The size of the plow recommended for a Massey Ferguson 240 depends on the tractor’s intended purpose. Generally, tractors this size are used for smaller acreage, smaller gardens and hobby farming. The size of plow recommended would depend on how much land you will be working with. A general recommendation is a 3 to 4-bottom plow for most small acreage. This plow size will provide enough depth and width to suit your needs. If you are looking for something larger, a larger 4 to 6-bottom plow will be more appropriate.
