The length of the PTO shaft is suitable for all known tractor conditions. However the
PTO shaft must be checked/altered to suit the tractor combination it is being fitted to.
First, fit the PTO shaft to the machine and then check if the PTO can be connected to
the tractor stub. If not, then the PTO shaft is too long and must be altered. Typically the
shortest distance on a trailed machine is when the tractor is turned at the maximum
angle from the machine. Operating on very hilly ground can also reduce this further.
The shortest distance on a linkage machine is when the PTO stubs of both tractor and
machine are aligned horizontally.
(See ‘Adjusting the PTO shaft to the tractor’)
After measuring carefully, the PTO shaft halves should be cut equally so that the PTO
shaft assembly is kept as long as possible, whilst just allowing enough room for its
removal. This will ensure that a maximum overlap (ideally 200 mm minimum) is
maintained, when extended. Maximum 80° angle of movement should never be
exceeded, otherwise permanent damage will result.
