The URBAN TR75 logger is supported on the three-point hitch of the tractor. It is designed especially for small tractors, but can be used without a problem even under a strong tractor. The optimum power of the tractor is 25 hp and more, the minimum power is 15 hp.
The TR75 differs from the TR70 type by featuring a V-belt drive. The V-belt drive serves as shock-absorber and also acts as an overload clutch, which is not needed for this type. The large 90 kg pulley serves as a flywheel, which also contributes to shock absorption and smoother running. The torque on the TR75 cardan is half compared to TR70 (with processing the same branch diameter).
