With the powerful G-Series forestry swing machines, 750K and 850K crawler dozers, and 620G and 622G motor graders from John Deere, accessing the timber stand has never been so easy. G-Series forestry swing machines The 2154G, 2654G, 3154G and 3754G forestry excavator models were designed to handle unpredictable land and arm loggers with productive, durable and reliable machines. These machines were designed based on over a half-century of experience, offering customers increased comfort, uptime and performance. A standout feature within the G-Series swing machines is the spacious cab design, which was developed with operator comfort at the forefront. The climate-controlled, roomy cab is quieter than its predecessors, and equipped with ergonomic controls, exceptional window clarity, isolation mounting and optional LED lighting. These features provide operators with not only maximum visibility, resulting in improved jobsite safety, but superb comfort during long workdays, boosting productivity. Electrical components on the G-Series machines have been reduced by 30%, increasing machine uptime by reducing future trouble-shooting for electrical issues. Additionally, the G-Series machines feature increased airflow and lower operating temperatures because of the efficient hydraulic management systems, reversing fans and stronger coolers. Serviceability is also made simpler with enhanced service bays equipped with drop-down work platforms and LED service lights, leading to increased uptime and long-term durability. The 3154G and 3754G models each boast a powerful 9 litre engine, while the smaller 2154G and 2654G models are equipped with 6.8 litre engines. The 3154G features the same hydraulic pump as the 3754G – making them both reliable and durable multifunctioning machines. The 3754G has larger lower rollers and a longer track frame option, while the 2154G and 3154G models have more durable lower rollers. The entire line-up is equipped with more robust components for the arm, boom, mainframe and undercarriage, ultimately increasing machine life and productivity. Crawler Dozers Boasting PowerTech 6.8 litre Final Tier 4 (FT4) diesel engines with 165 The 2154G, 2654G, 3154G and 3754G forestry excavator models were designed to handle unpredictable land and arm loggers with productive, durable and reliable machines feature excellent total fluid economy (diesel fuel and DEF). Additionally, the diesel particulate filter (DPF) cleaning occurs automatically, without disrupting machine productivity. Extensive engine testing resulted in the DPF being able to reach up to 15,000 hours before requiring ash removal. featured in the cab provides operators with transparency. This monitor shows real time values for every pressure, temperature and speed sensor on the machine. Transmission temperatures are constantly being monitored within the crawler dozers to avoid damage to the hydrostat system. Motor Graders John Deere motor graders keep the shoulder clear of any heavy debris HP and 205 HP respectively, the 750K and 850K crawler dozers are highly productive machines that offer increased uptime and lower daily operating costs. The 750K and 850K models The 750K and 850K models also excel in steep slope application by using innovative winch systems that assist with traction and increase machine stability 70 International Forest Industries | FEBRUARY / MARCH 2018 Crawler dozers can be incredibly helpful when accessing the timber stand. The combination of the FT4 engines, robust HP and optimal fluid economy ensure that when they are clearing obstacles, spreading ballast, and cutting paths for roads, productivity is top of mind. The 750K and 850K models also excel in steep slope application by using innovative winch systems that assist with traction and increase machine stability. These dozers use hydrostatic transmissions, a feature John Deere developed in crawler dozers in North America in 1976. The electronic control system provides customers with improved response and controllability, increasing productivity and boosting the operator experience. The LCD colour display monitor The John Deere 620G and 622G motor grader models feature ample torque and blade pull to excel in even the toughest terrain. With operating weights of up to 42,000 lbs and equipped with FT4 6.8 litre engines, the 620G and 622G models at 215 HP and 225 HP respectively, provide the powerful performance that customers expect from the G-Series line-up. Because of their levelling ability through the grading process, the 620G and 622G motor graders assist with accessing the tree stand by keeping the shoulder of the road properly levelled. With the support of their impressive horsepower, they can also be used to keep the shoulder clear of any heavy debris. A popular feature on the machines, the dual joystick provides operators with an intuitive control to the standard antler rack and minimizes hand movement during direction changes and gear shifting. This advancement improves control comfort by eliminating the need to ‘twist’ for blade circle or articulation movements. All John Deere motor graders come standard with Eco Mode, optimizing fuel usage. Eco Mode decreases operating costs by an extra five to 10 percent compared to the larger 670G and 672G motor grader models.
