3-Point PTO Stump Grinder, 34 Carbide Teeth, for 15-45HP Tractors, PTO Shaft Included with Slip Clutch, SG24 Tree Stumps Grinder

A PTO-powered stump removal grinder is one of the most efficient and cost-effective tools for removing tree stumps on your own land.

Instead of renting equipment or hiring contractors, a PTO stump grinder allows you to remove multiple stumps whenever you want—wherever your tractor can work. Powered directly by your tractor, hardened steel cutting teeth grind through wood, roots, and stump material quickly and consistently.

Compared with manual tools or small walk-behind units, PTO stump grinders are built for serious stump grinding, offering better stability, deeper cutting, and far greater productivity over time.

Stump grinding efficiency depends on many factors, including wood type, stump size, moisture level, and density. Improper tractor travel speed can lead to poor grinding results, excessive cutter movement, or unnecessary wear on the equipment.

Farmry’s PRO Series stump grinders are engineered to solve this problem. They are equipped with a GO-STOP visual guidance system, helping operators adjust ground speed in real time based on cutting resistance. This improves grinding efficiency, protects cutting teeth, and extends service life.

Additionally, the PRO model features a patented shock-absorption system, which applies steady pressure during grinding, reduces rebound, and improves overall safety and control—especially when working on larger or harder stumps.

The best stump grinder is typically the largest model your tractor can safely handle.

When choosing a PTO stump grinder, match:

• Your tractor’s PTO horsepower
• 3-point hitch lifting capacity
• Intended stump size and volume

Selecting a properly matched grinder ensures stable operation, protects your equipment, and delivers a smoother stump removal experience over time.

1) Attaching the PTO stump grinder

Before installation, check whether the PTO shaft length needs trimming to fit your tractor. Detailed instructions are provided in the user manual.

Once prepared, attach the stump grinder using the three-point hitch, ensuring all connections are secure.

⚠️ Operating with a PTO shaft angle greater than 20° may damage the equipment. Always adjust the top link so the PTO shaft runs as straight as possible during operation.

2) Engaging the grinder

Start the tractor and engage the PTO. The cutting wheel will begin spinning. With the grinder raised, position it directly above the stump before lowering.

3) Grinding the stump

Begin grinding from one side of the stump, moving back and forth in controlled passes. Gradually lower the grinder level by level until the stump and most surface roots are removed.

This method ensures efficient cutting, reduced strain on the equipment, and consistent results.

Grinding time varies depending on stump size, wood hardness, moisture, and root structure. However, in most real-world conditions, stump grinding is measured in minutes—not hours.

With Farmry stump grinders, many standard tree stumps can be removed in around 15 minutes or less, making them ideal for property maintenance, land clearing, and production work.

Farmry stump grinders are delivered in modular components, designed for easy assembly.

Following the instruction manual:

• Assembly typically takes about 1 hour
