The Massey Ferguson 1750 tractor requires a high quality, premium grade hydraulic and transmission oil (multigrade SAE20W-30 or 10W-30) with an API classification of GL-4 or better. It must meet or exceed the original equipment manufacturer (OEM) specifications for its hydraulic system. The additive type for this tractor includes anti-wear, anti-rust, anti-foam, and extreme pressure (EP) formulation to reduce friction, extend service life and provide better lubrication. This type of oil should also contain an anti-oxidant and detergent package to keep the system clean and free from deposits. It is recommended that the oil be changed at least every 500 hours or annually. If the tractor is operated in environments of extreme temperature or humidity, the changing frequency should be increased.
