135 Tractor
The serial number of a Massey Ferguson 135 tractor can usually be found in one of three places. The first and most obvious is the tractor’s data plate, which is usually located in the operator’s compartment or on the right side of the engine. The second place to look is on the rear of the tractor frame, near the main lift arm. The third place to find the serial number is on the inside of the front axle housing.
