2.1 General safety instructions
Familiarize yourself carefully with this manual and make sure that you have understood the in-
structions regarding the mulcher and related information.
Everyone using the Mulcher must follow the given instructions. If the mulcher is given temporari-
ly to other user than the owner of the machine, or if it is rented, make sure that the user has
read this manual and understood safe and proper use of the machine.
2.2 Instructions for safe use
WARNING! Minimum safety distance is 10 metres.
WARNING! The mulcher must be lowered onto the ground, the parking brake
must be applied, and the power take-off must be disengaged when leaving
the base machine!
WARNING! Rotating machine parts - Never get close to rotating parts, shafts,
drums, or blades, and never attempt to service them while the machine is
running.
•When coupling or uncoupling the mulcher, make sure that the parking brake is en-
gaged. Eliminate the risk of getting crushed between the mulcher and the base
machine.
•Before operating the machine make sure that the mulcher and its hydraulic fittings
are coupled properly.
•Before moving the mulcher the operator of the mulcher / base machine must
check the operation of the control systems and movements.
•During use ensure that there are no others closer than the minimum safe distance,
and that the visibility is adequate.
•Operate the machine calmly and adjust the drive speed according to operating con-
ditions.
•Make sure that all guards are in place and fitted securely.

•Ensure before using the mulcher that the hydraulics of the base machine are com-
patible for the attachment. Check this from the manufacturer of the base machine
or the authorized dealer of the base machine. Suokone Oy is not responsible of
compatibility or usability of the hydraulics of the base machine to operate this at-
tachment.
•Always ensure that there is a pressure relief valve at the hydraulic line connecting
the hydraulic motor, and that the pressure relief valve is adjusted so that the max-
imum allowed pressure of the hydraulic motor is not exceeded. Ensure that the re-
turn lines from the hydraulic motor are connected directly to the hydraulic reser-
voir.
•Note that when switching off the hydraulic circuit the kinetic energy of the rotor
must be directed somewhere. If lines that are not equipped with a pressure relief
valve are closed, the kinetic energy of the rotor will cause pressure spikes to either
pressure or return line, which can damage the hydraulic system.
2.3 Safety instructions for maintenance and service
WARNING! The base machine must always be switched off before any
maintenance work!
WARNING! When doing maintenance or service work, always ensure that
there is no risk of dropping of parts and risk of crushing!
•Never do maintenance or service while the mulcher is lifted supported only by
hydraulics, and ensure that the parking brake of the base machine is engaged.
•Relieve the pressure from the hydraulic parts before starting service.

2.4 Description and location of decals on the mulcher
•The identification plate includes information about the type, weight, serial number, and
year of manufacture. The identification plate is located on top of the hydraulic motor.
•The lubrication points are marked with a red round label.

3.1 Designed purpose of use
Mulchers are intended for conditioning of soil in different operating areas. Mulcher are well suit-
ed for landscaping, farms, green area maintenance, and municipalities.
In landscaping and farming the mulcher can be used to till soil before planting and sowing. In
addition, the mulcher can be used to crush small tree stumps and other vegetation.
Use in municipalities and green area maintenance: Clearing of shrubs and tree stumps at vari-
ous areas. The mulcher are well suited for crushing ice and clearing of hard snow ridges on
roads.

3.2 Operating principle
The mulcher is hydraulically operated. The hydraulic motor in fitted directly on the rotor shaft.
Power from the base machine is transferred hydraulically. There are blades on the rotating rotor
to crush the material that is handled.
Determining the rotating direction
•UP-Rotation
The blades go upwards at the rear of the attachment.
•DOWN-Rotation
The blades go downwards at the rear of the attachment.
CAUTION! In case you want to change the direction of rotation please contact your
dealer or the manufacturer.
3.3 Noise level
The sound pressure level at 10 meters from the machine is 75 dB(A). Measurement uncertainty
is 1,5 dB(A).
The sound power level is 102 dB when measured across spherical surface according to stand-
ard ISO 3744:2010. Measurement uncertainty is 1,5 dB.

