Our largest construction excavator, the powerful PC850-8E0 SE (Super Earthmover) combines a powerful digging force with a variety of operating modes to maximise machine productivity and efficiency. As with all our construction excavators, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.

Features and benefits
Electronically controlled variable speed fan
The electronic control system sets the revolution speed of the cooling fan according ro the coolant, hydraulic oil, and ambient temperature; effectively uses the engine output to prevent wasteful consumption; and reduces noise during low-speed fan revolution
Two-mode setting for boom
Smooth mode provides easy operation for gathering blasted rock and scraping operations. When maximum digging force is needed, switch to power mode for more effective excavating.
Comfortable working space
The wide spacious cab includes a seat with reclining backrest. The seat height and position are easily adjusted using a pull-up lever. The armrest position is easily adjusted together with the console. Reclining the seat further enables it to be fully laid back with the headrest attached.
