SIPMA PTO shafts are designed to transmit
a specific torque from the Power-Take-Off spline shaft of the tractor to the Power-Take-On spline shaft of the machine. SIPMA S.A. makes PTO shafts designed to transmit the torque of the following ranges: 220 Nm, 300 Nm, 460 Nm, 540 Nm, 630 Nm, 680 Nm, 900 Nm, 1200 Nm and 1700 Nm in the basic version, and  680 Nm in wide angle version, in two options:
  • with one wide angle joint, 
  • with two wide angle joints.

Basic PTO shafts are used when the mutual location of the Power-Take-Off and Power-Take-On spline shafts during continuous works does not result in exceeded 25° of joint breaking angle.

Wide angle PTO shafts are used in the case where the fracture of relative position of the tractor power take off to the machine power input connection shaft can allow reaching up to 50° angles in every working moment and 80° angles temporary. These shafts allow the transfer of power constantly without having to drive off at the headland.

Basic and wide angle PTO shafts, depending on needs,  may be equipped in the following safety cluthches:

  • overrunning,
  • friction,
  • overload automatic clutch,
  • friction and overrunning ,
  • overload clutch with scoops operating radially,
  • with shear bolt.

The overrunning clutch (SJ) transmits the torque in one direction only and is used in PTO shafts which drive machines with elements having high inertia (e.g. disc mowers).

The friction clutch (SC) transmits torque without switching off the drive when the overload reaches the set value. It can be used as a starting or overload clutch for machines with elements having high inertia.

The overload automatic clutch (SPA) is used to interrupt the power flow when the transmitted torque reaches a preset size. The clutch does not require the immediate shutdown of the drive at the time of the overload occurs.

The friction and overrunning clutch (SD) allows for the torque transmission without switching of the drive, even under overload conditions exceeding the maximum clutch setting. At the same time, it allows the torque transmission in one direction only. It can be used for machines with elements having high inertia.

The overload clutch (SP) with scoops operating radially operates by interrupting the drive transmission when the torque exceeds the clutch setting.

The clutch with shear bolt (SK) protects the driveline against blockage and disconnects the torque transmission from the tractor when the torque exceeds the clutch setting which breaks the bolt.
