While they may be the best thing since sliced bread, I cant see the value of spending almost $200 to add Pats when you have the sliding extensions already. If you cant get your tractor's lift arm ball within 3" of the implement, you don't belong in the drivers seat.
Pretty harsh for a Sunday. A smiley icon at the end might have been appropriate.
Anyway, often the implement is not level with the tractor. If you don't have a T&T then the Pat's will hook up one side and then a little more lift will hook the other side. Extendable arms do not have this feature and will lead to wrangling with the vertical lift arms until things are lined up.
The lower arms have to be spread wide enough to go over the lift pins. That means there will be slop in the implement until the check system is tightened (for an implement that is wanted tight). With Pat's that adjustment is already made from the last time.
If your last implement was tight then the check system has to be loosened to get the lower arms disconnected from the pins. With Pat's a lever is lifted and the arms lowered to clear underneath.
The balls are often hard to slide on the pins and need lubed. Another trip to the barn for WD-40. Not so with the Pat's.
The lower arms can be hooked up from the seat with no further effort. Yes, the top link has to be hooked up from the ground.
Is this all worth $200? It is an opinion. An opinion that should be made after actually using the Pat's system. Of course, then it is too late because the commitment has been made. Some extenuating factors include age, disabilities, back condition, patience, ADD, ADHD, and there are probably others.
