Page 33: Cutterbar Operation
CUTTERBAR OPERATION Tractor Control Settings Refer to the tractor’s hand book to ascertain the correct control settings to suit the type of machine and the hydraulic installation. Operational Limitations The cutterbar is a light hedge trimming tool - attempting to cut unsuitable material will cause the knife to stall resulting in the tractors relief valve blowing and overheated oil. -
Page 34: Pre-Work Preparation & Precautions
PRE-WORK PREPARATION & PRECAUTIONS IMPORTANT: Always read the book first before attempting to operate the machine – practise operating the machine, without the rotor running, in a safe open space until you are fully familiar with all controls and functions of the machine. Only begin using the machine for work when you are confident that you have mastered the controls and operation sufficient for safe use of the machine. -
Page 35: Breakaway
BREAKAWAY The machine is fitted with a hydraulic breakaway device which protects the structure of the machine should an unforeseen obstacle be encountered. The pivoted arm is held in the working position by the oil pressure in the fully extended breakaway ram. -
Page 36: Lift Float - Optional Extra
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 –... -
Page 37: 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 38: 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 39: 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 40: Flail Types
FLAIL TYPES Grass Flails Designed specifically for general mowing activities – low power usage, ideal for cutting materials of low density.
