How does this look?
Here's a thread where I started out asking questions the same as this thread, and my design evolved to the photo above.
Photo below was during construction:
A full-width toolbar rests in the hooks of the qhitch. This toolbar has chains going forward from its outer ends to the drawbar socket on the tractor. Designed so if (when!) I snag a tree in the orchard I will just stall instead of bending the toolbar.
Behind the toolbar, four chains going back to the mount points on the spike harrow.
Lift: A pulley at the top of a mast that was salvaged from junked exercise equipment. A wire rope goes from the back of the spike harrow up over this pulley and down to the tractor's drawbar socket. Raising the 3-point with the tractor end of this cable fixed low on the tractor, gives a compound lift to the spike harrow.
Everything to lift and pull the harrow was built out of scrap on hand. The pipe got welded to the little boxes on the angle-iron 'toolbar' plus I added plates adjacent to the qhitch's hooks. Three season's use now and I haven't bent anything.
One advantage of this design over a ginpole lift is: Raising the 3-point pulls the harrow in snug to the toolbar so it doesn't sway and makes the overall rig a little shorter, which helps when making a tight turn near the fence.
