| John Deere Enhances its Forestry Machines ![]() "These performance and functionality enhancements are driven by ongoing customer feedback, which we continuously integrate into our machines," said Jim O'Halloran, global product marketing manager at John Deere. "The updated operator features and improvements on our 900 Series models empower operators to maximize efficiency with simplified functionality, for exceptional productivity." The Dedicated Travel System isolates the travel functions from the other functions on the machine. This enables the operator to focus on the task at hand by not allowing boom and swing operations to interfere and slow down the travel functions. In addition, the power balance and availability has been optimized and can be adjusted between the upper and travel functions, allowing priority to the needed operations. Dedicated Travel is standard on the 859M, 953M, and 959M Feller Bunchers, as well as the 959ML Shovel Logger. It remains optional on 853M and 903M Feller Bunchers and 859MH and 959MH Harvesters. The new one-touch Return-To-Level functionality combines multiple leveling system adjustments into one push-and-hold operator input. As the machine moves to a different slope, the rotating upper can be brought to a level position (based on the parameters of the leveling system) by utilizing a simple button function on the joystick. The individual leveling control buttons will remain. This new operator assistance feature has been combined with the field-proven John Deere Slope Monitoring system, which actively measures and displays the slope of the terrain to the operator. These two advanced features allow the operator to focus more on the application machine adjustments. They are available as the new Slope Management System, which is available as an optional upgrade on all John Deere 800 and 900 Series leveling feller bunchers, harvesters, and shovel loggers. In addition to these new performance and productivity features, all 800 and 900 Series leveling feller buncher, harvester and shovel logger models received improvements to the leveling system cylinder pin joints. The leveling cylinder pins have been updated with a larger diameter, tighter machining tolerances, and an improved grease path, enhancing the initial fit and ensuring grease is directed precisely where needed. These updates reduce bearing stresses under load and improve the system's overall performance. Also, on all 800 and 900 undercarriages, the track frame steps are now welded onto the machine's frame with additional gusseting to help strengthen them against impact. write your comments about the article :: © 2025 Construction News :: home page |
