    Abstract: A work vehicle includes a vehicle frame, a radiator, an engine, a first post-treatment apparatus, a second post-treatment apparatus, and a bracket. The engine is provided in front of the radiator. The first post-treatment apparatus and the second post-treatment apparatus are positioned in front of the radiator and treat exhaust from the engine. The bracket is positioned in front of the radiator and is elastically supported by the vehicle frame. The bracket supports the engine, the first post-treatment apparatus, and the second post-treatment apparatus. Both the highest position of the first post-treatment apparatus and the highest position of the second post-treatment apparatus are no higher than the highest position of the radiator.

    Abstract: A work vehicle includes a cab, a driver's seat disposed inside the cab, a first steering device, a second steering device, a seating sensor, and a control unit. The first steering device is disposed in front of the driver's seat. The first steering device is configured to perform a steering operation of the vehicle. The second steering device is disposed to a side of the driver's seat. The second steering device is configured to perform a steering operation of the vehicle. The seating sensor detects whether or not an operator is sitting in the driver's seat. The control unit disables the steering operation with the second steering device when the seating sensor detects that the operator is not sitting in the driver's seat.

    Abstract: A work vehicle includes an operation apparatus, a transmission having a plurality of gear positions, and a controller configured to control shift of a gear position of the transmission to a gear position equal to or lower than a shift upper limit position based on a vehicle speed of the work vehicle. The controller makes setting to raise the shift upper limit position by one position based on a first operation having been performed onto the operation apparatus. The controller changes the shift upper limit position from a first shift upper limit position immediately before a second operation different from the first operation to a second shift upper limit position based on the second operation having been performed onto the operation apparatus. The second shift upper limit position is higher than the first shift upper limit position by at least two positions.
