The 73.5kW/100hp Valtra-Valmet 6550 HiTech is a tractor with many strengths: Grunty engine, robust axles and running gear, easy-to-operate gearbox and a comfy cab. Out in the field it also performs well – although, like most machines, there is the odd downside, too. In this tractor test we examine the 6550’s pluses and minuses.
