It had to happen eventually. I was out moving some old stumps from a pile on my property to the back fence line saturday with my David Brown 880e and loader. I just finished up putting power steering on it and wanted to give it a workout. So I had maybe a 600 pound stump on the loader and went through an area where the neighbor used to have a large tub grinder to make mulch. I buried my tractor in about 2 feet of rotting mulch. I ended up taking the stump off the loader, rocking it back and forth and using the differential lock to get it out. I should probably have more weight on the back.
