I have a JD 444, a 1978 model. I thought it was a 100hp. (Triangle Bar, I think yours should be higher than mine.) We bought it back in '92 to move some dirt & manure, but mostly to carry 2 bales to save on the front end of our other tractor. We fed with it for about 8 years, but it isn't fast enough, only carries two bales and lacks the comfort of newer models. We really are not in a feed yard situation. It has a 1 3/4 yard bucket. It will unload the top bale off a hay trailer. Have bent some hay racks on the taller trailers try to reach all the way across and take of the bale on the other side. On stacks of round bales on the ground, stacked 3 high, it is difficult to grab the top bale from the side, you almost have to take it off the end of the stack. I still really like the tractor for loader work and use it for the hardest worked. You would have to be pretty hard on things to hurt that loader. But have upgraded other tractors to carry 2 bales on bucket and either 1 on 3pt or carry gooseneck on 3pt.
I bought a grapple for a Case-IH loader, dual cylinder and mounted on it. It is tough enough but should have a little more reach on it as the teeth don't quite reach down to meet the bucket, especially for grabbing small things or loose hay or chopped hay.
