Got Stumps? Let’s Talk Solutions

A tree removal may feel like a victory in its own right, but, for many homeowners, it’s just the start of the battle. Tough stumps can mar your outdoor space. The last thing you want to do is get heavy machinery, like a bulldozer or large excavator; this heavy-handed approach risks causing all sorts of unwanted damage because those kinds of machines are sure to destroy your lawn. So, what’s the solution? Stump grinders. These machines are purpose built to turn an entire stump into a pile of wood chips in short order. 

In this post, we break down the five most important elements to consider for choosing a stump grinder, and we answer some other common questions people have about this type of machinery. 

How Stump Grinders Work

Stump grinders are unimaginatively named because they are built for one purpose: grinding away tree stumps! Just as with wood working tools, there are several ways to accomplish the same goal, but most residential stump grinders work with the same basic mechanical setup–a high-speed grinding wheel with sharp blades or teeth that tear into the wood and break it down into fine wood chips. The process is comparable to how a circular saw cuts through materials, but here the goal is to grind the stump until it’s level with—or below—the surrounding ground.

Using a stump grinder is surprisingly straightforward. Start by positioning the machine over the stump and set it to match the size of the stump, along with the desired grinding depth. With the grinder activated, guide the cutting wheel steadily back and forth across the stump as many times as needed to take it down to your desired level. 

Choosing a Stump Grinder: 5 Key Elements to Consider

1. Type of Stump Grinder

There are several different types of stump grinders available in today’s market. Walk-behind stump grinders are a go-to option for smaller stumps and tighter spaces. If you’re working on uneven terrain or tackling larger, tougher stumps, a tracked stump grinder may be more effective, thanks to its added stability and power.

For those who already own a skid steer, a stump grinder attachment might be the smartest option. These attachments turn your existing machine into a stump-removal powerhouse, saving time and maximizing efficiency. Consider the scale of your project, the stump’s location, and how easily the grinder needs to travel to the job site before making your choice.

2. Power and Cutting Capacity

The engine power and cutting wheel size of a stump grinder determine how efficiently it can grind stumps. A smaller model is enough for most residential projects. For very large stumps or large-scale projects, machines with higher horsepower will grind faster and handle hardwood with ease. However, for smaller tasks, such robust equipment may be unnecessary.

3. Cutting Depth 

Cutting depth plays a major role in stump removal. For most residential applications, a grinder that cuts 10 to 12 inches below ground level is sufficient. If your goal is complete stump removal, including roots, deeper grinding—up to 20 inches—may be necessary, as most roots are found in the top 18 inches.

4. Maneuverability and Accessibility

Think about where you’ll be working. Tight spaces call for compact, wheeled stump grinders that can navigate small garden paths or densely landscaped areas. On the other hand, if the ground is uneven or the stumps are particularly large, tracked stump grinders provide better stability and traction.

Features like adjustable handles and cushioned grips can also enhance operator comfort, especially for lengthy jobs. The right stump grinder isn’t just about power—it’s about ease of use and adaptability to your work environment.

5. Maintenance and Durability

When investing in or renting equipment, reliability matters. Machines with reinforced frames, robust wheels, and easily accessible maintenance points are more likely to withstand repeated use. Regular care, such as sharpening the cutting wheel and removing debris after use, will also extend the machine’s lifespan.

Rentco ensures its rental equipment, including the SG1301H, is maintained to the highest standards. This means you’ll always receive a grinder that’s ready to perform, saving you time and hassle on the job site.

How Deep Do Stump Grinders Go?

The depth a grinder can achieve varies by model. Walk-behind grinders, such as the Billy Goat SG1301H, can reach depths of 10 to 12 inches below ground level—perfect for prepping a garden or laying new lawn soil. 

If you’re dealing with larger stumps, tracked stump grinder models might be the better choice. These machines often cut as deep as 20 inches, which takes care of the root system as well. 

Are Stump Grinders Easy to Use?

If you’ve never worked with one, it’s a natural question. The good news is that if you’re someone who doesn’t mind (or even enjoys) working with power tools then you should have an easy time. 

Safety, however, is non-negotiable. Always wear protective gear, including gloves, goggles, and sturdy footwear, to shield yourself from flying wood chips and debris. Clearing the work area beforehand is another essential step—remove rocks and any loose materials that could interfere with the grinder.

Remember: stump grinding is not a race! When you work with powerful machines, take your time. They will make short work of the project anyway, there’s no need to risk a costly mistake or serious accident.
