Volvo BM – other models: the collective page of the Eskilstuna tractors outside the named ranges, from the two-cylinder BM 810 to 860 through BM Valmet 605 to 905 to the BM 2650H, 23 to 122 kW, Perkins and Volvo engines
This page gathers the Volvo BM tractors the register could not assign to a named range – from the two-cylinder classics of the BM 810 to 860 range to the larger BM Valmet models. Volvo BM traces back to Bolinder-Munktell in Eskilstuna, whose tractor production Volvo took over in the early 1950s; until 1985 the tractors carried the Volvo BM name, after which Valmet continued production. Designations with the BM prefix and a three-digit number (BM 810, BM 840, BM 860) denote the classic two-cylinder diesels, while models with the Valmet suffix (BM Valmet 605, 705, 805, 905) come from the joint production with the Finnish partner; the KRABAT range and the T models such as T600 and T700 also belong to this transitional period.

The register lists here 27 versions with 22.8 to 122 kW (44.5 to 163 hp), a displacement of 2,240 cm³ in the two-cylinders, unladen weights from 1,650 to 1,860 kg, a length of 2,850 mm and widths from 1,610 to 1,700 mm; the engines are Perkins alongside Volvo's own units.
Volvo BM shaped Scandinavian farm technology for decades, particularly in Sweden and Finland, where the rugged two-cylinder diesels still work on small and medium farms today; the range also marks the transition from the Swedish Volvo BM brand to Finnish Valmet production, from which Valtra later emerged.
On used examples, engine condition and compression, the state of clutch and gearbox, rust on mudguards and bonnet, and the availability of parts, which run through specialist Scandinavian dealers and veteran clubs, all count; on the later BM Valmet models hydraulics and the PTO as well.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
