<strong>ROTTNE</strong> H-<strong>14</strong>THE ALLROUND HARVESTERRequirement specifications for the developmentwork on Rottne H-<strong>14</strong> emphasisedthat the harvester should be suitable forboth thinning and final felling and be ableto work with different sizes of head.The hydraulic system, which is loadsensing, has a large pump capacityand return fi<strong>lt</strong>ers submerged in the tank,which reduce the risk of air mixing inthe oil when using biodegradable oil.The a<strong>lt</strong>ernative heads for H-<strong>14</strong> haveidentical connections for both hydraulicsand measuring systems, making it quickand easy to switch heads.Rottne H-<strong>14</strong> therefore has a robust chassiswith a low centre of gravity. To ensuregood stability when felling on downhillslopes, the wheel base is adapted so thatthe rear provides a good counterweight.The loader, RK <strong>14</strong>0, is located directlyabove the portal bogie and features a ti<strong>lt</strong>function with ample forward/backwarddeflection.The reach for a standard machine is 10metres, but a different extension boom isavailable as an option, enabling reachesof 10 to 12 metres depending on the sizeof head being used.<strong>ROTTNE</strong> H-<strong>14</strong>
710/45x26,5<strong>ROTTNE</strong> D5 MACHINE CONTROL SYSTEMThe Rottne D5 machine control system, which is based on CAN bus technology, controls and monitors the engine,transmission and loader. D5 comprises a main computer, a 7” colour touch screen and a number of control unitsplaced out on the machine close to the functions to be controlled. The main computer communicates by means of aCAN bus cable linked to all the control units. The operator can adjust settings for the loader, transmission and engine,monitor pressure, temperatures and fluid levels and perform troubleshooting using the display (touch screen) onan adjustable arm slightly forward of the operator’s position. Alarms are indicated by visual and audible signals andare displayed in clear text on the display.<strong>ROTTNE</strong> D4 BUCKING SYSTEMRottne D4 is a well-tested and reliable bucking system consisting of various computer-based units, which areinterconnected via a CAN bus. The cab features a large, clear touch screen and a keyboard in front of the operator,as well as a printer integrated into the ceiling panel. The screen displays length and diameter as well asother information on the tree currently being processed in the head. The touch screen also enables settings tobe made and modified easily as well as generation of production reports, etc.Otherwise, data entry and price list changes are made using the keyboard. Communication is via USBmemory, e-mail or printer. Bucking is optimised with value or distribution bucking, but, as an a<strong>lt</strong>ernative,there is also a simpler program for priority bucking. Control and calculation computers as well as IO boxesand sensors are located on the head, and signal transfer to the cab is via CAN bus. The controlling of thehead and the processing are performed using keypads on the loader levers, located in lever panels onthe seat’s armrests. The operator can check and adjust settings for pressure, times and other functionson the head from the touch screen in the cab. A GPS receiver and map software as well as systems foroperations follow-up are available for D4.<strong>ROTTNE</strong> RK <strong>14</strong>0<strong>ROTTNE</strong>710/55x34710/45x26,521"525118"3000<strong>14</strong>4"min 3650157"4000307"7800472"12000<strong>14</strong>2"360059"1500 85"85"215021500165"4200InchmmRitn. nr. 32246
