Matt,
The pump mount on my loader is fabricated from an old mule drive.
The QA bolts on the sides of the frame are not used in my set-up.
The rear of the subframe cradles the axle housing from the bottom and clamps over the top hold it on.
I currently have 10.50 tires filled with fluid, 200# of JD weights, 100# of suitcase weights, and 1 set of IH weights on my loader.....or 425-450#
My loader works great, I'm very please with it, however, it will soon be getting some modifications. Later this year, it goes on a stretched frame (lengthened 5" like a Super, but it's a 149....Travis's frame) and gets the following upgrades:
982 front axle
2000# trailer hubs
power steering
5ea. 42# MTD weights
26" rear rubber
7.50 x 16 front rubber
foot drive hydro
red frame similar to Steve H.'s 128
Can't wait to use it after the "improvements", because it's fun to use now!!!!
Good luck with yours and let me know if you need anything else.
