Robert, on the TC40, if you disconnect the loader, you could use the loader remotes and the joystick for control, but the quick disconnects are in front of the driver's right knee, so they are unhandy for any rear attachment, even if you remove the loader. There are standard remote blocks, each with a separate dual-acting control which mount to the rear axle casing just on the right-hand side just above where the 3 ph lift arms exit. You can add one, two, or three. The first one is about $300 and the remaining two are about $175 each, or all three for around $600 if you install them all at once. I think the smart thing to do is to get all of them when you buy the tractor so you can negotiate the best price. I got only one and I wish I had the other two.
