Vehicle / Tractor Preparation
We recommend vehicles are fitted with cabs
using ‘safety glass’ windows and protective
guarding when used with our machines.
Fit Operator Guard (See drawing) using
the hooks provided. Shape the mesh to cover
all vulnerable areas. The driver must be
looking through mesh and/or polycarbonate
glazing when viewing the working tool in any
working position - unless the vehicle/ cab
manufacturer can demonstrate that the penetration resistance is equivalent to, or
higher than, that provided by mesh/polycarbonate glazing. If the tractor has a roll bar
only, a frame must be made to carry both mesh and polycarbonate glazing. The
operator should also use personal protective equipment to reduce the risk of serious
injury such as; eye protection (mesh visor to EN1731 or safety glasses to EN166),
hearing protection to EN352, safety helmet to EN297, gloves and high visibility
clothing.
Vehicle Ballast
It is imperative when attaching ‘third-party’ equipment to a vehicle that the
maximum possible stability of the machine and vehicle combination is achieved –this
can be accomplished by the utilisation of ‘ballast’ in order to counter-balance the
additional equipment added.
Front weights
May be required for rear mounted machines to place 15% of total outfit
weight on the front axle for stable transport on the road and to reduce ‘crabbing’ due to
the drag of the cutting unit when working on the ground.
Rear weights
May be required to maintain a reasonable amount of rear axle load on the
opposite wheel from the arms when in work; for normal off-ground work i.e. hedge
cutting this should be 20% of rear axle weight or more for adequate control, and for
ground work i.e. verge mowing with experienced operators, this can be reduced to
10%.
All factors must be addressed in order to match the type and nature of the equipment
added to the circumstances under which it will be used –in the instance of Power Arm
hedge cutters it must be remembered that the machines centre of gravity during work
will be constantly moving and will differ from that during transport mode, therefore
balance becomes critical.

Factors that affect stability
Centre of gravity of the veichle/machine combination.
Geometric conditions, e.g. position of the cutting head and ballast.
Weight, track width and wheelbase of the tractor.
Acceleration, braking, turning and the relative position of the cutting head
during these operations.
Ground conditions, e.g. slope, grip, load capability of the soil/surface.
Rigidity of implement mounting.
Suggestions to increase stability
Increasing rear wheel track; a vehicle with a wider wheel track is more
stable.
Ballasting the wheel; it is preferable to use external weights but liquid can
be added to around 75% of the tyre volume –water with anti-freeze or the
heavier Calcium Chloride alternative can be used.
Addition of weights –care should be taken in selecting the location of the
weights to ensure they are added to a position that offers the greatest
advantage.
Front axle locking (check with tractor manufacturer).
NOTE: The advice above is offered as a guide for stability only and is not a guide to vehicle
strength. It is recommended that you consult your vehicle manufacturer or local dealer to obtain
specific advice on this subject, additionally advice should be sought from a tyre specialist with
regard to tyre pressures and ratings suitable for the type and nature of the machine you intend
to fit.

Introduction
The GreenTec Crusher is a very robust high capacity Rotary Crusher that is easy to operate
and maintain. To ensure trouble-free operation this manual should be carefully studied
Attaching to an Arm system
Fit the machine to the vehicle in the standard way,
ensuring the correct match of linkage (category 2
linkage pins). Check that the top link is in good order
and threads are well lubricated. Use stabilizers to
take any free movement out of the lower link arms.
Before fitting the machine to the vehicle linkage you
should ensure there is sufficient front weight to
ensure the front wheels are always in contact with
the ground. This is most important for safe transport
and stability when turning on slopes.
Before fitting the PTO for the first time it may be necessary to adjust the length. There should
be maximum engagement of the sliding tubes without bottoming at the shortest operation
position. To check, first connect the mower to the vehicle.
Pull the PTO shaft apart and connect to the vehicle PTO output shaft and the gearbox input
shaft. Hold the half shafts next to each other in the shortest working position. If necessary
shorten the inner and outer guard tubes equally.
Shorten the inner and outer sliding profiles by the same length as the guard tubes. File all
sharp edges and remove burrs. Grease sliding profiles
Important
On delivery of your machine check that the Dealer has completed the P.D.I. form, ensure
the warranty registration form is completed and returned
Safety first
Do not start the machine until you fully understand the operation and safety precaution
requirements. Always ensure the operator is proficient with the operation of this type of
machine

