Last weekend I rented a 13 horse stump grinder. It was $175 to have it from Saturday afternoon until Monday morning. Yesterday was Thursday, and I'm finally getting over the soreness from using it. I could definitely find a use for that stump grinder several times a year, but they would be small 1 hour jobs. Loading and unloading that grinder is also a two person job.
I priced a new stump grinder, and they start around $2000. I saw one that had a horizontal grinding wheel, and was powered by a 6.5 horse motor. It made me think that I could build my own. I've got a "Swisher" brand brush cutter. It's sort of like a cross between a lawn mower and a weed eater. It has a 5 horse lawn mower engine that turns a big weed eater type of head ahead of the motor. (It sort of looks like an aardvark). There is a v-belt that connects the crankshaft pulley to the pulley that turns the weedeater head. I thought about removing the weed eater head and replacing it with a metal disk adapted for stump grinding, complete with grinding teeth.
Do you think this idea would work, and do you have any suggestions?
