As a tractor, the Valtra Classic T121 belongs to the Valtra 4WD Tractor series. Under the bonnet works a six-cylinder engine displacing 6.6 litres, producing 141 hp (99.2 kW). Rated power arrives at 2,200 rpm — the engine pulls from low down rather than needing to be revved.
It will not go faster than 40 km/h — a working pace, not a travelling one. Unladen, it tips the scales at 5,650 kg.
Within the range, rated power spans from 52.7 to 280 hp; with 141 hp, the Classic T121 sits in the mid-field. Directly alongside are the HiTech N121 with 139 hp below and the N141 HiTech with 152 hp above.
