Hazards associated with operating Grass Cutting Machinery
Shear Hazard
Shear hazards are created when the edges of two objects move toward or next to each other closely enough to cut
relatively soft material. This can include the parts of the machine under hydraulic control when operating from transport
to mowing position. Note, the wing units are designed to oat independently of the centre deck & are free to move within
operating limits.
Crush Hazard
Bystanders can be injured when machine is lowered into mowing position. Winged machines have crush points around
the hinge areas & between the wing & main body. Always use transport locking bars when not in use (winged models
only).
Rotating Blade Hazard
All persons are at risk if they place their hands or feet under the machine when it is raised from the ground when the
blades are in motion.
Pinch Hazard
Pinch points are created when two objects move together, with at least one of them moving in a circle. This hazard is
common in power transmission devices such as Belt Drives, Gear Drives & Rollers. Ensure all guarding is present.
Wrap Hazard
Any exposed, rotating machine component is a potential wrap point. Injuries usually occur when loose clothing or long
hair catch on and wrap around rotating parts such as PTO shafts or Drive shafts on the machine. Ensure all guarding
is present.
Free-wheeling parts Hazard
The heavier a revolving part is, the longer it will continue to rotate after power is shut off. This characteristic is called
‘free-wheeling.’ Blades, and various other components, drive shafts etc., will continue to move after power is shut off -
often for several minutes. Injuries occur when:
• Operators shut off equipment, and attempt to clean or adjust a machine before components have completely stopped
moving.
• Shear bolt protection device in PTO shaft shears & the mowing parts are still spinning but the primary PTO shaft is
stationary. Operator awareness is the key to safety around freewheeling parts. Never raise the machine while the
blades are still rotating.
Thrown objects Hazard
Machines throw material as a natural part of doing their job. Foreign objects, such as stones, sticks and other debris,
may be taken into this equipment and expelled at tremendous speed. These objects are contained by the sides of the
machine and by the rear/front rollers / guards / chain guards / rubber skirts depending on model of your machine.
Ensure bystanders are clear from the machine & cannot be hit with debris expelled from the machine. Bystanders or
animals in the path of thrown objects could be seriously injured. Never operate machine with decks raised from the
ground as this makes the front/rear protection redundant.
Hydraulic Hazard (if applicable)
Hydraulic systems store considerable energy. Careless servicing, adjustment, or replacement of parts can result in
serious injury. High pressure blasts of hydraulic oil can injure eyes or other body parts. The following precautions are
crucial:
• Make certain the hydraulic pump is turned off.
• Lower attached equipment to the ground.
• Conrm that load pressure is off the system.
A pinhole leak in an hydraulic hose is a serious hazard. A leak may not be visible, and the only sign may be a few drops
of uid. Never inspect hydraulic hoses with your hands, because a ne jet of hydraulic uid can pierce the skin.
Slips, Trips and Falls Hazard
Slips and falls often result from:
1. Slippery footing on the ground
2. Cluttered steps and work platforms.
The potential for slips and falls can be greatly reduced by using good judgement and practicing good housekeeping on
and around equipment.

