Diff issue or too long since I've plowed?

[pcustoms]

I have seen plenty of issues with the CK diff locks and bent linkage. Maybe it is time for some re-engineering?

It sure looked odd when I looked up there, definitely not an efficient design with that offset.

Looking at my pic now it appears a little tweaked on the ends

Looks like I can call this one "been a while since I've plowed".

Slightly above freezing today so went out and started the tractor, while it was warming up I marked the LR rim/tire and hoses down the linkages with PB blaster.

Put in in 2wd and tried to push a snowbank back and immediately LR spun. Went to reverse, RR spun. Tried the diff lock (still too stiff IMHO) and got them both to spin. Was trying to come slightly uphill so I expected to slip

Engaged 4wd and backed out. The diff look is not smooth, but it never had been. I'm assuming the bend is factory, but damn this looks goofy:

From another thread:

As said, it's not something that stays engaged, if that's what you mean..? Foot pedal should be in the 'Up' position when disengaged. Otherwise some rocking should let it slip in. The actual foot lever is just a simple lever arm and pushrod setup so not much to go wrong unless its a misadjustment inside the diff.

From another thread:

That looks much better. Be sure to spray a bunch of penetrating fluid where the diff lock pivot shaft goes into the case.

Send both pics to your dealer

From another thread:

Ya, that linkage is definitely bent. As is the tab on the foot lever. You can bend it back into shape but it also can't hurt to ask the dealer for a new one.

Question is though, why did it bend?

Yep, when I first look at the other pic I thought it was a different tractor, but now I see the 4wd linkage. Image looks reverse for some reason, but shows mine is bent

Question is though, why did it bend?

I Can vaguely remember having an issue getting it engaged so I put some weight on it. I'm guessing it was stuck and I bent it.

Need to look at some PN and then reach out to dealer.

Almost looks like something round went in there just past the 2nd 'bend angle'. Large stick/branch maybe..?

Boy, I feel like I'd remember that...

Searching MIE for the closest tractor, looks like this is the part:

No kidding.

This was never in question

My diff lock stays engaged until I reverse. Which is what they taught us in the FFA Tractor Operator class fifty years ago. Never seen one which required constant down pressure. But there are a lot of manufacturers stuff I've never operated, or even seen.
