John Deere harvester heads are known for their productivity, reliability and especially accuracy. Both H400 and H200 series harvester heads have efficient feeding and delimbing.
The CH9 boom's slewing cylinders have been positioned parallel to the harvester's frame, thus improving the hosing and cabling. This also brings better forward visibility and minimizes wear and tear. The boom's path and speed is excellent, and the boom works effortlessly also when fully extended.
TimberMatic Maps registers the harvester's route and felled assortments with the exact location of each log. The forwarders working at the same site are seeing an accurate, real time situation and the harvester operator also sees the location of the forwarders. The operators can mark avoidable or difficult areas on the map, or any other notes from the terrain. The communication between the operators will improve as the data is stored in the system and is not dependent on a person's memory. The data between the machines are updated through a cloud service.
TimberMatic Maps is a standard feature in new John Deere forest machines and it is available with an upgrade kit to older models. The application requires 4G MTG and HPC15 (XL4) computer.
Intelligent Boom Control (IBC) is a unique boom control system. It is not an automatically operating extension of the boom or dampened valves, it is an intelligent control system that detects the positioning of the harvester head and adjusts the boom’s trajectories in one easily controlled motion.
IBC is designed to suit the machine’s work cycle. The trajectory and function of the boom automatically adjust as the boom is taken to a tree and when the tree is in the grapple. The operator doesn’t have to move the different sections of the boom individually. The electronic end dampening makes the work process pleasant and smoother, and reduces stress on the entire boom.
IBC improves work ergonomics and guides the operator in the correct use of the boom, which is directly reflected in the increased productivity of the machine. IBC brings significant benefits also in final fellings, as fewer movements are performed.
Adaptive Driveline Control is a software based control system which improves drivability and boosts productivity of John Deere G-Series forest machines. The system adjusts engine RPM's automatically based on engine load within driving RPM range. The minimum and maximum ranges are set in TimberMatic. The system provides high and stable engine RPMs during high engine load improving the utilization of engine power during simultaneous driving and boom usage. High engine RPM's are used only when needed, decreasing noise level and fuel consumption.
Engine power management prioritizes work pump over drive pump: engine RPM’s and the hydraulic power delivered to harvester head is maintained during simultaneous tree processing and driving.
While processing a tree, the system adjusts engine RPM's based on the processing power control settings. Adaptive Driveline Control is a unique standard feature only available from John Deere.
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.
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 for John Deere G-Series harvesters includes everything needed for base machine control and monitoring, measuring and bucking in one configurable user interface. The use of just one system makes the operator’s work faster and easier.
Several pressure sensors have been added to TimberMatic, making it possible to adjust most settings from inside the cabin – and even without tools. The pressure sensors make machine adjustments and condition monitoring easier via the machine’s on-board PC:
Additionally, the new software version enables Remote Display Access (RDA) via Internet (either MTG or other modem). RDA means faster troubleshooting by maintenance people and thus improved uptime for the machine.
The new control modules simplify the electrical system and bring added processing capacity. TimberMatic’s troubleshooting diagnostics have been improved. The new troubleshooting diagnostics of TimberMatic speed up the fault localization significantly. With the new MECA controllers, it is now possible to see the exact location of the fault in the CAN-bus and the repair is quick and easy.
In the TimberMatic display, an error icon comes up and when clicking the icon, you see the CAN-bus showing the fault location. Moreover, the system shuts the output to the sensor or actuator, if it detects overload or short circuit, and the machine can go on working. This improves the uptime quite considerably.
The double 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.
John Deere 1270G and 1470G harvesters are equipped with an advanced twin-pump hydraulic system. The two open-loop hydraulic pumps operate in tandem to produce the necessary hydraulic power. With the twin-pump system, there is enough power to simultaneously operate the boom and the harvester head. It maximizes boom control, ensures sufficient grip on the trunk, and increases productivity and operating comfort.
The Processing Power Control (PPC) system in the 1270G and 1470G harvesters has three different power levels to choose from so that the most suitable level can be selected for the work based on the size of the trees. The PPC system anticipates the engine load and responds with the right power increase for the situation. The Processing Power Control system improves the fuel economy of the harvester.
