Volvo BM 2650, 2654

The recent transformation of large tractors means a major improvement of the driver's position. A new in-house-manufactured cab with integral climate control system was developed. The outside air was drawn into the cab at the edge of the roof, where the air is normally cleanest. It then passed through large paper filters before being drawn through the unit for heating or cooling. The large cab was especially appreciated by tractor drivers at machine stations, since there was plenty of space on the floor for a coolbox containing food. The cab had excellent noise damping and insulation and was mounted on rubber mountings, all with the aim of achieving a good driver environment. The floor was flat, the pedals were suspended, levers and controls were located on panels on the sides. The seat was adjustable, with soft upholstery and had folding armrests. Instruments and indicator lights were grouped in a large combination instrument with central warning. Several electrical functions were operated with a combined control under the adjustable steering wheel. A 1260 W alternator and dual halogen work lights made the machine well suited for working in the most difficult of weather conditions.

The engine was a six-cylinder turbocharged diesel engine with an electric heating flange as the cold-start arrangement. Air cleaning was by means of a dry-type air cleaner with paper filter and blocking filter.

Dust was evacuated via the exhaust system, which was fitted with a spark arrester. Large fuel tanks, 210 liters, meant that the tractor could work all day without refuelling. The gearbox was mechanical, with 4 x 2 speeds, eight speeds in all, with the highest gear barred in 30 km/h markets such as Sweden. Usually the tractors came with a fast gear as standard, giving 14 speeds in all. The fast gear was operated electro-hydraulically, with a rocker switch under the gear lever knob. For even easier operation, the power take-off clutch for the independent and driving-wheel-dependent two-journal power take-off was electro-hydraulically operated, as well as the differential lock on the four-wheel-drive 2654. The front-wheel drive was also engaged and disengaged in this way. The brakes were servo assisted (vacuum servo and hydraulics), dry, outboard calliper-type disc brakes.

With the decline in the profitability of agricultural tractors, the 2654 was the last Volvo BM model to be made at the Eskilstuna factory.

There were export models of the 2650 and 2654 for non-European markets. This was available with only a driver platform instead of a cab.
