The Stout Skid Steer Stump Grinder gives you a compact, maneuverable way to grind stumps without bringing in a dedicated grinder. A 26″ cutting wheel with 20 carbide teeth lets the attachment work through stumps and roots while reaching up to 11″ below grade for a cleaner finished surface.
Choose Standard Flow for machines producing 15–20 GPM or High Flow for machines producing 20–30 GPM. Both versions use a universal skid steer quick attach mount and 1/2″ flat-face hydraulic couplers, making the grinder a practical fit for a wide range of skid steers and compact track loaders.
What is the difference between the Standard Flow and High Flow Stout stump grinders?
The main difference is the hydraulic motor configuration. The Standard Flow version is designed for machines producing 15–20 GPM, while the High Flow version is designed for 20–30 GPM.
Which version should I order for my skid steer?
Choose the version that matches your machine’s auxiliary hydraulic flow. Check the machine specifications before ordering rather than choosing based only on whether the machine is marketed as “standard flow” or “high flow.”
How large is the cutting wheel?
Both versions use a 26″ diameter cutting wheel.
How many teeth are on the cutting wheel?
The stump grinder uses 20 carbide cutting teeth.
How deep can the grinder cut below ground level?
Stout rates the grinder for cutting up to 11″ below grade.
Does the High Flow version grind deeper than the Standard Flow version?
No. Both versions use the same 26″ cutting wheel and have the same 11″ below-grade cutting depth. The High Flow model is configured for machines with greater auxiliary hydraulic flow.
What mount does the stump grinder use?
Both versions use the J2513 universal skid steer quick attach interface.
What hydraulic couplers does it use?
The grinder comes configured with 1/2″ flat-face hydraulic couplers.
Will it work on a compact track loader?
Yes, provided the machine uses a compatible universal skid steer quick attach and its auxiliary hydraulic flow falls within the range of the selected grinder.
How much does the stump grinder weigh?
The Standard Flow version weighs approximately 615 Lbs., while the High Flow version weighs approximately 625 Lbs.
Can I use the High Flow model on a machine producing more than 30 GPM?
Stout specifies a maximum hydraulic flow of 30 GPM for the High Flow grinder. Do not operate it above the manufacturer’s specified hydraulic range without confirming an appropriate hydraulic setup.
Are the carbide teeth considered wear items?
Yes. Cutting teeth are ground-engaging wear components and will wear with normal use.
Note: Compatibility depends on your machine’s auxiliary hydraulic flow, universal skid steer quick attach, hydraulic couplers, operating capacity, and specific year/configuration. The Standard Flow grinder requires 15–20 GPM; the High Flow grinder requires 20–30 GPM. Always verify your machine’s actual hydraulic specifications before ordering. A model appearing below does not guarantee compatibility with every configuration.

Stout provides a 12-month limited manufacturer warranty covering defects in materials and workmanship for the original purchaser.
Normal wear items, including bearings, hoses, teeth, cutting edges, and other ground-engaging components, are excluded from warranty coverage. Damage caused by improper use, installation, adjustment, maintenance, or modification is also excluded. If you have a warranty question or claim, contact us and we’ll help connect you with Stout and get the process started.
Bring the grinder to the stump.
Using the skid steer as the carrier gives you the maneuverability to work around landscaping, buildings, fences, and other areas where a larger dedicated stump grinder may be cumbersome.
Choose the motor that matches your machine.
Standard and High Flow configurations let you match the grinder to your machine’s actual auxiliary hydraulic output rather than forcing one hydraulic setup across every skid steer.
Grind below the finished surface.
An 11″ below-grade cutting depth helps remove more of the stump and upper root mass so the area can be backfilled, graded, or replanted.
Keep one attachment useful across different jobs.
The universal skid steer mount and straightforward hydraulic connection make it a practical attachment for tree removal, property cleanup, landscaping, and site preparation work.
