I searched stump grinders on here and didn't find much.
Here's my main criteria.
I picked up a used Honda gx390 to try as my first motor. If it doesn't cut it I might upgrade to one of those 27 hp predator engines or some other v-twin.
The cutter head is going to be made from a 9.5 inch diameter steel circle, over all cutter head diameter will be about 12 to 13 inches. Probably use taper lock weld on flange and pulleys on the cutter head.
Cutters will be eight, 700 series green teeth.
New stump grinders are stupid expensive, used ones I find are beat all to hell and priced almost as if they are new.
Rentals are $300 for half a day and they are all junk and look like $700 to $1,000 cheapies, basically glorified lawn edgers. You would need to rent it half the day to grind away a single 3 foot stump.
I'm building about a $2,500 to $3,000 price point one.
Anyone know of 1 inch heavy duty pillow blocks that have a really good seal?
