I have to do that with the hydraulic auger we hang off the bucket of the 4020, even while running it in reverse. Especially with the 3 inch bit in the springtime. I've had a back wheel off the ground trying to pull that stupid little thing out of the ground. The smaller bit seems to push dirt aside instead of bringing it out, to the point that it wedges itself in. The larger bit isn't as bad.
The one we have is a Rhino, same gearbox as a 3 pt unit, but has a spacer and hydraulic motor bolted onto it.
