Agritechnica 2011: Electricity-generating tractor transmission

German gearbox builder ZF has produced an innovative tractor transmission which produces electric power to drive implements rather than a pto.

The prototype system has been constructed using standard components and uses an electric generator from an industrial vehicle. ZF reckons the generator could have significant benefits over mechanical drive and is carrying out a series of tests to see how it performs.

A Deutz-Fahr tractor has already been fitted with the transmission and it is being trialled with an electrically-powered trailer from Fliegl and drill from Amazone.
