Tractor
The type of hydraulic oil that should be used in a 1955 Massey Ferguson 35 tractor is specified in the owner’s manual. Generally, a multi-grade oil, such as 10W-30, should be used in order to ensure adequate lubrication throughout the range of operating temperatures. For the specific type and viscosity of oil recommended by the Massey Ferguson company, please refer to the tractor’s owner’s manual.
