My 44 on the 332 handles just fine with some rear weight. The wheels are filled and a set of double notch weights. I had the tiller on for a while but took it off as it’s just too massive. I have had a 3/4 bucket of dirt in it with no noticeable tippiness, but I keep the bucket low to the ground and the land is flat. I’d image the two extra ponies of the 318 would help a bit on the hills. The 44 is a small bucket with a close center of gravity, well designed. Mine will not lift 500 #’s. If it did I’m sure I’d have rear traction problems with my current setup.
