A tractor in which a lift valve of a hydraulic system for lifting up/down a work machine is mechanically coupled to a lift lever, and conditions for an engine startup are set as follows: a reverser lever is at a neutral position thereof; a PTO (power take-off) clutch is disengaged; a seat switch is ON; and the lift lever is at a lowermost position thereof. A switch driving unit is provided on a side face of the lift lever so that the side face is orthogonal to a turning direction of the lift lever; a switch is provided so as to be opposed to the switch driving unit when the lift lever is turned to be at the lowermost position; and the lift lever at the lowermost position is detected by the switch.

Tractor

A tractor in which various main manipulation parts are arranged on the right side of a driver, to allow the manipulation parts and a steering wheel to be reliably grasped with different hands, thus improving workability for the driver; and the various main manipulation parts are arranged within a semi-arc range over which a right arm of the driver turns about his/her right elbow which rests on an arm rest, thus improving workability for the driver and relieving driver fatigue. The tractor includes an operation unit in which a loader manipulation part and a hydraulic manipulation part are arranged near a driver seat disposed at the rear of a steering wheel, the loader manipulation part and the hydraulic manipulation part being arranged within a semi-arc range over which a right arm of a driver turns about his/her right elbow which rests on a right arm rest of the driver seat.

An electronic device includes: a display section displaying function screens each including a plurality of function setting keys for receiving function settings; a first operation key for displaying the first function screen at the display section; a second operation key for displaying the second function screen at the display section; and a control section displaying, at the display section, the first and second function screens in accordance with operation performed on the first and second operation keys. The control section displays the first and second function screens at the display section when the first and second operation keys have been pressed simultaneously.
