on a slope with a gradient of 20° at
most. If the gradient is higher, the machine may start to vibrate
considerably or the power take-off shaft may break (see
Fig. 11).
• When the operator operates the machine, the plowed soil
must always be kept on the right side of the operator.
