Could not recommend it enough. This post hole digger has paid for itself the first time I used it. Had it little ove a month now and from the time you put it together you can tell that it’s built heavier than most of the ones out there. The fact that this is one of the few units that allows you to mount a hydraulic downpressure cylinder also speaks of the build quality. There is a reson why the box store ones do not offer that, the boom would split in half the first time you operated the cylinder. In my opinion if you live in an area with hard clay, the hydraulic downforce kit is a must have.

Extremely sturdy unit. A word of advice, get the stand and a few extra points as they wear fast on clay soil like mine.
