The 705-4 is a tractor from the Volvo BM Valmet brand, classified within the group of agricultural tractors. This model was produced from 1985 to 1986 and represents a specific variant within the model range of that period. As a four-cylinder tractor with a displacement of 4,390 cm³, the machine is aimed at users requiring a defined power output for typical field operations. The design follows the technical standards of the era and offers a clear layout focused on agricultural use without unnecessary complexity.
The engine power is 61 kW, which is sufficient for handling medium draft loads and driving common implement attachments. With twelve available gears, speed can be adjusted to various soil conditions and working speeds, supporting efficiency in field cultivation. The curb weight of 3,875 kg ensures stable traction, while the gross vehicle weight of 7,412.5 kg defines the maximum load capacity from attachments and ballast. The external dimensions of 4,427.5 mm in length and 2,210 mm in width determine maneuverability in the field and transportability on public roads.
Within the series, the 705-4 is positioned as a model with a clear power assignment. The technical equipment with four cylinders and the specified number of gears forms the basis for its classification. This configuration is suitable for tasks such as plowing, sowing, or transporting harvested goods. The combination of weight and power enables the use of heavy implements, with the chassis dimensioned for the permissible loads. Users find here a machine that fulfills its tasks in the medium power range of the Volvo BM Valmet tractors of that time.
Volvo BM Valmet – other models: the collective page of tractors from the Swedish-Finnish merger years 1979 to 1985, from the 505-4 through the 705 and 805-4 to the 905X4, 50 to 105 kW, three- to six-cylinder diesels
This page gathers the tractors that carried the name Volvo BM Valmet – the joint marketing arrangement Volvo BM of Eskilstuna, Sweden, and Valmet of Finland ran for their tractor programmes from 1979 to 1985, before Volvo gave up its stake in Valmet, from which the independent Valmet Traktor brand emerged. The types carry the familiar logic of both houses: a three-digit number for the power class, the digit after the hyphen for the number of driven axles – the 705 as two-wheel drive, the 705-4 and 805-4 as four-wheel-drive versions, the 805-4-4X4 with an additional four-wheel-drive marking, the 905X4 as the range's top model.

The register lists here 7 versions with 50 to 105 kW from three- to six-cylinders of 3,290 to 6,600 cm³, unladen weights from 3,190 to 4,300 kg, gross weights from 7,412.5 to 10,500 kg, lengths from 4,290 to 4,700 mm and widths from 2,013 to 2,210 mm.
The merger years tied the Swedish Bolinder-Munktell tradition to the Finnish Valmet programme before the two houses went their separate ways again in 1985; the tractors of this transitional period are still in use in Scandinavia and sought by collectors documenting the brief shared model history of the two marques.
On used examples, engine and turbocharger condition count, the condition of the four-wheel drive and front axle gearbox on the -4 versions, hydraulics and PTO, and rust on cab and mudguards; spare parts run through the successor networks of Valtra and Volvo.
