Designed to meet the demanding requirements of professionals in the forestry, landscaping, and municipal service industries, the CORMAK Stump Grinder is a high-performance machine equipped with a powerful 12 HP petrol engine with a 420 cm³ displacement. It has been engineered for efficient removal of tree stumps after felling, eliminating the need for costly and time-consuming excavation or the use of chemical treatments.

Main Advantages and Design Features

Powerful drive unit – the 12 HP (420 cm³) petrol engine provides high torque required for working with hard wood and deep root systems.
Precision cutting system – the cutting wheel is equipped with durable, multiple-hardened cutting teeth, ensuring fast and effective stump grinding below ground level.
Ergonomics and mobility – the optimized design, approximately 113 kg weight, and balanced center of gravity allow easy maneuvering even in hard-to-reach areas such as narrow gates and private gardens.
Heavy-duty industrial frame – manufactured from thick-wall steel profiles with a powder-coated finish, providing excellent resistance to mechanical damage and corrosion.
Operator safety – protective guards and an ergonomic control system positioned within easy reach protect the operator from flying wood chips and debris.

Applications

The CORMAK Stump Grinder is designed for professional landscaping companies, municipal service providers, construction companies preparing sites for development, and demanding private users. It enables complete stump removal to a depth that allows easy lawn seeding or new planting without obstacles from remaining roots or wood residues.
