Investing in a tree stump grinder may not make sense for homeowners who just have a stump or two they need to remove after taking out a tree in the yard.
But those with larger properties in wooded areas who may need to kill a few stumps a year can benefit from owning a grinder as opposed to paying for stump removal, which can cost as much as $500 per stump.
Most stump grinders use 14-horsepower (hp) engines to power a grinder that can grind live or dead stumps up to 20 inches high as deep as 12 inches into the ground. We love the DK2 OPG777 12-Inch Gas Power Stump Grinder thanks to its 14-horsepower engine, 12-inch cutting wheel, 16-gauge steel construction, and maneuverable wheeled design.
This guide will explore what factors to consider when shopping for a machine that will remove those unsightly tree stumps from the yard while listing the best stump grinders on the market.

How We Chose the Best Stump Grinders
In reviewing more than a dozen of the best stump grinders on the market, we used a variety of criteria to narrow the field to produce our list of the top options. Grinding live or dead stumps requires a significant amount of torque, so we limited our search to those grinders with larger engines of at least 14 horsepower. This engine size allows tree root grinders to reach depths of at least 8 inches and as much as 16 inches, which is enough to handle small to medium-size tree stumps.
The best stump grinders are heavy by nature, but they shouldn’t be so heavy that a single person can’t safely operate the machine. With that in mind, we stuck with stump grinders with manageable weights as well as models that feature hitch options that allow them to be towed to and from the jobsite. Finally, durability was a key factor in our selection process. Grinding out tree stumps puts tremendous strain on machinery, so we stuck with models made from heavy-gauge steel that can endure repeated use without falling apart.
Our Top Picks
The list below narrows the field to some of the best stump grinders for mostly residential use and landscaping as well as one of the best professional stump grinders.
These varying types of stump grinders have durable heavy-gauge steel construction, can grind stumps at least 6 inches below ground level, and have features that make them easier to use. Read on to find out the best stump grinder to buy regardless of your needs.

What to Consider When Choosing a Stump Grinder
The horsepower of a stump grinder’s engine, along with the height and depth it can grind, are key considerations when shopping for the best stump grinder. Ahead, learn more about these and other important attributes of the best stump grinders.
Types of Stump Grinders
There are three types of stump grinders: handlebar, track, and riding. Handlebar stump grinders, also called walk-behind stump grinders, consist of a large handlebar from which the operator controls the grinder, two wheels that support the motor, and a large spinning blade that grinds the stump. The operator tilts the grinder backward to maneuver it into place then lowers it to begin grinding stumps. Handlebar stump grinders are best suited for smaller tree stumps.
A track stump grinder sits on two large tracks, not unlike a tank. The operator maneuvers the grinder via a wired remote control or controls mounted to the rear of the machine. Riding stump grinders have a cockpit in which the operator sits to control the grinder. Riding and track stump grinders can cost tens of thousands of dollars, making them more suitable for commercial use.
Horsepower
Most engines on a handlebar stump grinder range between 10 and 15 horsepower. Stump grinders with more horsepower can power larger cutting disks, giving them the ability to cut through larger stumps faster. Stump grinders that have more horsepower are typically large track stump grinders designed for commercial use.
Power Transmission System
When considering stump grinders, you’ll find self-propelled models as well as walk-behind grinders. Smaller handlebar stump grinders require the user to manually push the machine while larger track models are self-propelled, allowing the operator to drive the grinder into place via remote control or side-mounted controls.
Size and Cutting Capacity
The size of the grinder’s cutting wheel determines how quickly it can remove a stump as well as how deep it can cut. Grinders can generally have a cutting capacity that reaches depths of a few inches less than the size of the blade. For example, a 12-inch grinder can reach a maximum depth of 9 inches. There are some models with designs that allow them to cut to depths equal to the size of the blade.
Track stump grinders and riding stump grinders, the largest of the three types, can cut to depths ranging from 10 to 30 inches, heights of 20 to 50 inches, and widths of between 45 and 80 inches.
Walk-behind grinders have a smaller cutting capacity with cutting depths ranging from 5 to 16 inches and heights of 10 to 20 inches, making them suitable for smaller stumps.
Frame Durability
Stump grinders generate a significant amount of torque, much like angle grinders, to power the cutting wheel that grinds out stumps. This force places a significant amount of stress on the machine. The best walk-behind grinders have heavy-gauge steel frames that can endure repeated use without falling apart.
Ease of Use
Stump grinders are considered heavy machinery, with most weighing well over 100 pounds. Weight is vital to consider as most stump grinders for residential use are not power-assisted and require the operator to push them into position. Weights for handlebar stump grinders range from as little as 125 pounds to more than 400 pounds. Stump grinders, much like some bench grinders, have features designed to make them easier to move, including large pneumatic tires and adjustable handlebars.
Additional Features
Stump grinders come with features that make them safer and easier to use, including auto-stop safety bars that operate similarly to safety bars on a walk-behind lawn mower, shutting off the engine to prevent injury when the operator removes pressure from the bar. Track stump grinders have swing-out control stations and remote controls that allow the user to operate the grinder from a safe distance.
Heavier or track stump grinders are equipped with tow bars and large wheels that allow the user to hitch the machine to a truck for transport to the jobsite.
Tips for Using a Stump Grinder
A stump grinder can make quick work of that ugly stump in the middle of the yard, but only if it’s operated correctly. Stump grinders are dangerous machines. First and foremost, take the necessary safety precautions by wearing safety goggles, ear protection, and clothing that covers exposed skin.
While the machine has safeguards to protect the operator, such as guards that block debris and auto-shutoff bars, they won’t prevent harm to bystanders. Cordon off the area around the stump removal area to prevent people or pets from getting too close. Stump grinders are made to grind a few stumps, not rocks. Remove any stones, rocks, or debris from around the stump that may damage the grinder’s blades. A stump grinder may do the job of grinding up the stump, but you’ll need other tools to assist, including a rake, shovel, and chainsaw.
- Wear the appropriate safety gear
- Put boundaries around the area to keep people and pets at a safe distance
- Remove rocks and debris from around the stump
- Have a rake, shove, and chainsaw handy
FAQs
If you’re wondering why stump grinders and tree removal cost so much or just how deep into the earth you need to grind that dead stump, read on for answers to these and other questions about this heavy machinery.
While stump grinders are effective tools, they do not remove or kill tree roots. Stump grinding can lead to pest problems, and stump removal involves a lot of labor and cleanup. The process can be messy and damage the lawn, which can take some time to repair.
The maximum height and depth of the stump grinder’s cutting wheel must coincide with the stump’s overall size to effectively remove all wood materials. Measure the stump before choosing a stump grinder.
Generally speaking, you should grind a stump down 4 to 6 inches below ground level. This depth is deep enough to remove the stump from view while allowing for fill to be applied on top of it and, if desired, grass to grow.
Stump grinders are heavy machinery that requires large blades and powerful, larger engines to drive that blade. Larger engines and the hard metals required for stump grinder blades drive the price of the grinder up.
Not really. While stump grinding does create material termites like to feed on, grinding the stump doesn’t release any scents or create an environment that would necessarily attract termites.
The best use for stump shavings is as mulch in surrounding landscaping. Stump shavings, like the mulch you buy at the store, help the soil retain moisture while serving as an excellent weed barrier.
If roots are not disposed of after stump removal, they will rot and decay over 5 to 10 years. But, softwoods decompose quicker than hardwood varieties.
You can use a stump grinder in the rain—just keep in mind that the weight of the grinder can make it difficult to push in soft soil. The grinder can become stuck or may sink into the ground if it’s too wet.
