Congratulations on your new tractor!

A 3pt can be put on these without much trouble. You'll be a LOT happier with it if you get one that lets you keep the original drawbar. Mine doesn't, and I miss it a lot!

Controlling a 3pt with the liftall is not impossible, just not as easy as with 2-way live hydraulics. There are different ways to do it, depending on what kind of hitch you have, and where the cylinders are located.

One possibility is to use a "depth control" cylinder on it. These used to be common on trailing plows with hydraulic lift. They have a collar which is fastened around the cylinder rod and is adjustable. When the stroke reaches a certain point, the collar pushes a valve control rod inside the cylinder that shuts off the oil, stopping the cylinder. This works especially well on the hitches that have the cylinders mounted over the rear axles and lift when closing (retracting) the cylinders.

If the cylinders are behind the rear axle, and lift when extending, put some "snap-ring" collars around the cylinder rod to stop the retraction at whatever level you wish. These are available at farm-supply stores for very little cash.

I took a different approach on my 3pt, as it wasn't set up the way I wanted it in lots of ways. I moved the cylinder out from behind the axle and positioned it over the left rear axle so it lifts by retracting. I also increased the size to a 4"x8" cylinder, and it lifts all I want to hang on the hitch. Where the cylinder used to be (down under the mechanism and behind the axle) I put an adjustable stop consisting of two pieces of telescoping pipe with a series of holes in them. I put a pin through the holes I want to regulate the lowest point the hitch will drop to.

You'll find that by pusing the hydraulic control rod forward VERY CAREFULLY you can lower the hitch slowly. It's NOT an "all-or-nothing" quick release if the pump control valve is in good shape. If you can't get to hitch to drop slowly with a heavy load, put an adjustable flow contol valve in the hydraulic line. These are available with free flow in one direction, and restriction in the other.
