Yeah, it is not easy. I have years of practice with simple one-gear-pump systems: first my homebuilt CADDigger 728, then my backhoe attachments on my tractors. These are much harder to use, vs. fancy modern hydraulics, with load-sensing and multiple HST-type pumps.
I use loader float all the time with 4n1 bucket, but rarely with a conventional bucket. When going forward in float, the tractor front end tends to come up when you push all but the lightest of materials. I can see using it pushing snow, but only powder, and not much at that.
