ZF unveils eTERRADRIVE for electric tractors
The new driveline system marks what the company calls “a significant step towards zero-emission agricultural machinery”. It is a fully electric transaxle unit that integrates traction, power take-offs, and rear lift in a single housing. This enables a seamless power flow and optimised energy use across multiple functions while maintaining full tractor capability.
According to ZF, the system’s modular structure allows it to be used across a wide range of agricultural applications – from specialty crop operations to municipal fleets and conventional farming. ZF engineers focused on a compact design that simplifies integration across vehicle platforms and track widths, while the smaller footprint and flexible design can accommodate larger battery packs or hydrogen storage systems.
At the core of the eTERRADRIVE are two oil-cooled synchronous motors combined with an integrated planetary gear set. This layout is said to improve operating efficiency, allow precise torque control, and enable demand-based energy management. Compared with conventional electrified tractors that often adapt hydrostatic CVT systems, the ZF solution reduces mechanical complexity and enhances efficiency through direct electric drive and recuperation.
The system architecture also includes an advanced electronic control unit (eDCU) that coordinates with existing control systems such as TCU and VDC. The company noted that the control platform “integrates safety-relevant functions to meet high-voltage requirements in off-highway applications”, ensuring compliance with current and future safety standards.
