An information display system for a work vehicle includes a meter panel including a digital display and a controller configured or programmed to control operation of the meter panel. The work vehicle includes a DPF and a sensor to detect an accumulation amount of PM in the DPF. During DPF regeneration, the controller is configured or programmed to calculate progress of the DPF regeneration based on at least one of an output signal from the sensor or an elapsed time, and cause the digital display to display progress information indicating the calculated progress. When a predetermined condition is satisfied during display of the progress information, the controller is configured or programmed to stop displaying the progress information and instead cause the digital display to display a message relating to the DPF regeneration. When display of the message ends, the controller is configured or programmed to resume displaying the progress information.

The present invention includes an exterior cover (6), and two or more exterior components (7, 8) arranged in an up-down direction or in a direction intersecting the up-down direction and attached to the exterior cover (6) such that the two or more exterior components (7, 8) are visible externally. Two adjacent exterior components (7, 8) of the two or more exterior components (7, 8) include respective joint portions which overlap each other when viewed in a direction intersecting an outer surface of the exterior cover (6) and which are joined to each other.

A hydraulic circuit includes: a locking cylinder (22) capable of elongating and contracting to switch between a fixed state in which a bucket is fixed to a front loader and a released state in which fixing of the bucket to the front loader is canceled; a first locking oil passage (141) through which the hydraulic oil to be fed to the locking cylinder (22) flows to put the locking cylinder into the fixed state; a second locking oil passage (142) through which the hydraulic oil to be fed to the locking cylinder (22) flows to put the locking cylinder into the released state; and a connecting oil passage (160) that connects the first locking oil passage and the second locking oil passage, and has a throttle portion (161) capable of adjusting the flow rate of the hydraulic oil flowing between the first locking oil passage (141) and the second locking oil passage (142).

A work vehicle includes: a machine body (3) including left and right front wheels (1) and left and right rear travel devices (2); a hood (8) provided at a front portion of the machine body (3); an operator section (9) provided at a portion of the machine body (3) rearward of the hood (8); and left and right illumination units (51) provided at front portions of the hood (8), each of the left and right illumination units (51) including: a first illumination section (56) configured to illuminate a region (AL1, AR1) forward of the hood (8); and a second illumination section (57) configured to illuminate a region (AL2, AR2) rearward and downward of the region (AL1, AR1) illuminated by the first illumination section (56).

A work vehicle includes: a machine body (3) provided with a travel device (2); a hood (8) provided at a front portion of the machine body (3); an operator section (9) provided at a portion of the machine body (3) rearward of the hood (8), the operator section (9) having: a floor (12); and entry and exit sections (13) for boarding and deboarding the operator section (9), the entry and exit sections (13) being provided at left and right portions of the floor (12); and a battery (28) provided below a portion of the floor (12) corresponding to the left or right entry and exit section (13).

A work vehicle includes: a machine body (3) provided with a travel device (2); an engine (4) provided at a front portion of the machine body (3); a fuel tank (79); an operator section (9) provided at a portion of the machine body (3) rearward of the engine (4); a wall section (40) partitioning the engine (4) from the operator section (9); and a water separator (42) configured to separate and collect water from a fuel supplied from the fuel tank (79) to the engine (4), the water separator (42) being provided on a side where the operator section (9) is located relative to the wall section (40).

A working machine includes a machine body, a traveling device, an operating lever (21), and an operation sensor (40). The operating lever includes a lever portion (31), a support shaft portion (32) to rotate in a circumferential direction as the lever portion is pivoted, and a sensor bracket (37) to support the operation sensor. The operation sensor includes a magnet (41), and a switch (42) to be switched between an ON state and an OFF state in response to the magnet approaching or moving away from a predetermined detection position. The machine body includes a sensor mount frame (2F) to support the sensor bracket. The sensor bracket includes a first bracket (37A) attached to an outer periphery of the support shaft portion to support the magnet, a second bracket (37B) to attach the switch thereto, and a third bracket (37C) to connect the second bracket to the sensor mount frame and support the switch at a position where the switch is allowed to detect the magnet at or in a vicinity of the detection position. The second bracket is connected to the third bracket such that the second bracket is allowed to change a position thereof in a direction along which the second bracket approaches and moves away from the magnet.