4 Coupling and uncoupling of the mulcher
4.1 Coupling and uncoupling of the mulcher
When coupling or uncoupling the mulcher form the base machine always make sure to eliminate
the risk of getting crushed. Ensure that the mulcher is on solid, level ground and supported be-
fore disconnecting it from the base machine. Prevent the mulcher from tipping over. When cou-
pling the mulcher make sure that the locking pins and the hydraulic fitting sare connected se-
curely. Always before use check the hydraulic functions. Mulcher can be stored so that it is on
its skids.

5 Using the mulcher
5.1 Equipment
1. Counterblade
The counterblade minimises the space between the frame and the rotor. The material being
mulched is forced to go through the rotor and the counterblade. The counterblade improves the
mulching performance.
2. Pivoted support skids (optional equipment)
The skids are pivoted and help to control the mulching depth. The skids slide on mulched soil
and make accurate control of mulching depth possible, preventing the rotor from going too
deep, when i.e. crushing built up ice from parking areas and other paved surfaces. This option
is recommended when handling ice or hard packed snow.
3. Bottom plate
The bottom plate is a wear part that is fastened with bolts to protect the frame of the attach-
ments. When the bottom plate it can be replaced.

5.2 Working and adjustments
•Adjust the operating speed and depth so that the mulcher runs smoothly.
•Set the engine rpm of the base machine while the mulcher is lifted off the ground.
•Switch on the hydraulics while the mulcher is lifted.
•Keep the mulcher supported with the boom while using it.
•If the rotor stalls repeatedly, use lower drive speed or reduce the mulching depth.
•Even though the mulcher is equipped with wear resistant blades, try to avoid big
rocks, which can damage the rotor or other parts. The mulcher is not intended to crush
stones even though it can withstand occasional contact with those.
•It is possible to press down the mulcher against its support skids. The required mulch-
ing depth is adjusted with tilting adjustment. Using the support skids reduces the ten-
dency of bouncing. The support skids will make work on ice and packed snow much
easier.
CAUTION! The hydraulic system allow the rotor to rotate to both directions, but
the mulcher must be used only when the rotor rotates to the direction the blades
point. The reverse direction can be used to clear possible blockages. In case of a
blockage lift the machine up and use it to reverse direction to remove the material
blocking the rotor. Working with the reverse running direction can cause the blade
holders to wear down quickly.

6 Lifting / storage
Lifting
Warning! Lift the mulcher only from the dedicated points, always using ap-
proved type lifting equipment, chains, and ropes!
Storage
Store the mulcher on a covered area, on a platform, after cleaning and after adding grease to
lubricating points.

7 Maintenance / Service
Additional service tasks for a new mulcher:
-Tighten bolts and nuts after the first two hours of use.
-Check the hydraulic hoses / motor for possible oil leaks, and if necessary, tighten fit-
tings.
7.1 Lubrication
The bearing 1 after every 8 hours of use, 10 to 15 presses of a grease gun.

7.2 Wear parts
•Check and replacement of wear parts
Warning! Always use safety goggles when replacing blades. During welding and other
service use appropriate personal protective equipment.
STD- Rotor
1. Remove locking nut
2. Punch the broken blade loose
3. Set the new blade and locking nut to their place

CR 1400

•Check and replacement of blade holders
Remove the damaged blade holder (A) and place a new holder (B) onto the place of the old
one. Check the correct welding spots on the rotor from the other non-damaged blade holders.
Connect the electrode clamp directly to the rotor for welding.
Notice the inclination of the blade holders: 5 degrees.

1.Counterblade
Worn counterblade can be replaced with a new one, or the worn edge of the blade can fill weld-
ed using hard weld Esab Weartrode 55HD, or similar according to ISO EN 14700, E Z Fe 6.
2. Support skids
When the skids wear they can be either replaced or repaired by welding.
3. Bottom plate
When worn out this must be replaced with a new one.
