PTO
Place the PTO shaft in its support and connect it to the machine input shaft and to the tractor PTO (the outside PTO
shaft guard nearest the tractor). The PTO shaft must always be located inside its support during work.
Make sure PTO shaft length is correct :
1) When the PTO shaft is in its maximum extended position, a minimum tube overlap of 300 mm (12") must be
maintained.
2) When the PTO shaft is in its maximum overlap position (retracted), tubes must not butt against the yokes. As
a safety measure a clearance of at least 2 cm (0.8") must be maintained. If this is not the case, shorten the two
transmission tubes and the two guard tubes by the same length (photo A and B). Bevel and clean the tubes
(photo C) and grease the inside of the outer tube (photo D).
3) Never operate the PTO at too great an angle (30° maximum).
These recommendations and adjustments must be respected to avoid damage or premature wear
of the PTO shaft.
Before operating the machine, double check that the gearbox setting matches the selected tractor
PTO speed and PTO direction of rotation.
To avoid accidents which could be serious, make sure that the guards are always correctly in place
and secured with the safety chains provided. Damaged guards should be replaced immediately.
