I would really hate for you to buy a larger tractor with the primary goal of being able to lift more and then not be able to move it very well. Buyers remorse has the potential to get very expensive.
Yes, that's what I'm trying to avoid, and I thank you for your input. When I was young you never saw a 4wd. My 2wd 504 farmall that I mentioned earlier had a loader. It wasn't like using a modern 4wd but it worked. It also weighed almost twice what a 5640 does.
My biggest fear in this situation is that I buy a 2wd, find out it doesn't work for me, and then not be able to sell it without giving it away. Xring you are correct that most loaders are 4wd. I do have two neighbors with 2wd loaders. But they are BIG HEAVY TRACTORS, and they still run counterweights.
Are you going to keep the tractor you have now?
At this moment yes, at least untill I'm sure about my next move. I don't need nor can I afford two machines. So I'll sell mine or trade it if I find something that works better for me.
I can go up to a
L3940 and keep my 724 loader. Lift cap goes up a little I think the 3940 pressure runs a little higher. But I don't gain much. 7hp more and a little larger tires.
