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 Armsystem
Fit the machine to the tractor 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 tractor 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 tractor.
Pull the PTO shaft apart and connect to the tractor 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.

Setting up and adjustment
Height
Cutting height adjustment is achieved by your operating system, when you work whit
the machine.
Machine Protection
There is a flotation system in the
connection between the GT 135-155 and
the armsystem, and also a skid on each
site of the head
Important
If the machine has been laid up for any length of time, there is a risk of
Finally, re-tighten the tension spring bolts to their original length, taking great care not
to over-tighten.
If in any doubt, consult GreenTec Service Department or your local GreenTec dealer
for further advice.

GT 135-155

Operation
Engage the PTO only when the tractor 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 blades 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,
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 tractor 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 tractor hydraulics.
Always fully lower to the ground, or securely prop the machine on substantial
servicing stands.
Always replace 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.
Warning
Never carry out any servicing or maintenance work without first disengaging the PTO and
stopping the tractor engine.

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 nut.
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. To provide extra
protection and to prolong life of the skids, special hard facing rods are available.
If working in wet and muddy conditions, ensure that debris is not allowed to build up
on the deck.
Caution!
When carrying out maintenance work on or near the blades be careful of free-swinging
blades over-centring and falling. It is recommended that protective headgear, gloves and
goggles are worn.

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 and drive belts 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
