An engine control device for a work vehicle, comprising: a front device non-engagement decision-making unit that makes a decision as to whether or not a front device is in an unengaged state; a steering device non-engagement decision-making unit that makes a decision as to whether or not a steering device is in an unengaged state; a pedal non-operation state decision-making unit that makes a decision as to whether or not an accelerator pedal is in a non-operation state; a neutral state decision-making unit that makes a decision as to whether or not a transmission is in a neutral state; a parking brake engagement decision-making unit that makes a decision as to whether or not a parking brake device is in an engaged state; a service brake non-engagement decision-making unit that makes a decision as to whether or not a service brake device is in an unengaged state; a condition decision-making unit that decides that an idling stop condition has been established when the front device is in the unengaged state, the steering device is in the unengaged state, the accelerator pedal is in the non-operation state, either the transmission is in the neutral state or the parking brake device is in the engaged state or the transmission is in the neutral state and also the parking brake device is in the engaged state, and the service brake device is in the unengaged state; a time count unit that starts a time count when the condition decision-making unit has decided that the idling stop condition is established and continues the time count while the idling stop condition is in effect; a time passage decision-making unit that makes a decision as to whether or not the time count at the time count unit exceeds a predetermined length of time; and an engine automatic stop control unit that stops an engine when the time passage decision-making unit decides that the time count at the time count unit exceeds the predetermined length of time, a selector member that excludes a state of engagement of the parking brake device from criteria for the idling stop condition. a front device non-engagement decision-making unit that makes a decision as to whether or not a front device is in an unengaged state; a steering device non-engagement decision-making unit that makes a decision as to whether or not a steering device is in an unengaged state; a pedal non-operation state decision-making unit that makes a decision as to whether or not an accelerator pedal is in a non-operation state; a neutral state decision-making unit that makes a decision as to whether or not a transmission is in a neutral state; a parking brake engagement decision-making unit that makes a decision as to whether or not a parking brake device is in an engaged state; a service brake non-engagement decision-making unit that makes a decision as to whether or not a service brake device is in an unengaged state; a condition decision-making unit that decides that an idling stop condition has been established when the front device is in the unengaged state, the steering device is in the unengaged state, the accelerator pedal is in the non-operation state, either the transmission is in the neutral state or the parking brake device is in the engaged state or the transmission is in the neutral state and also the parking brake device is in the engaged state, and the service brake device is in the unengaged state; a time count unit that starts a time count when the condition decision-making unit has decided that the idling stop condition is established and continues the time count while the idling stop condition is in effect; a time passage decision-making unit that makes a decision as to whether or not the time count at the time count unit exceeds a predetermined length of time; and an engine automatic stop control unit that stops an engine when the time passage decision-making unit decides that the time count at the time count unit exceeds the predetermined length of time, a selector member that excludes a state of engagement of the parking brake device from criteria for the idling stop condition.