Operating Safely
This MAJOR machine is designed to operate at a PTO rate which is stated in the Product Specications part of this
booklet. Ensure tractor PTO output is set at a correct RPM rate. This MAJOR machine must only be used for purposes
outlined in the Intended Use section of this booklet. All other use is strictly prohibited.
Users should become thoroughly familiar with the contents of this manual before using, servicing and
mounting the implement to the tractor and all other pertinent operations. Never wear jewellery, loose clothing
such as ties, scarves, belts, unbuttoned jackets or dungarees with open zips which could become caught up
in moving parts.
Always wear approved garments complying with accident prevention provisions such as non-slip shoes, ear
muffs, goggles and gauntlets. Wear a jacket with reecting stickers if the implement is used near public
highways.
Consult your retailer, the Labour Health Service or your nearest equivalent authority for the information about
the current safety provisions and specic regulations with in order to ensure personal safety.
ALWAYS DISENGAGE PTO, SWITCH OFF THE TRACTOR ENGINE AND ENGAGE THE PARKING BRAKE
BEFORE MAKING ADJUSTMENT TO THE MACHINE.
NEVER PLACE LIMBS UNDER THE MACHINE WHILE ROTOR(S) ARE TURNING. ROTOR(S) CAN
REMAIN TURNING FOR UP TO 1 MINUTE AFTER DISENGAGING PTO.
Workstation
The operator must remain seated while working the machine. If the machine is a winged unit and the wings need to
be raised/lowered the operator must not leave the tractor. Always ensure the PTO has been turned off and the parking
brake applied before leaving the tractor cab or carrying out maintenance.
NEVER OPERATE THE HYDRAULICS WITH THE TRACTOR SWITCHED OFF
Regulations for use of the transmission
The transmission to the gearboxes is protected throughout the machine by both PTO shafts and bolt down covers. All
guarding should be kept efcient and in good condition. If the condition is poor, the guarding should be renewed before
the implement is used.
UNLESS IT IS CORRECTLY PROTECTED THE TRANSMISSION COULD CAUSE DEATH SINCE IT CAN
CATCH ON PARTS OF THE BODY OR CLOTHING
Ensure retaining chains are correctly anchored on all PTO shafts, preventing them from turning. Ensure drive line can
turn easily within the shield. Keep spline grooves clean and greased so that PTO shaft can connect easily. Besides
being described in this booklet, the method by which the PTO shaft is connected to the tractor must be checked out with
the instructions in the tractor manufacturer’s manual.
Noise Hazard
Please note that the machine is normally used outdoors and that the position of the operator is seated in the driving seat
of the tractor. It is advisable to consult the prescriptions listed in tractor operator and maintenance manuals.
The acoustic pressure at a distance of 2.6m from the centre of the machine and at a height of 2.0m, with the implement
operating in a no load condition can reach 90 dBA. In a loaded condition & a PTO rate of 540 rpm the value can reach
97dBA. Higher rate of PTO input will result in in higher noise levels. Always wear hearing protection.

www.major-equipment.com 5
PTO Shaft Safety
Maximum PTO input is specied in the Product Specications section of this booklet. Contact your nearest dealer or
a specialised retail outlet if the PTO must be replaced with a longer one, since this must belong to the same power
category and possess the same characteristics. An unsuitable PTO could easily break.
The tractor PTO shaft length may be altered to suit the individual tractor model. When the machine is in operation, the
PTO shaft should have a minimum 1/3 engagement as shown in the diagrams. After the machine has been hitched to
the tractor, it should be checked in various positions that the drive line is the correct length. If the PTO is too short and
tends to slip out of place, it must be replaced with a longer one.
Driving Safely on Public Roads
Check the local Highway Code regulations before driving the tractor on public highways with an implement attached.
Check the reectors, hazard ashers and/or projecting load indicators are installed when required and efcient. These
indicators must be installed correctly and easily seen by the drivers of other vehicles.
Bystanders must not be allowed to lean against or climb onto the machine during transport or while working. Do not
allow bystanders to ride on the machine.
MAXIMUM TRANSPORT SPEED MUST NOT EXCEED 30 km/r (18 MPH)
TRAILED MODELS MAXIMUM SPEED IS 25 km/h
If the PTO shaft is too long, it should be shortened in the following way:
• Set the machine at a minimum distance from the tractor, then brake the
tractor and switch off the engine.
• Separate the two halves of the PTO. Insert the female part into the tractor
PTO and the male part into the machine PTO, checking that the position
is correct by means of the xing pins.
• Line up the two halves of the PTO together, keeping them parallel.
• Using a felt tip pen, match mark the place where the two halves must be
shortened as shown.
• First cut shield “1” and use part “2” as a reference to cut the splined shaft.
• Proceed in the same way for the second half.
• Trim and chamfer the two cut ends of the PTO and clean off all swarf
and shavings.
• Grease the two proles and join the two halves of the PTO together.
• Mount the PTO shaft and check that its length is correct as before.
Do not use the shaft cone
as a step

