Page 32: Pto Driveshaft Installation
PTO DRIVESHAFT INSTALLATION The PTO driveshaft attaches between the tracto r and the machine gearbox to trans fer the power required to the r un 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 41: Flailhead Attachment
FLAILHEAD ATTACHMENT For ease of attachment and safety this procedure is best performed on a firm level site. 1) With the tractor parked alongside the flailhead operate the controls of the machine to position the clamp bracket on the machine’s head angling mechanism directly behind the flailhead at a suitable height for attachment. -
Page 42: 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 43: 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 44: Reversing Rotation (Si 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 45: Emergency Stopping
EMERGENCY STOPPING In all emergency situations machine operation and functions must be stopped immediately; Stop PTO operation using the tractor controls then immediately kill electrical power to the machine using the Off (Emergency Stop) switch on the machine’s control unit. WARNING: Auto-Reset Machines When the Auto-Reset feature is active the machines arm set is capable of unintentional movement even when the PTO is switched off and stationary. -
Page 46: 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 47: 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 48: 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 49: 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 50: Overhead Power Lines
OVERHEAD POWER LINES (OHPLs) It cannot be stressed enough the dangers involved when working in the vicinity of Overhead Power Lines (OHPLs). Some of our machines are capable of reach in excess of 8 metres (26’); 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 51 Definitions of Exclusion Zones Risk Assessment Before starting to work near OHPLs you should always assess the risks. The following points should be observed; Know the risks of contacting OHPLs and the risk of flashover. Find out the maximum height and maximum vertical reach of your machine. ...

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 53: 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 and PTO shaft must be greased prior to first use. Gearbox Lubrication Refill the gearbox after an initial 50 hours of use and thereafter at annual or 500 hour intervals, whichever occurs earliest. - Page 54 SERVICE SCHEDULE Every Day Grease machine fully prior to work (and prior to storage). NOTE: New machines must be fully greased before initial use. Check for broken or damaged flails. Check tightness of flail nuts and bolts. ...

Page 55: 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. -
