No luck yet. I had only a couple of minutes. I started the tractor, put the hydraulic lift setting for MMM on lowest setting (confirmed by the ballast box on back going to lowest level). Turned off tractor. Still could not pull arms of lift frame assembly down to level of mower to link it. Any ideas? Does the engine need to be on when I lower the lift arms manually?The grass is growing!

Mike, I will go out and check mine when the rain stops and post the results.

Assuming you are certain there is room for the arms to drop, take a wrench, or whatever works, and gently pry the arms down, with the hitch dropped. They should drop fairly easy.
I had the same problem about the first 10 times I tried to re-attach the deck. For whatever reason something was a little tight. Eventually the arms loosened up. Be sure you keep them lubed well. I believe one time I could not get the arms down and tapping on the lift rod (@ the hitch) with a mallet and block of wood did the trick. Think I had to remove the stop on the back of the rod, IIRC.

I just checked my 2450 and the three point arms would go down with the engine off. I just took the lever for the deck/3 point and lowered it and then pushed straight down on the upper arms and they moved down, no problem. When it was newer I remember having to put my 250#+ on it to get them to move.

Gods Country and Marauderer-- you both got it right. I couldn't pull the hitch arms down by hand, but with a crow bar on top of one hitch arm I gave a couple of good whacks to the crow bar with a hammer and the arms came right down. I appreciate your help. have a great weekend!

Be sure to check the Sub Frame Lock Out (page 17 in MMM manual). This two position , spring loaded bracket is used to isolate the underbody mid mount brackets from moving when the 3 point is in use. I lock mine out whenever the mower is off so I wont snag the lift arms on any brush etc. Good Luck:)
