Setting Up & Adjustment - McConnel MERLIN Xtreme Offset Operator's & Parts Manual

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. It is
important the rotor rotates in the correct direction for cutting.
540RPM or 1000RPM
If necessary, the drive and rotor pulleys on the machine can be swapped, top to bottom, to
configure the machine to suit a particular PTO output speed of the tractor being used.
If the tractor has only 540 RPM PTO:
The larger pulley should drive the smaller pulley to
act as an increaser.
If the tractor has only 1000 RPM PTO:
The smaller pulley should drive the larger pulley to
act as a reducer.
Never operate the PTO at 1000RPM with the
larger pulley driving the smaller gearbox pulley
- this will drive the rotor at higher speed resulting in
severe damage to the machine.
