The Deere right at home on steep slopes
TOUGH, STEEP slope applications test a machine and operator, and can have serious impacts on productivity. Understanding the challenges of this unique application, John Deere offers solutions ideal for logging on steep terrain. With tracked and wheeled machines each offering unique and different advantages to their applications, there is an equipment solution to fit nearly every operation.
M-Series Tracked Feller Bunchers and Harvesters
The John Deere M-Series Tracked Feller Bunchers and MH-Series Harvesters offer productive and durable machines that can power through tough terrain. The M-Series offers several models depending on Feller Buncher or Tracked Harvester, that all feature a best-in-class leveling system. The 859M/ MH gives operators a lowtail swing option, while the 909M and 959M/MH provide a larger tail swing option for larger timber applications.
All models incorporate a patented leveling control system that uses sensor technology to maximize the forward tilt angle (26 degrees forward), while electronically preventing any possible mechanical interference when also tilting to the side. The leveling envelope boundaries are set automatically and the patented system provides a smooth transition when approaching the leveling limits. This eliminates any sudden stops, further enhancing the stability of John Deere machines when used on slopes. This improves operator comfort so they can stay productive on the most challenging terrains.
Featuring the John Deere 9.0 L engine, the M-Series machines provide 330hp, ample power when combined with the robust undercarriage, which offers maximum stability and tractive effort ideal for steep terrain. A variety of boom sets, felling heads and harvesting attachments can be combined to optimize productivity across a range of conditions. And with thick plates and large pins and bushings, operators can rely on a sturdy boom that provides the reach and durability needed for tough steep slope applications.
The spacious cab features ergonomically designed configurable controls and 4-point safety belt to keep the operator secure and comfortable. Fully adjustable armrests provide fingertip control of all machine functions, and an air-conditioned seat provides exceptional daylong comfort in the climate-controlled cab. Floor-to-ceiling front and side windows, including exceptional vision to the right, plus an overhead skylight and floor glass provide an outstanding view of the cutting area and the tracks so the operator can avoid any pitfalls that may disrupt the balance of the machine.
G-Series Wheeled Harvesters and E Series Forwarders
For wheeled solutions, the John Deere Harvesters and Forwarders have led the industry for over two decades. With their patented balanced bogie system, these machines offer superior tractive effort and stability ideal for steep and uneven terrain. The 1270G EightWheel Harvesters provide additional traction and stability with eight-wheel drive offering excellent traction and stability that can navigate terrain that has typically been off-limits for mechanized logging.
The G-Series harvesters feature standard Processing Power Control (PPC), optimizing fuel efficiency of the John Deere 9.0 litre engines. The PPC system anticipates the engine load and responds with the right power increase, thus improving the fuel economy. Additionally, an advanced twin-pump hydraulic system ensures ample power for smooth, simultaneous operation and maximum control of the boom and harvester head. With the PPC, operators can ensure they maintain precise control of the boom and head, while providing ample power to climb and hold position on steep slopes – maximizing productivity.
The G-Series harvesters are equipped with the TimberMatic™ H-16 control system, providing increased processing capacity. The user-friendly system, control modules and wiring harnesses enhance machine performance and precision. The TimberMatic H-16 control system is a comprehensive package for basic machine control, measuring and bucking, allowing the operator to work faster and easier.
Another key feature of John Deere Wheeled Harvesters and Forwarders ideal for steep slopes is the redesigned leveling and rotating cab. Ergonomically designed seats, along with air conditioning and heating, reduce operator fatigue, providing consistent productivity throughout the day.
Across the world, the demand for traction assist systems is growing, and in many cases, being met with John Deere machines. German-based HAAS Maschinebau has developed a traction assist winch exclusively for John Deere wheeled harvesters and forwarders. This solution is being used in Europe, South America, and recently entered the North American market. A proven solution, these winches are installed on the front or rear of the machine, allowing customers to work above or below the extraction road and can also be fitted with an optional strawline winch to significantly simplify the job site set-up. The balanced bogie axles of the John Deere machine make it an ideal carrier for traction-assist solutions.
