Features
Easy-to-Use G5ᴾˡᵘˢ CommandCenter™ Display Shows All Important Harvest Data

The G5ᴾˡᵘˢ CommandCenter™ is the main display system, offering a 12.8-in. (32.5-cm) touchscreen that provides customizable harvest and diagnostic information. It improves operator efficiency with intuitive navigation, 10% fewer button presses than the previous design, and shortcut keys for quick access to key functions.
Ground Speed Automation Dynamically Adjusts Combine

Ground speed automation actively adjusts a combine’s speed during harvest by analyzing terrain, previous coverage, grain loss, engine power, header height, and operator-defined speed limits. This system shifts the focus from fixed-speed harvesting to maintaining consistent crop throughput, allowing operators to concentrate on other harvesting tasks.
A New Level of Luxury in the Ultimate Comfort and Convenience Package

The seat features 16-degree swivel, electronic adjustments, heating, cooling, massage, and pneumatic lumbar support for comfort during long harvests. The cab includes a 6.5-in. (16.5-cm) touchscreen radio with Apple CarPlay® and Android Auto™, a door cinch for easy sealing, floor vents for climate control, and ample storage with five cup holders.
