3 point and deck
 

I finally got to install the 3 point that I bought a couple months ago on my 125. Installation went OK, but I have a problem. When I went to put the mower back on, I found that the mower undercarriage won't go on with the three point installed. The lift bar attaching plate interferes with the arm from the undercarriage that goes to the rock shaft. Is this normal? Did I install something wrong? How do I get around this? I can't imagine that I would have to take the plate on and off. I attached some pictures that I hope will make more sense than what I have written here.

Your mule drive undercarriage goes on the inside of the lift arm.There is a wear mark on the the foot rest support from that arm.Your arm goes on there.

Well, that looks pretty obvious when you add the arrow! I'm not sure why I couldn't get it to go there yesterday, but I'll go back out to the barn and mess with it some more. I was hoping that it was something stupid that I was doing wrong.

That made me feel pretty stupid! For some reason, the arm from the carriage wanted to be in that slot. With a pipe clamp, I was able to bend the arm enough so that it would land clear of the ratchet and plate.
Thanks for setting me straight.
