I tried putting the bucket down on edge. It lifted the tractor fine. I just wasn't paying any attention to the physics of the loader. The loader cylinders are fully retracted at ground level. Don't remember the 2305 loader doing that.I do not have a post hole digger (except manual ones) but I've seen a couple youtube videos.
Seems common for auger to screw into ground and not want to come back up. Soil type and auger tip design contribute to that. Some guys say they put less aggressive tips on and it worked better.
My 1025r loader and bucket will easily lift the front end, no hesitation there at all. It is a 2022 with the 120R.
I tried removing the tip, but it would not go down at all. I may look for a less agressivee tip. The one that comes with it is a 6" screw.
