Komatsu 901

Strong and nimble harvester

Komatsu 901

The Komatsu 901 harvester is both agile and powerful for its size. With its high productivity and operator comfort it is optimal for thinning. It has high work capacity and the possibility to operate several crane and head functions at the same time, keeping low fuel consumption.


Revolutionary 3-pump hydraulics

The 901's immense work capacity is much due to the brand new 3-pump hydraulics, split into dual circuits with separate pressure levels. The system is power-regulated against the diesel engine and offers a class-leading hydraulic capacity of 400 l/min. Unique pressure and flow optimisation enables you to work considerably faster without losing hydraulic power. You can operate several crane and head functions simultaneously with maximum hydraulic power, such as slewing the crane, feeding a log and manoeuvring the machine with optimally low fuel consumption.

Large and spacious cab

New large and spacious cab in a new design. Built on our proven, ergonomic and reliable cab concept. Gives a more silent working environment, an exclusive interior with car type material, lots of dedicated storage space,and much more.

Crane placement and stability

The crane's placement together with the large work area provide the Komatsu 901 with unique conditions for high production capacity. The concept is proven and has a simple design, providing market-leading visibility and performance. The coupling between the cab's tilt cylinders and the stabiliser cylinders mounted on the rear axle provides world-class stability. To this we can add the cab's 360-degree rotational ability, which provides a larger work area and enables higher timber concentration and more effective forwarding.
