Buying a used Oliver 1850
Identify the engine and transmission before buying, because service needs and parts differ among diesel, gas, LP, standard gear, Hydra-Power, and 4WD versions. Test the Hydra-Power shifts under load, PTO and hydraulic function, steering, brakes, and clutch; inspect the Perkins diesel for cold-start behavior, coolant condition, and oil leaks. Exact weight and specifications vary by configuration, so confirm them with TractorData.com and serial-number records.
