Looking back at the previous comments makes me wish I had just a bit more cash to have built my stump grinder differently. May be one day, hope soon.
My theory with the open handles was to be able to get my body in there to help move the grinder, take some of the stress off the arms and shoulders. I've been posting how long my grindings have taken, not sure if it matches up with anyone else running a similar setup. I know the rental units I've used took 3 times longer.
