I have a M5040 and got it stuck last night and was unable to extract it in 4x4. The front tires were spinning and digging in deeper, but the rear wheels were not pulling or spinning as I thought they should. The mud under the bucket was too deep and soft to be able to use bucket to lift an push back. A second tractor solved the problem, but I wonder if I missed an option to use tractor features to do the job alone?
