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 float 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 Mowers 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.’ Rotary mower 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
• When shear bolt protection device in PTO shaft shears & the rotors 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
Rollermowers 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 rear
roller & the sides of 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 rear roller deflector redundant.
Hydraulic Hazard
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.
• Confirm 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 fluid. Never inspect hydraulic hoses with your hands, because a fine jet of hydraulic fluid 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.

4www.major-equipment.com
Operating Safely
The MAJOR Rollermower is designed to operate at 540 RPM. Ensure tractor PTO output is set at 540 RPM. The
MAJOR Rollermower must only be used for cutting grass. Moreover, it must only be used with a suitable tractor (see
product specifications) and driven by an adequate drive-line by the tractor PTO. 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 reflecting 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 cur-
rent safety provisions and specific regulations with in order to ensure personal safety.
ALWAYS DISENGAGE PTO, SWITCH OFF THE TRACTOR ENGINE AND ENGAGE THE PARKING BRAKE BE-
FORE MAKING ADJUSTMENT TO THE MACHINE.
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 was measured 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 - 90 dBA. In a loaded condition & a PTO rate of 540 rpm the
obtained value was 97dBA.

5
www.major-equipment.com
NEVER PLACE LIMBS UNDER THE MACHINE WHILE ROTORS ARE TURNING. ROTORS CAN REMAIN
TURNING FOR UP TO 1 MINUTE AFTER DISENGAGING PTO.
Workstation
The operator must remain seated while working the machine. When the wings need to be raised and lowered the op-
erator must leave the tractor. Always ensure the PTO has been turned off and the parking brake applied before leaving
the tractor cab. The operator must always apply the parking brake, and turn off the engine before leaving machine 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 efficient 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 form 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 manual, 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.
PTO Shaft Safety
MAX PTO INPUT 540 R.P.M. 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 char-
acteristics. 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 Rollermower 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.
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 Rollermower PTO, checking that the position is correct by means
of the fixing 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 profiles and join the two halves of the PTO together.
• Mount the PTO shaft and check that its length is correct as before.

6www.major-equipment.com
The shaft must not reach the end of the tube or project from this. Ensure the PTO does not bottom when turning
Driving Safely on Public Roads
Check the local Highway Code regulations before driving the tractor on public highways with a towed imple-
ment. Check the reflectors, hazard flashers and/or projecting load indicators are installed when required and
efficient. 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 19Km/Hr (12 MPH)
Noise Levels:
The acoustic pressure was measured 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 - 90 dBA. In a loaded condition & a PTO rate of 700 rpm
the obtained value was 97dBA. It is advisable to consult the prescriptions listed in tractor operator and maintenance
manuals.
Operating the Machine
Inspections before Use
Always disengage PTO, Switch off tractor engine and engage the parking brake before making adjustment
to the machine.
