Introduced at just the right time, when tractors were spreading fast after the war, the Volvo T 21 quickly became a popular machine on small farms. Its high ground clearance meant that it was especially well suited for crops planted in rows.
The Volvo T 21 was the base model of the 20-series. Altogether 1 800 of them were produced during 1946-1948. From the gearbox and backwards, the T 21 was the same as the BM 10. It had the same 5-speed gearbox, the same tires and the same enclosed steering brakes and final gears.
It was followed by the T 22 and the T 23, the latter of which was petrol-driven variant with a slightly higher engine output. 1952 saw the introduction of the T 24/T 25, heavier machines with slightly larger engines and bigger tires. A hydraulic lift and a power take-off were standard on these models.
Almost 30 000 units of the 20-series were produced during 1946-1959 and it became a highly popular tractor. A well-known slogan was "no one knows how old a Volvo can become".
