Page 24: Pto Driveshaft Installation
PTO DRIVESHAFT INSTALLATION The PTO driveshaft attaches between the tractor and the machine gearbox to transfer the power required to the run and operate the machine – it is important to achieve the correct shaft length to avoid risk of it ‘bottoming out’ when raising or lowering the machine. The procedure for measuring and cutting the shaft is as follows: Measuring the PTO Shaft... -
Page 25: Fitting Operator Control Units
FITTING OPERATOR CONTROL UNITS Fitment of the operator controls in the tractor cab will vary depending on the particular model or specification of machine – the information below lists the differing methods of fitment for the various types of controls available. NOTE: Electric control units work within the range of 12v-16v DC and will require a minimum power supply of 12v DC. -
Page 26: Hydraulic Oil
HYDRAULIC OIL Hydraulic Oil Reservoir Fill the tank with oil selected from the chart below or a good quality equivalent to a point where the level is between the minimum and maximum marks on the tank gauge. When the machine is initially run the level will drop as the oil is drawn into the circuit - top back up as required to the correct level on the gauge. -

Page 33: Transport Position
TRANSPORT POSITION For transport on the public highway the flailhead, or cutterbar, must be folded within the overall width of the tractor. To allow the machine to be compactly folded the base of the breakaway ram and its fixing pins must be transferred from the outboard work position (A) and relocated to the inboard transport position (B) - see illustration opposite. -
Page 34: Operation
OPERATION Operator Guard Machine Guards Before each period of work, check that all the relevant tractor and machine guards are in place and in good working condition. Small splits and abrasions on the lower edges of the flail head rubber flaps are permissible, but should one or more of these cuts or splits become fifty per cent or more of the flap height they should be replaced immediately as they will have become ineffective for debris containment. -
Page 35: Running Up Procedure
RUNNING UP PROCEDURE CAUTION: Before initial use of a new machine, all lubrication points must be greased and the gearbox and oil tank levels checked and where required topped up before attempting to use the machine. Refer to maintenance section for details. Semi-Independent (SI) Models ... -
Page 36: Reversing Rotation (Semi-Independent Machines)
ROTOR OPERATION – Reversing Rotation TI Machines Depending on the particular build, rotor operation on machines with independent hydraulic systems will either be via a cable operated rotor control lever or by operation of the rotor control switch on the machines control unit – refer to the previous controls section for specific details of operation. -
Page 37: Operating Speeds
OPERATING SPEEDS PTO Operating Speed The correct PTO speeds for operation of these machines is: 500 – 540RPM NOTE: For cutterbars 500 rpm is a guide speed only – it should be run only as fast as necessary perform required job. Never exceed 540 rpm PTO speed. -
Page 38: Breakaway Protection System
BREAKAWAY PROTECTION SYSTEM The machine is fitted with a hydraulic breakaway device which protects the structure of the machine should an unforeseen obstacle be encountered. The breakaway system on these machines is in the form of a pivoted dipper arm and breakaway ram. -
Page 39: Lift Float Kit
LIFT FLOAT (Optional Extra for Ground Work) Work without lift float requires far more concentration and input from the operator to quickly react and re-adjust to the ground contours often resulting in patches of higher cut material where the head is cutting too high and ‘scalping’ of the ground where it is cutting too low – in the case of the latter this can lead to increased flail wear, damage or even loss of flails. -
Page 40: Hazards & Dangers
HAZARDS & DANGERS Adverse Slopes When working with the flailhead high and reach fully in it is possible for the main arm balance to go over centre and take the weight off the lift ram. A restrictor in the gland circuit of the lift ram will prevent sudden unpredictable movements if this should occur - for reasons of safety this restrictor should not be removed. -
Page 41: Overhead Power Lines
OVERHEAD POWER LINES DANGER! It cannot be stressed enough the dangers involved when working in the vicinity of overhead power cables. Some of our machines are capable of reach in excess of 8 metres (26’) therefore they have the potential to well exceed, by possibly 3 metres (9’ 9”), the lowest legal minimum height of 5.2 metres from the ground for 11,000 and 33,000 volt power lines. -
Page 42: Hedgecutting Procedure
HEDGECUTTING PROCEDURE Cut the side and bottom of the field side first. This leaves the maximum thickness of hedge on the road side to prevent the possibility of any debris being thrown through the hedge into the path of oncoming vehicles. Cut the side and bottom of the road side. -
Page 43: General Maintenance
GENERAL MAINTENANCE General Lubrication The illustration below indicates the general locations of lubrication points - all points should be greased on a daily basis and prior storage of the machine. New machines must be greased prior to first use.

Page 45: Hydraulic System
HYDRAULIC SYSTEM Oil Supply Check the oil level in the reservoir daily. Oil Condition & Replacement No fixed time period can be quoted for oil changes as operating conditions can vary widely but a visually inspection of the oil will often indicate its current overall state. Signs of a reduction in its condition will be apparent by changes in colour and appearance when compared to new oil. -
Page 46: Hydraulic Hoses
HYDRAULIC HOSES The condition of all hoses should be carefully checked during routine service of the machine. Hoses that have been chaffed or damaged on their outer casing should be securely wrapped with waterproof adhesive tape to stop the metal braid from rusting. Hoses that have suffered damage to the metal braid should be changed at the earliest opportunity. -
Page 47: Pto Shaft Maintenance
PTO SHAFT MAINTENANCE PTO Shaft Lubrication The PTO shaft should be lubricated on a regular basis using lithium based grease – each end of the shaft has 2 greasing points; one for lubrication of the universal joint and one for lubricating the rotating fixing ring of the shaft shield –... - Page 48 TORQUE SETTINGS FOR FASTENERS The chart below lists the correct tightening torque for fasteners. This chart should be referred to when tightening or replacing bolts in order to determine the grade of bolt and the correct torque unless specific torque values are assigned in the text of the manual. Recommended torque is quoted in Foot-Pounds and Newton-Metres within this manual.
