Compact Commercial Stump Grinder with Kohler Power
The BlueBird SG13K uses the same compact commercial SG13 chassis with a Kohler engine configuration. A 14-inch cutting wheel, narrow 27-inch width and adjustable operator handle make it well suited to rental fleets, landscapers, tree-care crews and property maintenance where access and portability matter.
- Engine: Kohler CH440
- Power: 13 HP class
- Cutter wheel: 14 in.
- Cut depth: Variable, up to 12 in. below grade
- Frame: Welded 7-gauge steel
- Drive: Double V-belt
- Clutch: Noram centrifugal clutch
- Machine width: 27 in.
- Weight: 345 lb
- Handle: Adjustable to four operating positions
Why the SG13K Stands Out
The SG13K is designed to combine commercial cutting capability with a compact footprint. The chassis can move through narrow access points, while the adjustable handle and clean sight lines help operators control the cutting wheel across the stump.
