Following an extensive test programme, Zuidberg’s new High Efficiency Front PTO gearbox, is now commercially available on a wide range of tractor models.
The transmission differs from conventional front PTO system design in that the clutch is now positioned on the input shaft. The re-siting of the clutch ensures that the inside of the transmission only rotates if the clutch is actually engaged, keeping energy losses to a minimum. Moreover, it
facilitates a much more compact design for the entire transmission unit.
The new High Efficiency PTO is equipped with an integrated load sensor that transmits a signal to manage power to the PTO and subsequently the tractor implement, protecting against overload and potential damage. This signal, either digital or analogue, can be used as an input signal for the tractor ECU to either trigger a warning or limit engine power.
Internal oil management has also been optimised, resulting in lower resistance and higher efficiency without compromising the lubrication of internal components. The transmission can transfer power levels up to 150 kW (201 Hp) at an output speed of 1000 rpm from a more compact unit.
