John Deere Equips 900M-Series Tracked Feller Bunchers and 900MH-Series Harvesters With Final Tier 4 Engines

MOLINE, Ill. (November 03, 2017) – The John Deere 900M-Series Tracked Feller Bunchers and 900MH-Series Harvesters are now equipped with Final Tier 4 (FT4) engines, offering fuel and fluid-efficient machines without sacrificing power and performance. John Deere is the leader in FT4 technology, offering a diesel particulate filter (DPF) solution that is known for its ability to reduce the dependency of diesel exhaust fluid (DEF). Built on decades of John Deere engine experience and millions of hours of FT4 runtime, the 900M-Series and 900MH-Series machines deliver premium performance, optimum fluid efficiency, increased reliability and economical operating costs.

"Out in the woods, machine productivity and uptime are crucial to business success. Our FT4 engine and emission solutions have been rigorously tested and in the most extreme applications, loggers can be confident that their tracked feller buncher or harvester can withstand even the most challenging conditions," said Jim O'Halloran, product marketing manager for John Deere. "As a proven partner offering the most comprehensive solutions in the industry, John Deere is proud to offer loggers a powerful, reliable machine that meets current and future emissions standards."

With the required emissions change, John Deere FT4 engines maintain power density, torque, and transient response – which results in productivity, uptime, and more value for your machines. In addition to excellent fuel economy, the design of the engine after-treatment system results in exceptionally low Diesel Exhaust Fluid (DEF) usage. "DEF usage has become a real input into the planning and cost of the overall equipment operation," says O'Halloran. "We have to talk about overall fluid economy now, and if you use less fluid, there is less handling and storage requirements. It's a real positive factor in the efficiency and overall bottom line of our Customers."

John Deere has also made changes to the machine line-up, and improving the structure, design and horsepower on select machines. John Deere offers three 900M-Series tracked feller buncher models, the 903M953M flat bottom and 959M leveling machines, as well as two 900MH-Series harvesters, the 953MH flat bottom and 959MH leveling machines. All of the 900M-Series and 900MH-Series machines feature a redesigned engine enclosure, improving structural strength while maintaining the excellent serviceability that John Deere machines are known for. In addition to all of the 900M-Series and 900MH-Series machines now boasting 330 horsepower (224 KW), the 959M Feller Buncher and 959MH Harvester continue to have best in class leveling envelope, maximizing operator comfort and performance requirements in demanding steep slope logging applications.

Other updates include an improved LED work lighting option, and the expansion of the Disc Saw Felling Head option availability. This includes the 22-inch (56 Centimeters) felling head, which is now available for all of the 900M-Series tracked feller bunchers.

The John Deere M-Series and MH-Series machines are available with JDLink™ five years in base. JDLink remotely connects owners and managers to their machines and dealers, providing alerts and machine information to better manage where and how equipment is used.
