Sounds like you want my tractor! I have similar needs and equipment aspirations, and this spring I bought a
L5740 with two rear remotes and the 3rd function on the loader. I am using my remotes for top and tilt cylinders, and the third function is ear marked for a grapple that I hope to order soon. I love the tractor and it has exceeded my expectations. I am very happy with my choice in hydraulic options too. I was on the fence about the extra cost but I am so glad I found a way to make it happen. If I did need a third rear remote in the future it could be easily added as the framework is already there to accept it. I don't anticipate having to do that though. I have a lot of options with my setup. The top and tilt has been fantastic with my box blade. It makes grading work a breeze. I went with one float detent valve and one standard return which has been a great pairing.
