When a massive tree is dropped in a tight, fenced-in residential backyard, getting a massive tow-behind grinder to the stump is usually impossible. The Dosko 13hp Stump Grinder is specifically engineered to solve this problem, offering an incredibly narrow, compact footprint that easily rolls through standard garden gates and narrow walkways.
At the center of this heavy-duty machine is an industrial 389cc Honda GX390 engine. Highly respected by commercial landscapers, this legendary power plant delivers the unyielding torque necessary to aggressively power through the hardest wood species without ever bogging down or stalling.
To maximize cutting efficiency, this grinder is equipped with a massive 14-inch cutting disc spinning at a blistering 2200 RPM. Armed with an 8-tooth Greenteeth 700 series setup, this machine aggressively shears stumps a massive 20 inches above grade and chases the roots a full 16 inches underground.
For contractors looking to completely eliminate the physical fatigue of stump grinding, Dosko offers this machine with an optional Swivel Action base (337S-13HC). This advanced feature allows the operator to lock the wheels in place and effortlessly sweep the entire cutting head left and right over the stump, drastically reducing the effort required to make a pass.
Standard grinders rely on weak centrifugal clutches that constantly slip and burn out under heavy loads. Both of these units bypass that entirely by utilizing a heavy-duty direct belt drive with a 3-groove power band, ensuring flawless, slip-free power transfer from the Honda engine straight to the massive cutting disc.
Maneuvering a 300-pound machine requires serious leverage, which is why the Dosko 13hp Stump Grinder features a 5-position adjustable handlebar. Combined with a unique side-discharge frame that blasts mulch away from the operator, this machine guarantees your crew stays comfortable, safe, and highly productive all day long.
Commercial Honda Reliability
Standard residential engines simply cannot handle the violent, continuous vibration of stump grinding. This machine is powered by the legendary Honda GX390 engine, providing the bulletproof reliability and extreme torque required for daily commercial operation.
Effortless Swivel Upgrade
Wrestling a heavy grinder back and forth for hours will quickly exhaust a single operator. The upgraded swivel-action model (337S-13HC) features a specialized pivoting base that allows the operator to effortlessly sweep the grinding head left and right, completely eliminating lower back fatigue.
Advanced Shearing Action
Standard grinding teeth aggressively rip at the wood, causing violent machine kickback. This unit utilizes a premium Greenteeth setup with a unique concave "dish" design that smoothly shears the wood, drastically reducing vibration and operator fatigue.
Triple Blade Economy
Shutting down a jobsite just to sharpen dull grinding teeth wastes valuable daylight. Because this machine utilizes a specialized Greenteeth system, your crew can simply unbolt the tooth and rotate it 120 degrees, effectively giving you three brand-new cutting edges per tooth.
Direct Drive Efficiency
Centrifugal clutches are notorious for slipping and burning out when forced to spin heavy steel cutting wheels through dense wood. This unit utilizes a heavy-duty direct belt drive with a 3-groove power band, ensuring flawless, slip-free power transfer and preventing costly jobsite downtime.
Massive Grinding Depth
Shaving a stump flush with the lawn doesn't solve the problem; the roots will eventually heave the driveway or ruin the sod. This grinder is engineered to chase the root system an incredible 16 inches below ground, ensuring the stump is completely and permanently eradicated.
Clean Side-Discharge
Many walk-behind grinders blast heavy woodchips and dirt straight back into the operator's shins. This machine is built with a highly specialized side-discharge frame that actively throws the heavy debris away from your crew, making the job significantly safer and much cleaner.
