The Valtra Shell Pulling Team competes with three Pro Stock tractors in Europe Team concentrates on the 3.5ton Pro Stock Class with three tractors. Only diesel tractors race in this class. The race tractors of the Herlevi team are based on the Valtra T190 tractors of 200 hp. The basic structure of the Pro Stock tractor is very similar to a standard tractor and for example the reliable Valtra Delta Powershift can be used in tractor pullers to change the speed ratios under the load.

The tractors of the team are powered with a SisuDiesel 74 ETA Fortius engine. These pro Stock tractors can generate well over 2 000 hp with just one single turbocharger. 

As a whole, Valtra’s competition actions support the product development by giving an important knowledge on extreme loading conditions.
