I like this. A slab sizzor is the same price but unless you have a nearly level surface with good traction you have to move to an Rough Terrain Sizzor and they cost a boat load. This is a great balance, you can get it places only a rough terrai unit could go and the tractor is an awesome balance for stability.
Is it meant to be used while attached to the 3pt, or moved into position, and then dropped off the quick hitch and leveled?
Haven't looked at what the manufacturer recommends.
The 3PH lower arms have to move in unison? They dont otherwise tilt cylinders would not work.
That is not correct, see my post # 32. Either of my 3 pt. links can be lifted 4-5" with the 3 pt. at rest. They are designed to lift so if you hit something when running a brush cutter, other mower or ground engaging implement the implement can raise up to clear the obstruction.
