  • Page 23: Attaching To Tractor

    ATTACHING TO TRACTOR Fit the machine to the tractor linkage in the standard way, ensuring the correct match of linkage (CAT 2 pins).

Use stabilizers to take any free movement out of lower link arms.

  • 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: Setting Up & Adjustment

    SETTING UP & ADJUSTMENT Hydraulic Offset The machine can be moved into a variety of settings from the central position to fully offset by operation of the tractors’ external spool valve. Front Linkage Mounting Tractor front PTO’s do not have standard rotation so it may be necessary to turn the gearbox through 180 degrees (top to bottom), to compensate for this irregularity.

  • Page 26: Operation

    OPERATION Engage the PTO only when the tractor engine is at low revs to prevent shock damage to machine components. Slowly increase the engine revs to achieve the standard 1000/540 RPM PTO speed as indicated by the machines speed decal. CAUTION: If at any time serious vibration occurs, stop the engine immediately and following all safety precautions check the rotor for missing or damaged flails.
