A tractor, including: a link mechanism fixation-member which regulates rotation of the HST trunnion shaft by abutting the link mechanism; a link mechanism fixation-member operation lever which makes the link mechanism fixation-member about the link mechanism, or makes the link mechanism fixation-member move in a direction so as to get apart from the link mechanism; a brake pedal which is provided at the other side of the left-and-right sides of the step floor; and a link mechanism joining-cancellation mechanism which makes, in a case where the link mechanism fixation-member is abutting the link mechanism, the link mechanism fixation-member move in a direction so as to get apart from the link mechanism when stepping-on of the brake pedal is performed.

A hydraulic synchronizer selectively couples one or more gears to a drive shaft. The synchronizer has a shaft hub with a splined annulus and a fluid passage. A ring is disposed about the shaft hub and movable along a rotation axis of the shaft hub. A shift collar is fixedly coupled to the ring and has a splined annulus engaged with the splined annulus of the shaft hub. The shift collar is configured to engage splines of a gear when the ring is in an engaged axial position and to disengage the splines of the gear when the ring is in a neutral position. The shift collar transmits rotational input from the shaft hub to the gear when the ring is in the engaged axial position. Hydraulic chambers receive hydraulic fluid from the fluid passage and move the ring to the engaged and neutral positions.

A work machine includes a machine body, an engine, a rotary electrical device, and an electric power controller. The engine is provided on the machine body to move the machine body. The rotary electrical device is provided on the machine body to move the machine body. The electric power controller is disposed above the rotary electrical device in a height direction along a height of the work machine to control the rotary electrical device.

The invention proposes a method of supplying with hydraulic fluid a hydraulic motor (2) of a drive wheel supporting a vehicle by means of a cylinder-type suspension system (1). The hydraulic fluid passes through a feed duct (25) extending longitudinally through a cylinder (3) of the cylinder-type suspension system (1). The invention also relates to the use thereof in order to eliminate the need for hoses.

A work vehicle includes a body. The vehicle includes a panel configured to cover a portion of the body of the vehicle. The vehicle includes an operator station configured to be stowed within the body of the vehicle to enable the panel to cover the operator station while the vehicle is at least partially autonomously controlled. The operator station is configured to be deployed at least partially external to the body of the vehicle to enable an operator to control the vehicle.

An off-road vehicle includes an air intake system that comprises an opening that, in operation, receives air, and an exhaust system that includes an exhaust stack positioned in the opening of the air intake system.

A work vehicle is provided with a support member that supports an output shaft of a wheel differential mechanism between a differential case and a planetary reduction mechanism. The support member is configured to engage the output shaft relatively immovably in a direction along the axis of the output shaft.

A work vehicle includes a front and a rear opposite to the front in a front-rear direction of the work vehicle, and a lateral direction perpendicular to the front-rear direction. The work vehicle further includes an engine, a hood, a fuel tank, a fuel supply path, a separator, and a front protector. The hood is to cover the engine. The fuel tank is to store fuel. The fuel stored in the fuel tank is to be supplied to the engine via the fuel supply path. The separator is provided in the fuel supply path to remove water in the fuel flowing through the fuel supply path. The separator includes a protruding portion protruding from the hood in the lateral direction. The front protector is provided at a front side with respect to the protruding portion of the separator to protect a front portion of the protruding portion.

A transmission structure of the present invention causes, during a period from a time point when a rotational speed of a drive rotational power reaches a predetermined first/second speed stage shift-up start speed until a first/second speed stage shift-up end time point, one of an input-side clutch mechanism pair and an output-side clutch mechanism pair to be in a double transmitting state, and causes, in the double transmitting state, a first clutch mechanism and a second clutch mechanism of the other one of the input-side clutch mechanism pair and the output-side clutch mechanism pair to be shifted to a disengagement sate and an engagement state, respectively, while having frictional plate slid.

A heat exchanger system for an agricultural vehicle. The heat exchanger system has at least two separate heat exchanger assemblies, where an adjustable baffle is used to vary the airflow between the heat exchanger assemblies, accordingly varying the cooling effect of the assemblies, based on system requirements. The adjustable baffle may be arranged to restrict or block at least a portion of a heat exchanger to reduce airflow through the exchanger, to provide a flow bypass of an exchanger, and/or to proportionally adjust the airflow through a pair of heat exchangers provided as part of a single heat exchanger assembly.
