Efficient and Powerful Stump Removal

The Cobra SG15L is a high-performance stump grinder engineered to tackle the challenging task of removing tree stumps and root systems. It is an ideal machine for professional landscapers, tree surgeons, and property owners dealing with land clearance. With its robust construction and powerful engine, it provides an effective solution for clearing unwanted stumps efficiently.

High-Performance Loncin Engine

At the core of the SG15L is a formidable 15hp Loncin G420 engine. This easy-starting, air-cooled four-stroke engine delivers the consistent power and torque required to grind through tough wood with ease. Loncin engines are renowned for their reliability, ensuring the SG15L is ready to perform whenever needed.

Superior Cutting Capability

The SG15L boasts an impressive cutting range, capable of grinding stumps from 600mm above ground down to 235mm below the surface. This versatility allows for complete stump removal, leaving the ground ready for new landscaping or construction. The 300mm diameter cutting wheel is 90mm thick and equipped with 9 heavy-duty tungsten carbide teeth, which are exceptionally durable and provide excellent grinding results, turning dense stumps into manageable wood chips.

Effortless Manoeuvrability

Despite its substantial 110kg weight, the Cobra SG15L is surprisingly easy to manoeuvre thanks to its self-propelled drive system. This feature, combined with large pneumatic tyres, allows the operator to effortlessly move the machine across uneven ground and position it precisely for grinding. As Cobra states, their machinery is “expertly designed in the U.K to cater specifically for the changing conditions of the British lawn,” and the SG15L’s handling is a testament to this philosophy.

Frequently Asked Questions

Frequently Asked Questions

Who is the Cobra SG15L stump grinder suitable for?

The SG15L is designed for a range of users, including professional tree surgeons, landscapers, and landowners with significant property to maintain. Its 15hp engine and robust build make it capable of tackling frequent and demanding stump removal tasks.

How deep can the SG15L grind a stump?

The Cobra SG15L can grind stumps down to a depth of 235mm (approximately 9 inches) below ground level. It can also tackle stumps that are up to 600mm (approximately 23.5 inches) above ground.

What makes the tungsten carbide teeth effective?

Tungsten carbide is an extremely hard and durable material. The 9 heavy-duty teeth on the SG15L’s cutting wheel can withstand the high impact of grinding dense wood, maintaining their sharpness for longer and providing a more efficient cutting action compared to standard steel teeth.

When you purchase from Sims Garden Machinery, you can be assured that your stump grinder will not require complex assembly. Our trained mechanics perform a full Pre-Delivery Inspection (PDI), which includes assembly and testing.
