ZF Presented the eTERRADRIVE, a Compact and Modular Electric Transmission That Delivers Up to 100 kW, Works in New or Current Tractors, and Promises More Efficiency, Autonomy, and Completely Emission-Free Operation in the Field
The transition to cleaner alternatives goes beyond the roads. Agricultural machinery also has significant impacts because it operates in direct contact with the soil, nature, and food.
ZF decided to tackle this reality by introducing the eTERRADRIVE, a modular electric transmission designed for tractors that seek to replace diesel with more sustainable solutions.
A Compact System Focused on Agricultural Electrification
The company explains that the eTERRADRIVE delivers power between 60 and 100 kW and only uses one drive unit. The system includes mechanical power take-offs, a work hydraulic set, and a rear lift, essential features for those who depend on performance in the field.

According to ZF, its compact dimensions have been designed for smaller vehicles within the sector. This format caters to various applications as it offers flexibility for installation on different platforms and widths, expanding usage possibilities.
Compatibility with New and Current Tractors
The company’s proposal goes beyond developing new equipment. ZF claims that the eTERRADRIVE works in both new vehicles and models already available on the market. This compatibility with existing interfaces facilitates the adoption of the technology by avoiding extensive redesigns on operating machines.
As a result, manufacturers and operators find a practical alternative to advance electrification. Thus, they can maintain their current product lines while introducing cleaner and more efficient versions without high adaptation costs.
Advanced Electronics and Focus on Safety
To optimize functionality, the system incorporates an electronic architecture that uses an additional control unit. This eDCU communicates with the tractor’s systems, including transmission control and the module responsible for vehicle dynamics.
The company also emphasizes that it has integrated specific features for safety in high-voltage environments. These mechanisms meet the needs of off-road operations, where conditions require robustness and quick responses to protect the equipment and the operator.
An Alternative to the Traditional Model of Electric Tractors
Electric tractors frequently use hydrostatic CVT transmissions, a solution that replaces the combustion engine with an electric motor. Although straightforward, this approach has limitations. ZF points out greater mechanical complexity, energy losses, and scalability challenges as factors that hinder performance.
The eTERRADRIVE aims to eliminate these issues by combining two oil-cooled synchronous motors with a planetary gear set. This integration enhances efficiency, improves torque control, and optimizes energy use during field operation.
Additionally, the compact design frees up space to store more energy. Thus, the tractor can accommodate larger batteries or hydrogen tanks, increasing autonomy and ensuring prolonged use in various types of agricultural activities.
All Functions with Zero Emission
Even with its electric proposition, the system maintains all functionalities of a traditional tractor. The eTERRADRIVE enables energy recovery while working, preserves power and performance, and operates with zero emissions, which is significant for those seeking to reduce environmental impacts.
ZF summarizes the main advantages of the system in five points: emission-free operation, reduced mechanical complexity, enhanced energy efficiency, scalable platform, and total compatibility with current safety standards and interfaces.
