Making Stump Grinder 15hp

I built a machine for grinding / milling stump. I made a 350mm disc, and to drive the shield used gas power engine 420cc 15HP. I reduced the rotation on the disc. I reduced the rotation on the disk with teeth by using 120mm pulleys on the disc, 80mm pulley for the engine. In order for the machine to be safe, I made covers of thick sheets, brakes and an emergency switch that immediately turns off the machine. The machine does a great job, the disk rotation is not too high or too low, easy to maneuver even in difficult terrain. --------------------------------------------------------------------------------------------------------------------------- Music by YouTube library amzoid - Princess Audio Hertz - Finally The Sun Patrick Patrikios - Cruise With Me An Jone - Modern Time Rachel K Collier - Beatles Unite JVNA - Demon An Jone - Time to Spare Verified Picasso
