SECTION 00 -- GENERAL INFORMATION -- CHAPTER 1
00-6
7. The PTO assembly must be fitted to the tractor
being used. The tubes must overlap at least 102
mm (4 in). At the same time, the tubes, 1 and 2,
must be short enough so they do not bottom out.
The assembly must also be long enough so it
does not pull apart when the breakaway system,
1, operates.
NOTICE: Most tractors will not require the PTO to be
shortened.
Separate the front and rear PTO shafts. Connect
the front half to the tractor PTO and the rear half to
the disc mower input shaft. Raise and lower the
machine to find the position where the PTO would
be the shortest. Hold the shafts side by side and
mark the length to provide 10 mm (3/8 in)
clearance between the end of the shafts and the
yoke.
Measure how much is to be cut from your marks.
Cut off an equal length from the front and rear
plastic shield. Shorten the PTO telescoping
shafts the same amount as the plastic shields.
NOTICE: Remove the grease sleeve from the rear
half of the PTO shaft before shortening the tube.
Remove the burrs from the shaft ends with a file or
grinder. Clean out the metal chips and filings.
Apply grease to the inside of the outer telescoping
tube before assembly. Reinstall the grease
sleeve on the end of the rear half of the PTO shaft.
Check to be sure the shafts do not bottom out, and
operate the breakaway to be sure they do not
come apart.