GreenTec

Setting up and adjusting
Height
Cutting height adjustment is achieved by your operating system, when you work with the
machine.
Machine Protection
A flotation system can be used in the connection
between the GT 135-155 and the armsystem, also a
skid is mounted on each side of the head
Important
If the machine has been laid up for any length of time, there is a risk of risk of moving parts is
stuck. They must be lubricated and loosened before using the machine.
Start the motor up at idle speed and allow it to "warm" up. If imbalance is observed, stop the
machine immediately. Check that there are no tangled cords, plastic, grass or other debris
around the rotor shaft or tools..
If in any doubt, consult your local GreenTec dealer or GreenTec Service Department for further
advice

Operation
Engage the PTO only when the engine is at low revs to prevent shock damage to the machine.
Slowly increase the engine revs to achieve the standard PTO speed.
If at any time serious vibration occurs, stop the engine immediately and check that no
tools are missing - following all safety precautions.
The cause must be found and rectified immediately or other components may be affected
When in work, lower the machine to the ground carrying its weight on the skids and as option
on floatingsystem, allowing the machine to follow the contours of the ground and ensuring
there is sufficient slack in the mounting bracket. Select a sensible forward speed bearing in
mind the density of growth, the terrain, and the available horsepower, taking extra care when
turning, particularly on slopes.
When turning, it is not necessary to lift the machine off the ground but instead allow sufficient
room to turn in a large radius. The machine only needs to be raised when turning in a tight
corner or reversing over dense undergrowth, or when operating on the front linkage
Quality of finish is determined by the forward speed, i.e. a slow speed will produce a high
quality of cut, whereas faster forward speeds are used when high output is first priority
Transportation
Please observe Public Highway Regulations concerning the towing of implements, and
securely attach a registration and lighting board.
Take care to slow when travelling over rough ground and avoid bouncing the machine on
linkage, causing unnecessary strain

Service & Maintenance
Safety First
Never leave the vehicle seat without first disengaging the PTO and stopping the engine
Ensure all rotating parts have stopped turning
Never attempt any repairs, maintenance, service or any other checks with the machine
carried on the vehicle hydraulics.
Always fully lower to the ground, or securely prop the machine on substantial servicing
stands.
Always refit all guards and retaining chains after servicing/maintenance is completed
Important
Never carry out any servicing or maintenance work without first disengaging the PTO and
stopping the tractor engine
It is imperative that the following checks are carried out in order not to invalidate your warranty.
These are carried out before the first operation, after the first hour, then after 4 hours. The
checks are
Hydr. Motor bolts
Blade bolts are fully tightened, in particular the castle headed nut on the blade rotor
Retaining bolts on the drive shaft
It is your responsibility to maintain the machine to ensure a long
reliable working life

Regularly
Check there is no wrapping of string, plastic, grass or other debris between rotor boss
and blades.
Inspect motor seals for leaks.
Regularly check the rotor and fully tighten the Castlenut.
Regularly check the rubber protection.
It is most important that all Hydraulic motor and blade bolts are regularly checked to be
very tight. When the machine is new there will be a ‘bedding in’ period where very
frequent checking is important.
Blades or chains
The blades can be re-sharpened by grinding the cutting edges and care must be taken that the
blades are of the same weight and length after grinding. Do not over heat when grinding, as
this will affect the hardness of the blades
All the blades are free swinging and swivel on hardened steel bushes, which are easily
replaced. When replacing blades, it is important that blades are replaced in sets, in order to
retain balance of the rotor. Bushes must be replaced when new blades are to be fitted.
If the blades are showing any signs of severe wear, damage or cracking, they must be
replaced immediately. Never attempt to weld the blades, this will make them very brittle thus
extremely dangerous. Do not take risks with the cutting blades - if in doubt, replace.
Skids
When operating on abrasive soils, particularly in stubbles and similar conditions with thin
ground cover, excessive skid wear may be expected.
If working in wet and muddy conditions, ensure that debris is not allowed to build up on, or
under, the deck.
Caution!
When carrying out maintenance work on or near the blades, be careful of free-
swinging blades over-centering and falling. It is recommended that protective
headgear, gloves and goggles are worn

GreenTec

Storage
Before storing away, thoroughly wash the machine, removing all traces of grass and dirt.
Great care must be taken when washing with high-pressure hoses, do not hold the water jet
close to the paintwork
Do not use steam cleaners and be sure to remove all detergents to avoid any discolouring or
damage to paint. Grease all grease points until fresh grease shows. Store PTO shaft in a dry
place
Remember, the GreenTec machine is designed to withstand the most rigorous
conditions as bush and up to 60 mm thickness, and with a little care and
attention will give many years of trouble free service. In order not to invalidate
the warranty and to avoid problems use only genuine parts
