Five years in the making. Backed by over a half-century of experience in the woods. To build a better swing machine, we went to you, our customer. Through our Customer Advocate Group (CAG), we collected invaluable input from loggers just like you — the ones who live it every day. Then we spent thousands of hours testing the machines until we got them exactly right. You spoke. We listened. We responded with a major cab update that sets a new standard for comfort and safety — improvements that you won’t be able to imagine living without. And as always, there are a host of other new features...

RUGGED, RELIABLE, AND READY TO RUMBLE Dishes it out. And takes it. You never quit, and neither will your G-Series Swing Machine. Because in the forest, uptime isn't everything. It's the only thing. Simplified electrical system More reliable electrical architecture simplifies wiring harnesses and minimizes the number of fuses and relays needed, eliminating 30 percent of the electrical connectors. JDLink™ enables quick fault detection and troubleshooting. More robust cooling system Larger, higher-capacity coolers and improved airflow help reduce hydraulic operating temperature, for maximum...

STANDOUT FEATURE Improved visibility Countless hours of virtual-reality studies and fieldtesting with loggers led to superb all-around visibility.

Polycarbonate windows durably meet safety requirements. Easy-to-read monitor Multi-language color LCD monitor provides intuitive access to a wealth of machine data and functions. Better access A staircase at the rear of the machine eases cab entry and exit, for more stable footing...

Truly visionary. Designed by loggers for loggers, two cab options provide significantly more operator comfort. Forestry-excavator cab is 25-percent larger than previous models.

Other fatigue-beating creature comforts include efficient climate control, heated/cooled seats, ergonomic controls, and XM Satellite Radio™-ready system. The cab is a big step forward, with more comfort and better visibility. It’s really...
