The 3 digit model FX tractors are newer models. I don't know any details about them though.

Actually the model number reflects the PTO horsepower, YM1500, 15 pto hp, YM3110, 31 pto hp. Most people add 3 hp to the smaller models for the actual engine hp, YM1500, 18 engine hp and they usually add about 4 for the larger models like a 2620 or a 3110.
