Info

The New Holland TR 70, introduced in 1975, was the world’s first Twin Rotor combine harvester. In the Twin Rotor system, two longitudinally arranged, counter-rotating rotors replaced the conventional threshing drum and concaves. The rotor dimensions were nailed right from the start and remained unchanged even in the final TR models produced in the early 2000s.

The TR 70 came with a mechanical gearbox and was offered with either a Caterpillar V8 engine (165 hp) or a turbocharged Ford 6-cylinder (145 hp). Its pillar-less cab was cutting-edge for its day, and an electronic system for monitoring all key functions was available as an optional extra.
