The variable power-split s-matic transmission has 75% more traction than its predecessor and provides speed independent and with 1450 r / min at 40 km / h more fuel-efficient driving. Your advantage: the perfect adjustment of speed and power train, high efficiency and optimum efficiency without any interruption. And the transfer case completely developed and built by Werner enables the integration of a gearbox or motor-dependent PTO and ground speed PTO, available with full engine power.

Werner WF Trac

In addition to the powerful engine and the ergonomic rotation of the WF trac cabin is equipped with a highly advanced, infinitely variable power-split-s automatic transmission. For working without interruptions in tractive power, high-efficiency and high cost.

The drive unit is equipped with a 6-cylinder engine (238 hp, 7.2 liters, 850 Nm) of Mercedes MTU and is on the road with 50 km / h faster than any other forestry vehicles. WF trac has a modern SCR catalytic converter and AdBlue technology and meets Euromot 3B. This represents a fuel saving of 15 to 20% and particularly favorable 0.5 liters per cubic meter.

The interior of the 270ยบ rotating cabin of the WF trac located at the middle of the vehicle is a more spacious and tidy workplace which has been designed according to ergonomic principles.

The features and functions of the cabin turn it into a modern and tidy workplace where all vehicle functions are controlled by a central operating element. A spacious plough window provides a view of the vehicle with the air-conditioning ensuring optimal working conditions in all kinds of weather. The vehicle interior also has room for a second seat and ample storage space as well as a refrigerating compartment.
