The Pats’s have pluses and minuses.
I had to learn the hard way not to use the soft bolts that came with it. They will bend and then become unable to remove when you break them off in the casting. First solution was to use a harder grade bolt.
This was mostly effective, then I realized that trying to prevent the Pat’s from swiveling in the lift arm’s ball was counterproductive.
IT NEEDS TO SWIVEL as the implement is raised/lowered. Don’t fight it.
Otherwise, the implement’s pins have to swivel in the Pat’s “hook”, and this leads to a lot of tension and bad things happening.
Also, don’t use those “1/2 washers”. They find a way to slip by the clip. Having a 1000lb mower fall 1/2 off the 3 point hitch when your on the a bad side hill or wedged in a ditch is not fun.
