Hey there- every once in a while I need a stump grinder for smaller size stumps- I love the 9 or 13hp stump machines from praxis- they rent them at home depot. I want to buy one and only need it for stumps maybe 16" dia max. Anything bigger is for large machines. The small ones are good for manuevring, back yards, tight spots, etc. So the ? is anyone use one? Is it powerful enough? That's my only concern. The 6hp honda looks good to me, but I'm not sure. I want to buy at this point- not rent, but I don'd want to spend $3500 if I can get away with around $2200 and the smaller unit would be easier to transport and store.
