FAQs
1. Is it worth buying a PTO stump grinder, and is it difficult to operate?
Yes, investing in a PTO-driven stump grinder like the Farmry SG24 is highly worthwhile for landowners, contractors, and property managers. Its rugged gear box, paired with a heavy-duty gear box and a robust 24-inch cutting wheel, delivers more efficient grinding performance. By gradually removing layers of wood with its staggered carbide teeth, it ensures safe, controlled, and efficient grinding performance without overloading the machine. The process is designed to be simple to operate using your tractor's 3-point hitch, making it easy even for non-professionals.
2. What is the recommended PTO speed for operating the grinder?
The SG24 operates optimally at a PTO speed of 540 RPM. This standard PTO HP input ensures efficient grinding performance while reducing wear on the drive system. Maintaining the correct wheel speed and PTO speed balance helps prevent excessive vibration, promoting smoother operation and extending the lifespan of both the stump grinder and your tractor.
3. How does the SG24 stump grinder protect my tractor and reduce long-term wear?
The SG24 is designed with a slip clutch and rugged gear box to handle tough jobs while safeguarding your PTO system. Its heavy flywheel, coupled with greaseable pins and durable construction, ensures less shock to the tractor when the cutting wheel engages. This setup helps protect the driveline, extending your tractor’s life and reducing expensive repairs—especially when grinding hard stumps over many business days of use.
4. Are the cutting teeth and mounting hardware built to last, and can I replace them easily?
Absolutely. The SG24 uses carbide steel bolt-on teeth designed for durability and long service life, even when cutting dense hardwood stumps. These replacement teeth are easy to swap out, ensuring less downtime and uninterrupted work. Regularly inspecting the cutting wheel, wheel thickness, and teeth helps maintain efficient cutting depth and performance.
5. Does the SG24 offer precise control for different stump conditions and cutting heights?
Yes. The SG24 provides total angle and cutting height control by allowing the operator to adjust the grinder using the tractor’s 3-point hitch and hydraulics. As the tractor moves, you can tilt or pivot the cutting wheel side-to-side for clean grinding on uneven terrain or awkward stump shapes. This control helps maintain a consistent cutting depth while ensuring flush, level stump removal.
