TERRAMATIC CVT Transmissions
The new generation of continuously variable tractor transmissions
Key Facts
What can TERRAMATIC CVT Transmissions provide?
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 by a new concept making vehicle operation even more efficient and resource-saving. 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. Almost all renowned tractor manufacturers use continuously variable transmissions from ZF. 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 unrivaled 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. Operational errors are almost eliminated. Since no shifting operations are required the drivers can completely concentrate on their work.
But also in economic terms continuously variable transmissions are unbeatable for large-scale agricultural work. They stand out by optimum utilization of engine power at maximum productivity and minimum consumption. 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. About 5% consumption savings can be achieved on the tractor through power-on-demand operation of electrical auxiliaries, along with boosted productivity and tractive effort, as well as reduced COâ‚‚ emissions.
- Up to 80 kW continuous electric power
- Minimum effect on the existing vehilce architecture
- Transmission downsizing possible
