4.6 PTO DRIVE SHAFT COUPLING
Before mounting the PTO drive shaft, the operator must read the use and
maintenance manual of the PTO drive shaft and the tractor; therefore, ensure
that the number of revolutions and the direction of rotation of the tractor PTO
correspond to those of the mower. Otherwise, contact support.
WARNING:
Use PTO shafts with adequate power transmission capacity.
THE FOLLOWING OPERATIONS MUST BE CARRIED OUT BY SPECIALIST
OPERATORS.
Check that the minimum and maximum length of the PTO drive shaft are those
required by the mower-tractor coupling.
Remember that when at maximum extension, the pipes must overlap at least
1/3 of the length of the internal pipe. Moreover, in the maximum closure position
of the pipes, the minimum clearance allowed of the plastic protections must be
at least 2 cm. in order to prevent damage to the protections and to the gear
transmission.
If this is not the case it is necessary to shorten it appropriately, cutting it as
necessary; consult the use and maintenance manual of the PTO shaft or contact
the authorised dealer who will perform this.
• Position the shaft in the right direction, making reference to the gure of the
tractor embossed on the external protection pipe.
• Insert the rst hub of the PTO shaft on the mower's PTO shaft while keeping
the fork safety pin or collar fully pressed; release the pin or collar and move
the PTO drive shaft back until it engages with an audible "click” in its housing.
• Then repeat the operation with the opposite hub of the shaft, inserting it into
the tractor PTO.
• Then hook the snap hook of the retaining chains of the PTO drive shaft
protection into the seat of the driveline shield on the mower PTO as shown.
• Do the same on the PTO of the tractor.
