I have both. But have never used my QA. But I will say, I'm not sure the 1450 can handle the 450. I have a 450 on an 1811, and I am telling you.... IT'S ALL THAT TRACTOR WANTS in heavy snow. I don't think you would be happy with the 450 on a 14HP tractor. IF you can even make it work. This is one attachment that NEEDS a 5/8" belt. I have slipped the belt on mine before, I DO NOT think a 1/2" belt will hold it. I suggest you stick to the QA.
