摘要： A tractor includes an engine that is mounted on a vehicle body frame, a hood that houses the engine and is configured to pivot about a front pivot in a top-bottom direction between a closed position at which the hood covers the engine, and an open position at which the hood exposes the engine, a mounting rubber that is provided between the engine and the vehicle body frame to support the engine in an anti-vibration manner, and a hood stay that supports the hood such that the hood is pivotable up/down about the front pivot. The hood stay includes an abutting-target portion against which the engine can abut from a rear side, to prevent the engine from swinging forward in a front-rear direction of the vehicle body.
