TERRAMATIC CVT Transmissions

The new generation of continuously variable tractor transmissions

Key Facts

Lightweight designdesigned for efficient operationModular designsimplified adaption to different vehicle conceptsMaintenance-friendlyeasy servicing

Continuously variable transmissions (CVTs) of the TERRAMATIC® series are designed for tractors of up to 400 HP. Efficiency has been further improved and maintenance has been simplified supporting efficient vehicle operation and simplified maintenance. While speeds were reduced, the transferable torque could be further increased which ideally meets the demands resulting from the "Tier 4" Emission Directive.

CVT Technology from ZF

Even if agricultural machines appear large and cumbersome, they must apply their force and power precisely and in a well-dosed manner. ZF driveline technology ensures the necessary sensitiveness for these requirements. In particular, their reliability, efficiency and ease of operation are highly regarded on the market.

Movement sequences flow easier using continuously variable transmissions from ZF, thus enabling an even more precise control of agricultural machines. Due to the fact that manual shifting is no longer necessary, the drop in power associated with gear changing does not occur. Four driving ranges are automatically shifted with high efficiency. The ratios are selected to steplessly cover the speed range from 0 to 60 km/h.

Also farmers benefit from the continuously variable technology, especially in difficult driving situations: The continuously variable transmission ratio enables moving-off and stopping on a slope without using the clutch or brakes. The likelihood of operating errors can be reduced. Since no shifting operations are required the drivers can completely concentrate on their work.

But also in economic terms continuously variable transmissions are well suited for large-scale agricultural work. They stand out by efficient utilization of engine power for a wide range of applications. In addition, their modular and compact design allows easy integration into many different vehicle concepts.

TERRACOM – Condition Monitoring

Using today’s vehicle and Transaxle infrastructure (installed sensors and actuators) to monitor the systems behavior and utilization to derive the system and its component condition and to perform a prediction or reaction.

Goals of ZF TERRACOM

Reduce vehicle downtime in case of failure and damage
Foster knowledge basis for future driveline development
Streamline warranty processing - increase transparency of root-cause(s) and support aftermarket services with instant overview

TERRA+ Integrated Generator Systems

High and low voltage generator system for CVT tractor transmissions

The system comprises an efficient electrical machine which is integrated into the transmission housing. Power supplied by the engine is converted into electric power and can be used directly on the implement or on the tractor.

The power-on-demand operation of electrical auxiliaries supports efficient energy usage in the tractor. In addition, electrical power can be supplied directly to implements or vehicle functions.
