This document provides the operator's manual for the Massey-Ferguson 50 tractor.
This is the operator's manual for the Massey Ferguson MF 50 gas and diesel tractor. Its contents cover lubrication and maintenance, the break-in procedure, operation (instruments and controls, starting the gas tractor, starting the diesel tractor, Multi-Power transmission, selecting the correct gear, stopping the tractor, attaching and detaching mounted implements, the hydraulic system with Quadramatic controls, position and draft control, the standard drawbar, Power Take-Off and wheel tread widths), servicing of the diesel and gasoline engines and their systems, accessories and specifications. A serial number table lists MF 50 numbers and model years from 1958 (515708) through 1964 (536062), and paint information gives the tractor body color as Industrial Massey Ferguson Yellow.
The copy states on its first page that it is a manual produced by Jensales Inc. without the authorization of Massey Harris Massey Ferguson or its successors, which are not responsible for its quality or accuracy. Practical instructions include locating the tractor serial number plate on the left-hand side of the battery platform, running the engine under normal load at normal operating temperature during the first 25 hours, changing crankcase and transmission oil after the first 50 hours, 200-hour tasks such as replacing the engine oil filter element and cleaning the oil sump screen, and 750-hour tasks such as changing transmission, hydraulic system and differential oil. It also explains adjusting eccentric pin type and ramp type PAVT wheel widths, with ramp nuts tightened to 100-125 ft.-lbs. torque, and liquid-filling the tires for extra traction.

The manual says to change the crankcase oil and the transmission oil after the first 50 hours of operation.
Two types are used: the eccentric pin type, which is used with high clearance tractors, and the ramp type, which is used with standard clearance tractors.
