German automotive supplier ZF introduced its new eTERRADRIVE, a fully electric transaxle system for tractors, at Agritechnica 2025 in Hanover. Designed for agricultural machines in the 60 to 100 kW power range, the unit is compatible with existing tractor interfaces and standards, offering manufacturers a plug-in pathway toward electrification.
ZF described the eTERRADRIVE as “a significant step towards zero-emission agricultural machinery.” The integrated driveline combines traction, power take-offs, and rear lift in a single housing, ensuring a seamless power flow and optimized energy use across multiple tractor functions while maintaining full utility.
Built around a modular architecture, the eTERRADRIVE can be applied across various agricultural operations, including specialty crop management, municipal services, and traditional farming. Engineers designed the compact system to simplify installation on different vehicle platforms and track widths, while its smaller footprint leaves room for larger battery packs or hydrogen storage systems.
At its core, the eTERRADRIVE uses two oil-cooled synchronous motors coupled with an integrated planetary gear set, delivering high efficiency, precise torque control, and on-demand energy management. ZF said the configuration eliminates much of the mechanical complexity found in hydrostatic CVT systems, increasing overall drivetrain efficiency through direct electric drive and regenerative braking.

The system also features an advanced electronic drive control unit (eDCU) that interfaces with vehicle systems such as the transmission control unit (TCU) and vehicle dynamics control (VDC). ZF noted that the control platform “integrates safety-relevant functions to meet high-voltage requirements in off-highway applications,” ensuring compliance with evolving safety standards for electric agricultural equipment.
