Just lost a front wheel off the MMM... again.
I suspect the sandy fill soil all around my house (and along our dirt road) is the culprit. Looks like the snap ring that secures the washer, and then the swiveling front wheel, had just worn itself down to the point that it wouldn't hold up under lateral/diagonal stress.
After spotting the snap ring and washer in the grass (Is this a good time for "OMG" or "WTF???" !!!) at the edge of my "lawn" (really, the edge of the woods), I spent 20 minutes looking and finally found the wheel about 12' into the woods --a downslope-- and retrieved it. Yep, it got hit by the blades a few times....
Whew! I just replaced the really worn-down rear tires/wheels, at considerable expense. (Gotta love those M-F prices!)
Hopefully, a pair of new snap rings will cure the problem. Looks like a 1" OD shaft, with a 0.9" ID on the snap ring. Hope I can find that locally. There really ain't much meat left on those snap rings... shouldda picked up on that a while ago, I guess; looking at it now, it's obvious they've been worn down quite a bit.
Live & learn.
