Hey All -

Wondering if anyone else on here has had troubles with the Mower Deck not locking out to limit movement when using the rear three-point hitch?

Mine just started doing this also :mad: :mad: :mad: :mad: . It worked before( when I bought tractor in winter and took deck off to plow driveway). I know it worked before I dropped off at dealer back in June. I went to lock it up the other day and it stops at the notch before "Top". I know the mmm linkage gets stuck at the top and needs assistance to drop down when mounting the deck....

@dieselbob69 I've looked for grease spots or adjustments screws but there isn't anything. I haven't done anything different over the past few times using it.

If you find out a solution before me please gladly post it.

What works for me is to raise the deck up as far as it will go, then get off the tractor on the left side, grab the edge of the deck and lift it, twisting the height adjustment knob to the lock position at the same time. Unlocking it can be done from the seat.

Ugggh. Trick in above post did not work. Another site, someone recommended adjusting the linkage set bolt( left side, behind wheel) - no dice with that. Took deck off and had a look see. The bottom of that spiral cam has a nub sticking out on 1 side, it looks like it’s supposed to go into that notch that is on the linkage. I ended up grinding the bottom of that spiral flat, and ground some of that nub off with my Dremel I was able to get the knob into the “top” position with deck off. Once I got deck on it wasn’t as nice. I need to grind sone more off that nub, I need to get another stone for the dremel though. I believe I’m on the right path, don’t know why it would work before then not be able to… these pics are after I ground it down....
