The MAZ-509 was a heavy logging lorry of the Minsk Automobile Plant, built on the MAZ-500 base. It ran from 1966 to 1978, was replaced by the modernised MAZ-509A that lasted until 1990, and was considered good enough to receive the Soviet state quality mark.

History of the MAZ-509
Two versions of the same lorry
The MAZ-509P was built from 1966 to 1969, and the MAZ-509 followed from 1966 to 1978. As on the base lorry, its wheelbase grew to 3,950 mm. Compared with the 509P, the MAZ-509 had a two-plate clutch, different ratios in the transfer case and in the gearbox, a payload 500 kg higher and a front axle with conventional rather than planetary hub reductions.
On the timber run
Early MAZ-509s of 1969 and 1970 had the same front finish as the MAZ-500. The logging lorry worked with two-axle timber trailers, the GKB-9383 or the TMZ-803M. In 1973 the MAZ-509 was awarded the state quality mark of the USSR.
The MAZ-509A
From 1977 the plant built the MAZ-509A, which carried the external features of the updated MAZ-5334 and MAZ-5335 family. It stayed in production until 1990.
Design and features
- Logging body: a timber lorry of the MAZ-500 family with a long wheelbase of 3,950 mm.
- Timber trailers: designed to work with the GKB-9383 or TMZ-803M two-axle trailers.
- Conventional hubs: the MAZ-509 used ordinary front hub reductions instead of the planetary ones of the 509P.
- State quality mark: the lorry received the Soviet quality mark in 1973.
MAZ-509 versions
- MAZ-509P (1966–1969): the first version of the logging lorry.
- MAZ-509 (1966–1978): two-plate clutch, other transmission ratios, 500 kg more payload.
- MAZ-509A (1978–1990): modernised version with the front of the MAZ-5335 family.
The MAZ-509 was part of the MAZ-500 family, and the MAZ-5335 that followed kept a logging version in the MAZ-509A. More are in the MAZ collection.
