I have a lowe brand auger on my new holland l775 skid steer, and having trouble making any real progress drilling 18" x 4.5ft deep holes without a helper on standby to scrape clay out of the bit with a shovel.. even with a helper it is VERY slow.. in sandy soil or topsoil it is not a problem. but in clay, even if i wet it down etc the bit gets clogged with clay quickly and i have to get out and scrape the clay out, then can drill another 2-4" before it happens again. the teeth are sharp on the auger bit, and i was told by the shop i got the auger bit from it was a good one for clay & rock. it doesnt seem to matter if i put downforce/weight on the bit, go slow, go fast, etc. temps are in the 50s and the ground is pretty wet, but once you get into the clay layer it is dry. if i pull the auger up out of the hole and spin it fast both ways the clay wont come off. I dont have water hose on site, but can haul buckets of water. any tips or thoughts greatly appreciated.
