A long-bogie version of the 1510G forwarder is available for logging on soft terrain. The distance between the front and rear wheel hubs in the rear bogie is 1890 mm, i.e. 390 mm longer than in the standard model.
The power train and turning radius are the same as with the standard HD portal bogie-equipped machine. The long-bogie solution is suitable for both normal and soft terrains. The long bogie brings stability when navigating over obstacles in rocky terrain, and the low ground pressure of the rear frame makes the machine an excellent choice for logging in soft terrain.
Adaptive driveline control is a unique standard feature in G-Series mid-size forwarders. 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 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.
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.

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.
The precision and power of the mid-sized G-Series forwarders’ boom control is unprecedented. New controllers, simplified CAN busses and streamlined electrical systems bring more power, speed and precision control to the boom.
The updates decrease malfunction sensitivity and accelerate troubleshooting. The number of fuses has been reduced thanks to controllers that recognize overcurrent situations and cut the feed when necessary to protect the equipment.
The optional intelligent boom control makes forwarder work easier and faster and it improves productivity. Boom control is precise, fast and easy because the operator can focus on controlling the grapple rather than the boom joint movements. 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.
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.
The new control modules replace the FlexController modules used in the E-Series; it simplifies the electrical system and brings added processing capacity. Forwarders have three 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.
