MechMaxx SG24 34-Tooth PTO Stump Grinder (15-45HP)
The MechMaxx SG24 is a 3-point hitch stump grinder designed for tractors in the 15-45 HP range. It features a 24″ flywheel fitted with 34 tungsten carbide cutting teeth, enabling efficient removal of roots up to 6 feet below ground level. The PTO drive shaft delivers 540 RPM input with up to 1200 N·m torque for solid power transfer. A compact black tool box sits above the grinder for storing manuals or small tools, aiding field maintenance. This model is well-suited for forestry work, gardens, parks, orchards, and farm setups where quick, dependable stump removal is needed.
Key considerations include compatibility (Cat 1 three-point hitch) and depth capability. Its 6″ cutting depth allows substantial clearance with fewer passes, and the design supports easy transport and operation on standard tractors. The SG24 is favored for projects requiring reliable, heavy-duty performance with a straightforward setup.
MechMaxx SG24 Green 34-Tooth PTO Stump Grinder (15-45HP)
This is a green variant of the same SG24 design, offering identical power, cutting depth, and tooth configuration—34 carbide teeth on a 24″ flywheel. Powered by a PTO drive shaft with 540 RPM input and up to 1200 N·m torque, it maintains efficient power transfer through a Cat 1 three-point hitch. The model supports roots removal down to 6 feet below ground level, facilitating grading or sodding after stump removal. The included storage box remains a useful feature for field tools and quick-reference materials.
Operators should verify tractor compatibility and ensure proper ballast and safety measures during operation. The mechanical simplicity of the SG24 Green makes it a reliable option for homeowners, farmers, and professional users seeking predictable stump grinding with minimal downtime.
MechMaxx TSG61 Hydraulic 3-Point Stump Grinder (35-60HP)
The MechMaxx TSG61 uses dual hydraulic cylinders to position the milling head, allowing adjustments from within the tractor cab. It employs a 24″ cutting wheel with 16 carbide teeth designed for demanding field conditions. The grinder provides a cutting depth of 18 inches above ground and 12 inches below, enabling it to tackle tougher roots and varying stump sizes. This hydraulic approach offers smoother control, precise adjustments, and faster responses when working on challenging sites. It suits larger tractors in the 35-60 HP range, including forestry, orchard, and large-scale landscape projects.
Considerations include hydraulic system compatibility, control ergonomics from the cab, and maintenance access. With robust teeth and deep cutting capacity, the TSG61 balances power with operator comfort, making it a strong option for professional crews and larger property management tasks.
MechMaxx SG380 Gas Power Stump Grinder (15-60HP)
The SG380 is a gasoline-powered stump grinder featuring a 420cc, 15 HP engine with electric start for quicker starts and easier operation. The 12V 20Ah battery supports an electric start, and a tow bar system facilitates on-field transport. It uses 12 carbide teeth on a 14″ cutter wheel, delivering a 15″ cutting height and 10″ cutting depth, enabling efficient stump removal on medium to larger stumps. Kevlar belts improve wear resistance, reducing maintenance frequency. The machine’s 65-degree swinging chassis accommodates stumps up to 31.5 inches in diameter, while safety features and a sturdy design help manage worksite risks.
Key considerations for the SG380 include engine maintenance, fuel availability, and weight distribution during transport and operation. While heavier than PTO models, its off-grid mobility and quick-start capability suit users needing rapid, self-contained stump grinding on farms, properties, or job sites without readily available tractors).
10 Pack Stump Grinder Teeth, 2-7/8″ Long, 3/4″ Width
This batch includes ten teeth with compatible specs for common grinder models. Teeth are carbide tipped, offering extended wear life and consistent performance. It is important to verify the compatibility with specific stump grinders such as Baumalight 1P24, Ashland FS19, Shaver SC50, JCB, Bradco SG26/SG30, and similar units. The pack note highlights that some models, especially woods stump grinders or woodland mills, may not be compatible, so cross-checking the exact jaw geometry and mounting nut sizes is essential before purchase.
Vermeer SC252 Green Teeth Set (16)
Genuine OEM Vermeer teeth for the SC252 series enable straightforward replacement or rotation to reveal fresh cutting surfaces. The set of 16 teeth is designed for quick changes, saving downtime and ensuring consistent grinding performance. The ability to replace worn teeth rather than entire sets helps manage maintenance costs over time, particularly for commercial operators with frequent stump grinding tasks.
Barreto SG30 Green Teeth Set (16)
Barreto SG30 Green Teeth comprise a 16-piece set of genuine OEM teeth designed for quick replacement and easy turning to expose new cutting surfaces. This helps extend the life of the grinder’s cutting wheel and maintain efficient stump removal across various stump sizes and species. The set is positioned as a cost-effective maintenance option for owners of mid-range stump grinders.
Buying Guide: Key Purchase Considerations
- Tractor compatibility: Verify horsepower range, hitch type (Cat 1 vs Cat 2), and PTO or hydraulic inputs. Some models require 540 RPM PTO, while others use hydraulic control from the cab.
- Cutting depth and wheel diameter: Deeper cuts speed up grinding but may increase wear and require a heavier machine. A 24″ wheel with 34 teeth is common for robust performance, while 16 teeth on a 24″ wheel suits lighter tasks.
- Power source and mobility: PTO-powered grinders suit standard tractors; hydraulic machines offer precise control on compatible tractors; gas-powered units provide mobility where tractors aren’t available.
- Teeth durability and replacement: Carbide teeth last longer and maintain sharpness through more cycles. Confirm compatibility for turning or replacing worn teeth to maximize lifespan.
- Maintenance features: Onboard tool storage, protective hardware, and simple maintenance routines reduce downtime in fieldwork.
- Safety and ergonomics: Look for guarding, operator safety stops, and stable mounting to prevent injuries and ensure smooth operation on uneven terrain.
- Cost of ownership: Include availability of spare parts, tooth sets, and maintenance kits; consider long-term maintenance costs beyond initial purchase price.
- Application scope: Choose models suitable for forestry, park maintenance, orchards, farms, and landscape renovations based on stump size, number of stumps, and soil conditions.
Selecting the right stump grinder depends on your tractor horsepower, worksite conditions, and the balance between mobility and grinding power. For frequent, professional use, hydraulic or PTO-powered units with durable carbide teeth and a robust cutting wheel provide consistent performance. For smaller properties or occasional use, gas-powered grinders with a larger cutting height can offer portable, self-contained operation. Always confirm compatibility with specific tractor brands and implement a safe operation plan before work begins.
