John Deere SS30 High-Torque Stump Shredder

Double tap to zoom

Remove stumps from 203 to 711 mm (8 to 28 in.) in diameter in a single pass. Easily remove larger stumps with multiple bores.
Hardened pilot cone draws auger into the stump while 19-mm (0.75 in.)-thick AR500 steel blades efficiently make the cut.
Low-speed, high-torque auger planetary drive shreds material more safely and without the dangerous flying debris of conventional stump grinders.
Bore 508 mm (20 in.) into the ground to remove feeder roots.
Even with slower operating speeds, stump removal is faster than with conventional stump grinders. Site cleanup is easy thanks to the small, contained chip pile.
No carbide tools to replace lowers operating costs, and maintenance required only every 1,000 stumps maximizes uptime.
Like all Worksite Pro™ attachments, this stump shredder is optimized to work with John Deere skid steers and compact track loaders (CTLs). It’s also compatible with most competitive models. See your local Deere dealer for details.
