The unit is described as a 3-point PTO powered stump root grinder for 15-45HP tractors and aims to convert stubborn stumps and roots into sawdust efficiently.

Key Features
From the Manufacturer (About this item)
- Connect: This attachment is powered by the included PTO drive shaft. 540 RPM PTO input, 1200 N·m max. torque, allows for efficient power transfer. Adopting a 3 point hitch for easy installation. It is recommended for 15-45HP Cat 1 tractors and loaders.
- Design: The 24" diameter flywheel is fitted with 34 tungsten carbide cutting teeths. Easily remove roots up to 6 feet below ground level, ready for grading or sodding. A black small box is equipped above the grinder, which can hold instructions, drawings, or various small tools, etc.
- Application: Transforming the roots of various trees into decorative sawdust or coverings. Use for forestry, gardens, park, orchard or plantation. Suitable for carpentry, homeowners, woodworkers or farmer. Designed to work on tractors with a PTO shaft. The stump grinder works best on tractors featuring PTO shafts that are independent of the tractor’s transmission drive system so the operator can control tractor speed independently of PTO.
Detailed Description
The SG24 stump grinder attachment is engineered as a heavy duty PTO root grinder attachment for compact tractors. With a 24 inch flywheel stump grinder SG24 configuration and 34 carbide teeth, it’s optimized for aggressive cutting and longevity. The carbide tooth stump cutter for 6 inch depth is designed to cut down stumps and grind roots at a recommended 6" cutting depth per pass, but the robust flywheel and tooth arrangement allow for progressive removal of larger material. Because it is PTO-driven, the SG24 delivers consistent rotational power (540 RPM input) and up to 1200 N·m torque via the included PTO drive shaft. The three-point hitch attachment makes mounting straightforward, and the small on-unit storage box is a thoughtful touch for carrying spare hardware or instructions.
In practical use, the operator controls the tractor pace while the PTO maintains cutter speed — a benefit when you want controlled, repeated passes on tough stumps. If you’re searching for a stump grinder with 34 carbide teeth or a 6 inch cutting depth stump grinder attachment, this model is built with those specifications in mind. The SG24 is available in a green (orange accent) finish and marketed as a heavy duty stump grinder attachment for those who need a durable solution without buying a full-sized standalone stump grinder.
