I purchased a TC40DA last spring, moving from a '64 Ford 4000. A also have Cub Lo-Boy and I mow about 5 acres, have 10 in native grass (bush hog some years) and plow about 2 acres for food plot/fire break. I ordered a loader, backhoe, one set of remotes and seat arms. The remotes are for my 3pt splitter. I also have a zero-turn mower for the 5 acres
I love the hydro, especially for bush hog work. My old Fords (I had an 8N at one time) didn't have enough gears to match PTO and ground speeds. It is perfect for loader work too. It worked great for plowing. The only issue I had was using it with a spreader. I needed a speedometer - and I'm working on adding one right now. I would drive a hydro around the lot. It does take some getting used to, but I sure wouldn't go back to gears.
If you don't get the "deluxe" model, spring for the seat and the extending 3pt arms that are part of the hydro package. I enjoy the arm rest on long mowing jobs.
Jim is right about the 3pt arm adjustment. It is a pain and I'll add TnT some day. If you can swing for all three remotes, I would do that.
My dealer doesn't like loaded tires. He gave me rear weights for half off. You can read the pros/cons elsewhere, but the weights have worked well. He also added a block heater, which you will need.
This is a great tractor. I'll be happy to talk about it all day. /forums/images/graemlins/grin.gif
