  • Publication number: 20240401695
    Abstract: A work vehicle includes a transmission to shift gears by switching between main transmission gears and auxiliary transmission gears, an input interface for a user to set a value of the main transmission gear corresponding to at least one of the auxiliary transmission gears, a storage to store a correspondence between the auxiliary transmission gear and the value, and a controller configured or programmed to, when the auxiliary transmission gear is switched, set the main transmission gear to the value corresponding to the switched auxiliary transmission gear based on the correspondence.

  • Publication number: 20240306526
    Abstract: A working machine includes a driver including a hydraulic actuator and a driven structure to be raised/lowered by the hydraulic actuator, a control valve to control the hydraulic actuator, and a controller configured or programmed to control the control valve to move the driven structure to a target position. The controller is configured or programmed to switch between (i) a first mode in which the controller controls the control valve by performing a first control based on a target flow rate of hydraulic fluid to actuate the hydraulic actuator and a deviation of an actual position of the driven structure from a target value and (ii) a second mode in which the controller controls the control valve by performing a second control including controlling the target flow rate to be lower than the first control when the deviation is more than zero and less than a predetermined deviation.

  • Publication number: 20240301662
    Abstract: A working machine includes a driver including a hydraulic actuator to be actuated by a hydraulic fluid, and a controller configured or programmed to change a drive speed of the driver in a drive start period. The controller is configured or programmed to, if a limit value based on which operation of the driver is limited is equal to or more than a threshold, perform a first control in which the controller changes the drive speed of the driver in the drive start period based on the limit value, and if the limit value is less than the threshold, perform a second control in addition to the first control, the second control being a control in which the controller changes a maximum flow rate of the hydraulic fluid to actuate the hydraulic actuator based on the limit value.

  • Patent number: 11859678
    Abstract: A working vehicle includes: a clutch displaceable to a connected state in which power is transmitted to a drive, a disconnected state in which the transmission is disconnected, and a half-clutch state in which power is slidably and partly transmitted to the drive; a detector that detects an operation position of a clutch pedal and outputs a detected value corresponding to the operation position detected; a control device that brings the clutch into the half-clutch state if the detected value corresponds with a threshold, and brings the clutch into the disconnected state if the detected value is less than the threshold and into the connected state if the detected value is greater than the threshold, and vice versa; and a change unit that changes the threshold to a different value in accordance with an operation on the operation member.
