2-in-1 tracked trencher and stump grinder CIMEX BM-27PRO BeaverMax

CIMEX BeaverMax BM-27PRO is a professional self-propelled machine with hydraulic drive that combines two functions on one chassis: stump grinding and trenching. Interchangeable front attachments allow the machine to be adapted to the task.

• Grinding and removal of tree stumps
• Digging narrow trenches for cables, pipes, irrigation systems and drainage

This versatility makes the BM-27PRO a practical solution for landscaping contractors, construction crews, utility installers and professional grounds-maintenance teams.

The undercarriage and working attachments are hydraulically driven, providing smooth operation, strong traction and dependable performance under demanding conditions. A two-cylinder RATO R740 petrol engine delivers 27 hp from 740 cc, supplying the torque required for both stump-grinding and trenching configurations.

As a stump grinder, the BM-27PRO uses a 370 mm cutting wheel with 12 carbide teeth. It can process stumps up to 600 mm high and grind down to 235 mm below ground level. Hydraulic arm movement and joystick controls support precise positioning of the cutting wheel.

The 150 mm (5.9 in) rubber tracks provide stability and traction on soft, sloping or uneven terrain. Independent track control improves manoeuvrability around buildings, fences and infrastructure. Travel speed is up to 5 km/h forward and 2.4 km/h in reverse.

With the trenching attachment installed on the same main arm, the BM-27PRO cuts narrow, consistent trenches for cables, pipes, communications, irrigation and drainage. Combining both functions reduces the need to purchase and transport two separate machines.

The reinforced frame, sealed bearings and accessible service points are designed for professional use and straightforward maintenance. Protective guards, emergency shut-off and speed controls support safe operation when the machine is used according to its operating instructions.

Key advantages

• Two machines on one chassis: interchangeable stump-grinding and trenching attachments.
• Self-propelled hydraulic platform: hydraulic travel and working functions for smooth, controlled operation.
• Stable on varied terrain: rubber tracks provide traction on grass, soft ground, slopes and uneven surfaces.
• 27 hp two-cylinder engine: ample power for intensive stump-grinding and trenching work.
• Precise joystick control: independent control of travel, arm movement, cutting-wheel position and attachment drive.
• Compact manoeuvrability: suitable for positioning in restricted work areas.
• Professional construction: reinforced chassis, sealed bearings and accessible service points.
