Hey guys, for those of you talking about the pain of switching attachments...have you looked into something like this? I think it's about $170, but looks to save quite a bit of time.
I've been using the Pat's Easy Hitches for a number of years. The last set I bought about two years ago was probably about $50 less than you show. They are great. For most implements, it is just drop it off, and back up to the next one and pick it up. I love the things.
Unfortunately, they still don't make hooking up a PTO any easier. That still remains a 10-bad-word experience.
