A tracked vehicle, controller for the tracked vehicle, and a method performed thereon are provided that enable the pilot to steer the tracked vehicle using an existing joystick of the tracked vehicle.

A work vehicle that includes a hydraulic system. The hydraulic system includes a hydraulic motor that generates rotational power for one or more wheels on the work vehicle. A hydraulic pump couples to the hydraulic motor. The hydraulic pump pumps hydraulic fluid to the hydraulic motor. A hydraulic shift control system controls shifting of the hydraulic system. The hydraulic shift control system includes a controller that controls a hydraulic motor volume of the hydraulic motor and a fluid volume pumped by the hydraulic pump to gradually change a speed of the work vehicle during a shift.

A dual fuel tank system for a machine having a frame and an engine enclosure mounted on a rear portion of the frame includes a pair of support plates located at the rear portion of the frame and welded onto a pair of sides of the frame. Further, the dual fuel system also includes a pair of upper and lower support brackets secured onto each side of the engine enclosure. Furthermore, the dual fuel system also includes a pair of fuel tanks disposed on the pair of sides of the engine enclosure. Each fuel tank is releasably secured onto the support plate and an associated pair of the upper and lower support brackets.

A method, system, and machine for controlling the output of an engine of a machine includes calculating the difference between a measured track slip based on track speed and ground speed and a calculated target track slip depending on track speed and chassis pitch, inputting the difference into a controller to determine a propulsion engine torque limit, and limiting the engine toque to the propulsion engine torque limit plus a steering system input torque.

A tracked vehicle includes a pilot control module which enables the pilot to steer the tracked vehicle using an existing joystick of the tracked vehicle. The tracked vehicle also includes a dual track drive pedal which drives the tracks of the vehicle simultaneously. The joystick is used to make steering corrections when utilizing the dual track drive pedal.

A working machine includes a machine body, a prime mover, a traveling device mounted on the machine body, a traveling motor to provide a power to the traveling device and to switch between a first speed and a second speed higher than the first speed, a traveling pump to be driven by the prime mover and to supply operation fluid to the traveling motor, and a controller device including an automatic shifter to automatically shift the traveling motor to the first speed or to the second speed, a timer to count an elapsed time from the automatically shifting, and a shift prohibitor to prohibit the automatically shifting by the automatic shifter when the elapsed time counted by the timer is less than a threshold.

A tracked all-terrain vehicle is shown which includes an internal combustion engine, an electric generator, and a plurality of electric motors which drive movement of the tracks of the tracked all-terrain vehicle.

A tracked vehicle includes a pilot control module which enables the pilot to steer the tracked vehicle using an existing joystick of the tracked vehicle. The tracked vehicle also includes a dual track drive pedal which drives the tracks of the vehicle simultaneously. The joystick is used to make steering corrections when utilizing the dual track drive pedal.

A working machine includes a first traveling fluid passage connected to a first pressure-receiving portion, a second traveling fluid passage connected to a second pressure-receiving portion, a third traveling fluid passage connected to a third pressure-receiving portion, a fourth traveling fluid passage fluidly connected to a fourth pressure-receiving portion, and a connection fluid passage connecting at least two of the first, second, third and fourth pressure-receiving portions to each other. When a traveling operation member is operated, operation fluid flows to the first pressure receiving portion through the first traveling fluid passage, to the second pressure receiving portion through the second traveling fluid passage, to the third pressure receiving portion through the third traveling fluid passage, and to the fourth pressure receiving portion through the fourth traveling fluid passage.
