i am new to the tractor world. i have a woods bush hog, tsc box blade and now phd. my tractor is a 71hp kubota. today i dog 30 holes through clay and roots for a new pig pen. the tsc phd work better than expect. it appeared like it would not work at first because it seemed to rest at an angle and i thought i would require another person. the phd digger worked great after all. i recommend it for the price. i paid 394 plus 109 for a 6inch auger.
