Buying Guide

When hunting for the best stump grinder, whether for residential or commercial use, choosing the right one for the job is crucial. Here’s a complete buying guide to determine the type and features of the machine that can work best on crushing tree stumps.

Types of Stump Grinder

There are 2 choices for a stump grinder, depending on the size and height of trunk remnants in the yard that needs crushing.

Best Stump Grinder Review and Comprehensive Buying Guide

Handlebar Stump Grinder

This type of stump grinder is the most common of the two. Most affordable units in the market are handlebar stump grinders. They are operator-friendly but requires manual back-and-forth operation when crushing trunk remnants.

Handlebar stump grinders can work on different kinds of stumps up to 14 inches above the ground, depending on the model’s cutting wheel. They are best for residential applications with small-diameter stumps and has a relatively smaller build for space-saving storage.

Track Stump Grinder

This type of track stump grinder works similarly to handlebar types but doesn’t need manual steering during operation. Instead, track stump grinders feature a control pad used to move or maneuver the unit. They are best for use in crushing more massive and higher tree stumps of up to 35 inches tall.

Truck stump grinders are also better at distributing their weight, which is ideal for use in delicate plots. They don’t produce massive ground pressure when used, so there is no risk of creating turn marks on the turf.

However, track stump grinders usually have more massive build than handlebar types. That makes it more challenging for this type of stump grinder in terms of storage, and it also requires a separate trailing unit for transport. Plus, they are the more expensive type of stump grinder.

Work Type

Ensure that a stump grinder is one that can complete the landscaping job on hand at the highest standard possible. However, that doesn’t mean buying the stump grinder with the highest power. That won’t be ideal if the machine’s intended use is only for crushing small tree remnants in the backyard.

That is why it’s vital to determine what type of stump grinding work the machine will likely to do before buying one. For residential use, most portable root cutters will do. Meanwhile, industrial and professional stump grinding jobs may require a more massive and powerful unit.

The key is finding the best stump grinder for the intended use. A good rule of thumb for this is to buy a small stump grinder for small-scale jobs and a big unit for big-scale jobs.

Cutting Capacity

In terms of cutting capacity, there are several things to consider. The first one is the cutting speed of the stump grinder. Higher RPM or revolutions per minute will make the job done quickly, and it helps for a smoother finish as well.

The second thing to look out for is the height and thickness of the cutting wheel. The cutting wheel will indicate the height of tree stumps a machine can work with, both above and below the ground surface.

The number of teeth on the blade will also determine the smoothness of the grinding finish of the unit. Its strength and cutting-edge mechanism also define how equipped the machine is in crushing the tree remnants that need clearing.


Manually crushing tree stumps is nearly impossible, but a stump grinder can get the job done faster and more accurately. In terms of efficiency, the stump grinder should have sufficient power strength and engine capacity to finish the job well.

The key is to find efficient machines based on the intensity of work, so there are no chances of the stump grinder bogging down while on the job.


Stump grinders come in varying sizes. Smaller units are best for residential use and in crushing low to moderately sized tree stumps. They are easy to transport and needs lesser area for storage.

Meanwhile, stump grinders for commercial and professional use will substantially have a bigger build. Their more massive size is so they can remove big-diameter stumps at a faster rate.

Ease of Use

It makes the job done quicker if the stump grinder is easy to use. Look out for a unit with an easy-start function and straightforward controls. That includes the stump grinder’s braking features to get optimum control on the machine during the grinding process.


Safety is a vital feature to look out for when buying the best stump grinder, whether its for residential or professional use. Some of the standard safety features for a stump grinder includes wheel stability and sturdy handle frames.

In case of emergency, automatic break buttons and tank shutoff options are also crucial to have in a stump grinder.


Getting rid of tree stumps doesn’t have to be awkward and exhausting when using a stump grinder. Look out for a unit that has ergonomically designed handlebars for optimum grip and comfort. Adjustable handles also work best to fit different statures and positions, especially when steering the stump grinder.

Check out for the maneuvering specifications of the unit before buying. A stump grinder should require minimal intervention to do its job efficiently.


Most stump grinders are gas-powered units that require fuel and oil refilling, depending on the tank capacity. This type of machine will also need regular cleaning and maintenance to preserve its good condition. However, some engines have excellent features like an OHV system that makes it cost-effective and easier to maintain.

Check out if the stump grinder has a lot of moving parts that will require stricter maintenance. Depending on the material quality of the teeth, it might also need frequent sharpening.


Stump grinders come at varying prices. Some are affordable options and have enough power and grinding performance for residential jobs. Meanwhile, commercial grinding machines are more expensive with higher engine power.

The key is to determine the features for a stump grinder based on its intended use, then find a competitively priced unit that fits those needs.


Of all the stump grinders in the market, the Samson Machinery Stump Grinder offers the best value for money. It’s an affordable and user-friendly unit with optimum stump grinding performance with its impressive 15HP 420cc engine, OHV 4-Stroke System, and 12-inches cutting wheel.