The machine must always be disconnected form the tractor before any cleaning, lubricating and servicing operations
can be carried out. Maintenance must be carried out by qualied personnel.
If emergency operations are required whilst the machine is connected to the tractor, switch off the engine, engage the
parking brake and disengage the PTO.
Good, regular maintenance and correct use are advised if the machine is to remain safe and long lasting.

Rollers
Check the of condition of the roller ends at the end of every season. Roller end shaft must be able to rotate freely and
without excessive play. If necessary, remove the roller end and adjust the tightness of the bearings.
Gearbox Oil
Replace oil in gearboxes after rst 100 hours and then every 400 hours thereafter.
Use oil which conforms to 80W/90 standards.
Wing shafts alignment
ENSURE THAT AFTER SERVICING THE TRANSMISSION, THE WING PTO SHAFT YOKES ARE
CORRECTLY ALIGNED AS SHOWN IN THE DIAGRAM BELOW – WINGED MODELS ONLY. IF THE
SHAFT JOURNALS ARE FITTED INCORRECTLY THE DAMAGE WILL ONLY OCCUR WHEN THE WINGS
ARE RAISED INTO TRANSPORT POSITION.

Troubleshooting
Fault Cause Remedy
Leaves a streak
of uncut or
partially cut
grass
Blades dull or bent Replace blades
Carrier RPM too low Use correct PTO speed
Field conditions are so wet that the wheels
are pushing grass into mud Too wet to mow. Stop operation and wait until it is drier
Ground speed too fast Reduce ground speed by shifting to a lower gear
Grass is down from previous weather
conditions Mow in only one direction
Possible build-up materials under machine Clean the machine
Blades mounted incorrectly (cutting edge
against direction rotation)
Change blades so that cutting edge is facing correct
rotation
Material
discharges
from machine
unevenly;
bunches of
material along
with swath
Material too high and too much material
Reduce ground speed but maintain recommended rpm
at tractor PTO or make two passes over material. Raise
machine for the rst pass and lower to desired height for
the second and cut a 90 degree angle to rst pass
Grass wet
Allow grass to dry before mowing. Slow ground speed of
tractor but keep engine running at full PTO rpm. Cutting
lower will help
Gearbox
overheating
Low on lubricant Fill to proper level
Improper type lubricant Replace with proper lubricant
Excessive grass/debris build-up around
gearbox. PTO running too fast. Remove grass, etc from machine. Lower the RPM rate
Blade is scalping
ground
Machine too low Raise machine - reset wheels
Field is ridged Cut eld at a different angle
Field is too wet Stop and wait until it is dried
Blades wear too
fast
Cutting in sandy conditions Increase cutting height
Cutting in rocky conditions Increase cutting height
Blades hitting the ground Increase cutting height
Machine seems
to require
excessive power
Advancing into grass too rapidly Reduce forward travel speed
Hitting ground Raise machine and reset wheels
Worn or dull blades Sharpen or replace blades
Excessive
vibration
Check gearbox bolts Tighten if loose
Check for loose nuts on blades Tighten if loose
Blade broken Replace blades, in set
New blade or bolts matched with worn blade
or bolts Replace blades or bolts in sets
Drivelines not phased correctly. Implement
and tractor yokes must be in line Phase the driveline. Replace if necessary
Noisy machine
Low oil in gearbox Check level and add oil
Loose Parts Check all bolts are fully tightened
Wrong PTO rpm rate Check PTO rate & adjust as necessary
Rotors bent/broken Replace bent or missing blades
Bent PTO shaft Check PTO shaft aligned correctly
Bent gearbox shaft Check output shaft on gearboxes are not bent
Check driveline between gearboxes is aligned
