Operating Safely
This machine is a result of continuous research, development and quality testing. Please treat it accordingly.
The MAJOR TDR Rollermower is designed to operate at 540 RPM. Ensure tractor PTO output is set at
540 RPM. The MAJOR TDR Rollermower must only be used for cutting grass. Moreover, it must only
be used with a suitable tractor (see product specications) 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 nonslip 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 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
operator 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 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 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 RPM 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 TDR 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 TDR Rollermower 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.
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
implement. 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 for the implement is 30km/h. DO NOT EXCEED
• Check machine is hitched to the tractor as described. Ensure the tractor parking brake is applied
• Lift the two wings by hydraulic control & lock in position using the wing locking clamps.
• Use the retaining strap to fully secure wings.
• Lift the rear deck by hydraulic control and lock hydraulic pipes via the shutoff taps supplied for the rear deck.
• Attach hydraulic connections (check tractor manual for correct hydraulic layout i.e. open or closed circuits). The
TDR Gang Mower is factory set for ‘open’ hydraulic circuits.
• Attach 12v lighting connection
