Komatsu 845

The profit-driving forwarder with low enviromental impact

Komatsu 845

The Komatsu 845 is built to provide the highest possible productivity in thinning and lighter clear cutting. At the same time, it's the forwarder that delivers the best conceivable operating economy but without causing undue impact on the environmental. Here are the 845's most significant strength:


Flexible load area

Flexible load area and new FlexBunk bunks with mechanical widening and hydraulic stake height adjustment enable a 12-ton load capacity regardless of timber lenght.

Minimal impact on the environment

The 845's superior manoeuvrability, acessibility and the minimal impact on the environment, as well as its low ground pressure and high clearance, are all due to the machine's low weight, slim exterior dimensions and 26.5 inch wheels.

Intelligent hydrostatic system

Computerized system (optimizes hydrostatic characteristics to: machine load, ground conditions, slope, obstacles, power and torque output from diesel engine). Enables good diesel engine utilization on low revs with high tractive force and good fuel economy. Reliability – Overspeed protection for hydrostatic motor.
