A work vehicle and energy storage device include an electric machine having a stator and a rotor. The rotor is configured to rotate from the flow of electrical current provided to the electric machine, rotate to store energy of the work vehicle, provide a rotor mass to an end of the work vehicle, and generate electrical current for the work vehicle from rotation of the rotor. The rotor mass is greater than a stator mass.

A hood of a tractor including a front grill, a light unit, and an upper cover is provided with a center pillar. The front grill is attached to the center pillar, the light unit is attached to the front grill, and the upper cover is supported by the center pillar. The hood is further provided with a side frame and a lower cover, where the side frame is attached to the center pillar, and the lower cover is attached to at least the upper cover and the side frame.

An agricultural machine transmission has a powershiftable main group arranged upstream or downstream of a powershiftable split group in the direction of force transfer. The split group has an input shaft, an output shaft, and powershift elements, which when selectively actuated permit configurations of at least six different forward gears and at least three different reverse gears between the input shaft and the output shaft of the split group. A driveshaft of the main group is connectable by a first powershift clutch to a first input shaft and is connectable by a second powershift clutch to a second input shaft of the main group. Spur gear stages of the main group can be integrated into the force transfer path by actuating an associated shift element, coupling an associated input shaft to the drive shaft of the main group by configuring a respective gear of the main group.

A tractor includes: a vehicle body; an engine disposed in an engine compartment; a radiator that is disposed, in the engine compartment, further toward a vehicle-body front side than the engine and cools the engine; an exhaust-gas cleaning device that purifies exhaust gas exhausted from the engine using a reducing agent; a reducing-agent tank that stores the reducing agent supplied to the exhaust-gas cleaning device; and a battery, the reducing-agent tank being disposed, in the engine compartment, side-by-side with the battery and further toward the vehicle-body front side than the radiator.

A work vehicle includes a hydrostatic stepless speed changer device configured to speed-change driving power of an engine steplessly, a plurality of planetary gear speed changer devices configured to speed-change the driving power speed-changed by the stepless speed changer device, a plurality of clutch mechanisms corresponding to the plurality of planetary gear speed changer devices in order to take off the driving powers from these plurality of planetary gear speed changer devices individually, and a traveling speed changer device for speed-changing and transmitting the driving powers transmitted from the plurality of clutch mechanisms to a traveling mechanism. The plurality of planetary gear speed changer devices the plurality of clutch mechanisms and the traveling speed changer device are accommodated in a transmission case.

Provided is a fuel tank of a work vehicle in which fuel can be easily sucked into an engine. The fuel tank includes: a drain port which is open to an outside on a side surface and through which fuel is discharged to the outside; a suction port which is open to the outside on a side surface and has a center positioned lower than a center of the drain port and through which the fuel is sucked by an engine; and a first recess which is formed to be recessed downward with respect to a bottom surface and communicates with the drain port.

A method of operating an agricultural vehicle including a range gearbox, an independent PTO system driven from an auxiliary drive shaft and a ground speed PTO system driven from an output shaft of the range gearbox. The method includes transferring torque from the auxiliary drive shaft to the output shaft of the range gear box via the independent PTO system and the ground speed PTO system while drive to the range gearbox is interrupted during a change in the range gear.

In a transmission structure according to this invention, speed change ratios of input side first and second transmission mechanisms are set so that the rotational speed of a planetary second element is the same when an HST output is set to a second HST speed in either a first transmission state or a second transmission state, and the rotational speed of a planetary first element is the same when the HST output is set to the second HST speed in either the second transmission state or the first transmission state. The speed change ratios of an output side first and second transmission mechanisms are set so that the rotational speed developed in a speed change output shaft when the HST output is set to the second HST speed is the same in either the first or second transmission states.

A tractor includes: a vehicle body; an engine bonnet forming an engine compartment; an engine; a first exhaust-gas cleaning device that purifies an exhaust gas and is above the engine such that its long side is substantially parallel to a vehicle-body lateral width direction; a second exhaust-gas cleaning device that purifies the exhaust gas and is behind the engine such that its long side is substantially parallel to the lateral width direction; a vehicle body frame; and a supporting tool that is supported by the vehicle body frame, supports the first and second exhaust-gas cleaning devices, and includes a support column that extends upward from the vehicle body frame along a front portion of the second exhaust-gas cleaning device, and a support arm that extends forward from an upper portion of the support column along a lower portion of the first exhaust-gas cleaning device.
