摘要： A protection system (200) for a work vehicle (100) includes a rear portion (275) configured to couple to a chassis (110) of the work vehicle and a top portion (250) configured to couple to a cab (120) of the work vehicle. The top portion is also configured so that at least part of the top portion is positioned above the cab of the work vehicle relative to a ground surface. In addition, a first height (251) of a maximum vertical extent of the top portion relative to the ground surface is substantially equal to a second height (352)of a maximum vertical extent of the rear portion relative to the ground surface. Further, the rear portion and the top portion are separated from one another while the rear portion is coupled to the chassis and the top portion is coupled to the cab.

摘要： A dual mode control system for a work vehicle includes a hydraulic system configured to drive a loader assembly and a dozer assembly coupled to the work vehicle. The hydraulic system includes a fluid delivery system comprising a plurality of flow paths fluidly coupled to a hydraulic pump. The hydraulic system includes a valve assembly configured to regulate diversion of fluid into a first and a second hydraulic cylinders coupled to the fluid delivery system to adjust the loader assembly, or into a third cylinder coupled to the fluid delivery system to adjust the dozer assembly. The dual mode control system also includes a controller operably coupled to the valve assembly, and one or more user interfaces coupled to the controller to enable an operator to provide inputs to cause the controller to adjust the valve assembly, and to thereby adjust the loader assembly or the dozer assembly.
