Dual Spindle Cutter – Heavy Duty

The Blue Diamond® Heavy Duty Dual Spindle Cutters are built for tough mowing and land-clearing applications, handling weeds, grass, and brush up to 3” in diameter. Designed for 42–52 HP tractors and available in 8’ and 10’ widths, these cutters maximize productivity with wide coverage.

Featuring a dual spindle design with free-swinging blades, they reduce impact shock when hitting obstacles, improving durability and performance. A slip clutch and dual shock couplers protect the driveline and gearboxes, while front and rear chain and driveline guards enhance operator safety.
