Abstract: A work implement tilt control system for a tracked vehicle having a frame and a work implement mounted to the frame, the system comprising: a lifting unit configured to controllably raise or lower at least part of the work implement; an input device actionable by a first and second types of external actions associated with raising or lowering of the work implement; and a vehicle computer configured to send a signal to the lifting unit to carry out a lowering cycle of the work implement in case the vehicle computer determines that a set of conditions has been met. In some cases, the set of conditions includes: (i) a movement characteristic of the tracked vehicle exceeds a threshold; and (ii) the input device has been actioned by the first type of external action since carrying out the most recent lowering cycle of the work implement.

Abstract: A new tracked vehicle arrangement with a main vehicle and a trailer, where each of the main vehicle and the trailer have a track assembly on either side, and the tracks of the trailer are driven by the prime mover of the main vehicle. In the longitudinal direction of the main vehicle, only a small fraction (less than 25%) of the length of the main vehicle's cab, which is mounted above the frame, overlies the main vehicle's track assemblies, whereas the fuel tank is located between the cab and the prime mover. In a widthwise direction of the tracked vehicle, the fuel tank at least partly overlies the right and left track assemblies. This provides a counterbalance for the trailer, which has a platform attached by a first pivotable connection to the frame of the main vehicle and by a second pivotable connection to the frame of the trailer.
