Lower the machine to the ground. Adjust the top link (A) to the minimum cutting height as shown
at (B).
PTO shaft
Only use a tractor PTO shaft set for 540 rpm operation. It is dangerous to cou-
ple a tractor with 1000 rpm PTO output to a machine intended for 540 rpm PTO
input speed.
When fitting the first time, before checking the shaft length, the top link must be adjusted to mini-
mum cutting height (short top link). Follow this procedure:
• Adjust the linkage so that the PTO stub shafts are level.
• Fit the two parts of the PTO shaft onto the shafts of the tractor and the machine respectively.
The clutch is placed at the machine end (C).
• Place the two shaft halves together as shown at (D) and mark the shortening length (about 40 mm
(1-1/2”) clearance).
NOTE: Some tractor types do not require a shortening of the shaft.
Shortening of the shaft
When shortening the PTO shaft the four parts a - b - c - d must be shortened equally. After short-
ening, the tube ends and the shaft ends have to be filed off, cleaned of filings and lubricated.
Checking of PTO shaft length
NOTICE
Fit the shortened shaft. Carefully check that the shaft does not bottom when the linkage is raised
or lowered. Also check that the sliding tubes overlap with at least 150 mm (6”), when the machine
is in the working position.
This check should always be carried out when the machine is coupled to the tractor. If the tractor
is replaced the above check must be carried out and if necessary a new adaptation of the shaft
must be done.

IMPORTANT
PTO ADAPTERS SHOULD NOT BE USED WITH ANY BUSH HOG
EQUIPMENT. FAILURE TO FOLLOW THESE INSTRUCTIONS WILL
CAUSE DRIVELINE FAILURE AND POSSIBLE TRACTOR DAMAGE.
