I bought my TSC PHD a few years back. It's a Speeco. I have a 12" and a 6" auger. My Kubota B7610 has 18 HP to the PTO. Digs with no problems at all. Keep a few shear bolts on hand if you have rocks like we do here in New England. :laughing: I've done more 12" holes than anything else. Sonotubes are fun now!:thumbsup:
