There are quite a few brands of PH diggers so I don't know which ones are good or not. I have a woods ph35 which according to my dealer is a more heavy duty one. I added it to the cost of my tractor when I bought my tractor. I probably didn't need this particular one as it's pretty pricey but I figured it could handle a larger tractor when I upgrade.
