I appreciate all the insights.
I believe TractorLarry was right - the rear differential was locked. I lubricated the diff-lock linkage (at least the portion I can see) and haven't seen the problem since. Hopefully the problem is/was either something in the linkage or my inadvertantly resting my foot on the diff-lock pedal. I'll keep everyone posted.
I also echo your comments on the cub cadet tires - they sure don't look as substantial as tires on some of the other sub-cuts. That being said, they kind of look like the LSW or Galaxy style tires you see used on golf courses to minimize the impact on the turf.
