I tried the Harbor Freight type and it won't work with my bush hog or mower.
I bought the Pat's Easy Change and am pretty happy with it. Be aware that Pat's Easy Change will extend the length of your lower 3ph arms which changed the geometry of the 3ph.
I have the C&C TopNTilt (which is great) but with the top link (ram) at full extension it does not push the top of the implement as far backward as I need it to. I discovered that when I could not tilt my box blade as far backward as I wanted to. I was only on the tractor for a few minutes after I found that so I haven't had time to see if there is a way to correct the alignment.
I may have to see about a longer ram for the top link as a last resort.
I still have the Harbor Freight quick hitch and if anyone wants to drive to Jasper, Texas and pick it up I will give it to them for free to get it out of my garage. Sorry, I won't ship it under any circumstances. If you want it PM me.
