Posi - Lock on a BX2230

[Junkman]

You should be stopped when shifting the diff lock into place, but once in place, you should see both wheels spinning in the above test. If only one spins, then it isn't engaged. That is what he is saying. Many times, I have thought that it was engaged, only to find that it wasn't. I looked under the floor board and was surprised to see the reason that the diff lock is so "spongy". It uses a flat piece of steel as a "spring" when you push it down. Guess that is so it will not be forced into position unless everything lines up. I have had it "grab" with my foot on the lock and I am just starting to move the hydro pedal. I don't find that I need it very often, as the 4 wheel drive is usually enough to get me out of anything that I get into. I avoid getting into mud holes with my tractor as some have pictured on the forums. Caution, like experience comes with age... /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Junk beat me to it. The spring steel bar prevents you from putting excess pressure on the Diff lock pins when they are not engaged.

I've only used it during the winter when getting the tractor stuck in the snow. You know when it's in because turning the tractor is impossible almost.
When you depress on the pedal and it engages it actually pulls the pedal a little lower towards the floorboard. You can feel this when it happens.
