1910G Forwarders

The IBC (Intelligent Boom Control) option is a milestone in forest machine technology. The boom is accurate and easy to operate: the operator controls the boom tip directly instead of controlling independent boom joint movements. The system also considerably reduces  the number of tuning parameters needed and increases durability of boom structures and hydraulic cylinders.

Boom functions as one
The IBC system enables you to control the entire loader as one unit and you no longer need to learn to control several different boom movements together. Controlling the grapple is similar to controlling the movements of your own hand. The IBC system guides the boom wherever the operator wants to take the grapple. The system has predefined limit values and it adjusts boom operations within these limits according to need. In the latest 2.0 version of intelligent boom control, the precision of the grapple control has been improved, especially in long reaches. The software uses information about the grapple position, and the speed of the rotation in long reaches matches that of short reaches.

IBC system also has a separate,  preprogrammed option for unloading, where the strong jib and main boom movements are used more.

Electrical cylinder end damping
The IBC system also features electrical end damping for all the main boom movement directions. The system dampens the cylinder end movements softly and stops strong blow-like loads in the end positions which makes driving smoother and also improves the durability of the boom.

Operator adjustments
Operators can adjust the overall speed of the IBC system according to their needs. They can also adjust the speed between various boom parts or change it by using the extension boom manually during operation. The system is switched on and off with the press of a button.

Adaptive driveline control is a unique standard feature in G-Series machines. This control system improves the machines’ drivability and productivity. The operator selects the desired driving mode (Eco, Normal, Power) for the operating conditions, and the system automatically adjusts the engine’s RPMs to correspond with the engine load and keeps the driving speed steady also during high loads. The driveline control ensures that the diesel engine runs smoothly and uses the available maximum tractive force efficiently during high-load situations. Also the response of the drive pedal and frame steering have been improved with smart electronic filtering.

The cross-sectional area of the 1910G load space is 6.5 m² at its widest. The cross-sectional area of the narrow load space is 5.3 m². The new-generation headboard provides good visibility to the load space, facilitating the unloading process in particular.

In addition to narrow and wide load space, Variable Load Space (VLS) is optional. The variable VLS load space consists of 4 telescopic bunks and a headboard. The bunks can be extended and contracted hydraulically and the headboard expands automatically with the bunks. The headboard can also be expanded horizontally and vertically independent of the bunks. The load space width can be adjusted between 3,0 to 3,6 m and the cross-sectional area between 5,4 to 6,8 m². VLS load space option is available for both load space lengths, short and long.

Cabin comfort is a productivity factor. The cabin of a John Deere forest machine is a comfortable and ergonomic work environment. The cabin is available as fixed or rotating and levelling version.

The levelling and rotating cabin helps the operator to maintain the correct working posture to prevent stress on the back and shoulder areas. The operator can sit upright even on uneven terrain, and the cabin can be rotated in all directions to face the work area.  The cabin has more legroom in front and the seat has two different height settings. The proven and efficient vibration absorption improves the working conditions further. Leveling and rotating functions are an option in harvesters. The cabin is fixed if these options are not chosen.

Fixed cabin for forwarders is a completely different structure. One advantage of the fixed cabin for forwarders is the low centre of gravity, which provides a steady feel to the seat. The big windows offer good visibility in every direction and also close to the machine and its tires. The cabin has rubber mountings that dampen vibration. The noise level in the fixed cabin for forwarders is low and matches that of the leveling and rotating cabin.

For meal breaks, the cabins feature a mini oven and refrigerator.

The cabin’s interior materials were chosen with ease of cleaning in mind. The leather-like material on the interior pillars is easy to clean. The neoprene wiper blades are more durable than natural rubber blades.

The ergonomic seat, air conditioning and heating, sun visors and sun blinds, and side widow wipers add to cabin comfort.  Plenty of light is needed during dark hours, so the positioning of the lights has been continuously improved to enhance visibility during the autumn and winter.

The TimberMatic control system and user interface on G-Series forwarders have been further developed and improved to maintain the forest machine’s operational reliability. The TimberMatic features a configurable user interface, cruise control and inclination display. The new software version enables Remote Display Access (RDA) via the Internet (either MTG or other modem). RDA enables faster troubleshooting by servicing people and thus improves the machine’s uptime.

Forwarders have three control modules: for the cabin, the front frame and the rear frame. TimberMatic’s troubleshooting diagnostics are more detailed and illustrative.  The CAN bus increases reliability of the electrical system: simple, fewer connections, a dedicated bus for the engine and the base machine.

TimberMatic Maps is standard in all new John Deere forest machines. Based on the real time data from Maps to TimberManager, distributed through a cloud service, the contractor can follow up forest machine’s production and remaining work on the site and plan the operations further.

Hydrostatic pump and motor for transmission

The hydraulic components of the transmission in the John Deere 1910G forwarder are bigger than in previous models, so the average pressure level remains lower and the components have a longer lifetime. The number of pistons was increased from 7 to 9, further improving the machine’s performance in extreme terrain conditions. The more robust components of the pump, the engine and the bearings bring increased durability and reliability.

Boosting hydraulic efficiency also results in less fuel consumption. System reliability has been improved by reducing the number of sealing points.

Together with the engine’s wider torque area, the revamped transmission improves the forwarder’s driving performance, drivability and fuel economy.

John Deere Final Tier 4 engines meet the required emissions regulations while also bringing more power and torque.  The output of the John Deere 6090 PowerTech Plus engine in 1910G forwarder (200 kW) is 7.5% and torque (1315 Nm) even 21% more than in the T3 engine in 1910E.

Especially the low rpm ranges have much more torque than the E-models. The John Deere FT4 engine has the most torque in its class and a wide rpm range. The engine’s rpm remain steady during big and rapid changes in the load.
Even with the increased power, John Deere’s FT4 engine is very fuel efficient.

The FT4 engine and the entire fuel line can use 20% biodiesel.
