The SP4012 series is a four-wheeled self-propelled unit designed to deliver maximum cutting power in hard to get to areas. A unique dual speed ground system allows the SP4012 to travel faster than any other stump cutter on the market today.

The unit also boasts a 1-inch thick, 21-inch diameter cutting wheel, letting you grind faster and smoother than ever before. The SP4012 features heavy-duty construction (1,550 pounds), hydraulic steering and four-wheel stance. This combination offers unmatched stability and maneuverability.

This compact machine has a width of 35 inches, allowing it to fit easily through standard backyard gates. The SP4012 incorpo rates many of the features found in larger Carlton models including a direct drive hydraulic pump, hardened bushings and shafts, counter balance valves on the lift, swing and hydraulic drive circuits.

With its wide range of features and dependable construction, the SP4012 is designed to maximize production and profits, while minimizing downtime.


Optional Dual Wheels are easily removed. One bolt and you are through the back gate.

Hydraulic Steering allows precise control and operation while minimizing operator fatigue.

A 30-inch tongue cylinder gives the operator a more controlled progression into the stump when precision is a must like when cutting against a chain link fence or sidewalk.

Dual Speed Ground Drive System makes the SP4012 the fastest Self-Propelled machine available!
