I take it, since you asked about the 3-point hitch, you don't have an A yet. An A I don't believe had a factory three point hitch. Some A's might have a 3 point hitch that has been added on. An A is pretty small, just a little bigger than a Cub. I don't know what you are planning to use this A for but sounds a little small to me for a loader possibility. I have never run a loader on anything smaller than an H. A loader seems to work better on the M than the H and I believe it does becuase of the bigger sized tractor. An A is really a yard and garden sized tractor even though some people go to the field with them. They just aren't big enough to really go out and get alot done on. Alot of people like the A for gardens and bigger yards and they can put it in a little fart of a shed becuase it don't take up much space. Tell us what you are planning on using this A and loader for. It is hard to say what you need when we don't know what it is going to be doing.
