This is a Kwik way loader sold by Sears made for what ever tractor. this came on a model 100 when I bought it. I made a new subframe and mounted it on a 149. So any loader will fit almost any tractor as long as the width is ok. As for HP needed I think a 1811 is just fine. The power is more then enough. I think the lowest is a 12 HP tractor. I only use half throttle on the 149 because your find out that traction will be a problem and not the engine.
Be careful with the aluminum rear end not too strong!!!!!!!!!!!!
