  • Patent number: 11140814
    Abstract: A work vehicle includes a detection signal processing section for processing detection signals from a group of sensors mounted on a vehicle body and outputting detection result data and a display unit for displaying the detection result data. The display unit includes a first displaying area for displaying time changing data included in the detection result data, the time changing data changing over time, a second displaying area for displaying safety data included in the detection result data, the safety data relating to safety confirmation, and a third displaying area for displaying alarm-relating data included in the detection result data.

  • Patent number: 10995722
    Abstract: A work vehicle includes an engine controller for driving an engine, a power supply line, a power supply control line, and a display signal line. When a check switch switchable into a safe position corresponding to safe drive of the engine and a non-safe position is switched to the safe position, the power supply control line renders a power supply relay ON. The display signal line transmits a signal indicative of the switched state of the check switch to a display.

  • Patent number: 10919421
    Abstract: A utility vehicle includes a cargo box and a seat device located on the front side of the cargo box. The seat device includes a seat bottom and a seat back that includes a first lateral swinging shaft that extends in a lateral direction, a seat back frame that swings about the first lateral swinging shaft between an upright position and a horizontal position at which the seat back frame overlaps with the seat bottom, and a seat back main body that is attached to the seat back frame. The seat back frame in the horizontal position defines an expansion floor by which the floor of the cargo box is expanded in a forward direction. The seat back main body swings to a hanging orientation with respect to the seat back frame in the horizontal position and is located in front of the seat bottom.

  • Patent number: 10208852
    Abstract: A steering lever system includes a pair of lever bodies, a pivotal body coupled to each of the lever bodies and a neutral position detector. The pivotal body includes a first boss portion and a second boss portion. The lever body is pivotable about a first pivot axis of the first boss portion from a neutral position to a neutral end position. The lever body is also pivotable about a second pivot axis of the second boss portion from a forward traveling end position through a neutral position to a reverse traveling end position. The neutral position detector is responsive to a detected portion provided in an auxiliary member fixed to the lever body, at the neutral end position of the lever body. The detected portion is offset from a pivotal locus of the lever body about the first pivot axis.
