So I put the PHD on the tractor, then took it off and only used the 1 rear hanging point. I disconnect the lift arms 1st on removal, connect them last on install. It was a little harder to take the PHD off at the toplink since there was a bit more lifting involved, and a lot more pull on the pin. It was a little harder still to put the PHD on with more lifting and so forth to get the toplink on. Basically, by the time you wheel it around a bit you have to lift the PHD arm up a few inches, support it, and get it lined up and put the pin in. With the two support points, it was much closer to lined up and less lifting to get the pin in. Pin removal with the 2 support points took near zero force- when you set the PHD down, it all settles to the right spot.
I think the 2nd support is a win, but then I already put in the effort to build it. It is clear that as I get older (which some days seems like it's in about 20 minutes) that I'll like the 2 support system more and more. I understand that it just takes one hand to position everything, it's just when that ugly arthritis starts to set in seems like the one hand can do less and less.
BTW, it's definitely less than 2 min to remove, less than 4 to put on including firing up the tractor to get the lift arms close to the right height :thumbsup:.
Maybee the answer is build your dolly stand so it can take a 2nd set of supports, then if some day you need them you can add them. If you're over 60, just build the two support system.
Just my opinion, YMMV, void where prohibited. I'm through singing now.
