About the Belarus 420A

Production of the Belarus 420A Tractor started in 1983 and continued until 1997. The Belarus 420A Tractor first came out at a price of $14,500 (1997), but you might be one of the lucky ones who found a good deal lower than that. The bad news is that, like any other tractor, the Belarus 420A Tractor needs spare parts to keep it running; the good news is that we have all the parts you need at 60% off dealer prices in our inventory. Sometimes, the parts compatibility is determined by the serial number of your Belarus 420A Tractor, and that info should be listed on the part fit notes. The serial number starts from 273449 for a 1983 model, from 276391 for a 1984 model, from 304013 for a 1985 model, from 327204 for a 1986 model, from 357102 for a 1987 model, from 389751 for a 1988 model, from 400329 for a 1989 model. They also have differential mechanical dry band brakes. The type II 3-point hitch is very reliable, capable to lift 2,630 lbs [1192 kg]. It is also worth noting that the independent rear PTO runs at 540 rpms. The Belarus 420A has an open hydraulics system with a 4.1 gal [15.5 L] capacity. The pump does the job pushing 11.9 gpm [45.0 lpm] fluids in the hydraulics system.
