Operating for long hours is common. As the day goes on, maintaining consistent productivity is important. One factor in keeping high, consistent productivity is a comfortable operating environment. The M-series boasts greatly increased window area for better visibility and more cab space over prior models. Low-effort electrohydraulic (EH) controls allow you to customize the button and lever layout to your preference and save your settings when switching between operators.

• Large and spacious operator station designed with operator input

• Ergonomic controls and increased cab volume over prior models

Intelligent Boom Control (IBC) smooths boom operations, making them more precise and efficient, to increase operator productivity compared to a Deere tracked harvester without IBC. With IBC, you no longer need to control each boom function independently. Just control the direction of the head with a single lever command, and IBC will automatically guide the boom and cylinders accordingly. IBC also utilizes adaptive swing control to adjust the swing speed based on the overall position of the head. This makes controlling the head more precise and intuitive, especially for new operators, compared to machines without IBC.

• Customizable control pattern and boom motions

• More efficient and consistent boom movements

• Enhanced cylinder cushioning reduces shock loading at end-of-stroke

• Overall improved operator experience

• Simple and intuitive to operate
