Features

Crane operation at its easiest

For a harvester operator, an easily operated crane is important for ensuring a productive working day. With Komatsu Smart Crane, the crane – from the main boom all the way to the tip of the telescopic arm – is controlled with a single, smooth lever movement.

Thanks to the crane’s precision and responsiveness, the operator can easily steer the head where they want it, contributing to a more relaxed way of working. A relaxed operator can keep up a high and steady production during the day and still feel more refreshed at the end of the working day. Advantages that will be seen in both profitability and the operator’s well-being.

Revolutionary 3-pump hydraulics

The 931'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 584 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.

Parallel crane

Fast and powerful parallel crane, easy to operate. Mechanical crane tip control. Rapid out, powerful in. Parallel curve. Agile in thinning. Contributes to lower fuel consumption.

Levelling function

The cab levelling function means that you are always seated levelly and don't need to stretch and strain to maintain good posture.

Service friendly

With easily accessible inspection and service points grouped together, an electronically operated engine hood and vertically mounted fuel and oil filters, the daily service is easily conducted.

Improved off road manoeuvrability

Improved off-road manoeuvrability with higher ground clearance, greater tractive force and improved power steering.
