Abstract

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.

Claims4

Dependent claims

A tractor comprising:

a vehicle body frame;
an engine that is mounted on a front portion of the vehicle body frame;
a hood that houses the engine, the hood being configured to pivot up/down about a front pivot that is located on a front end of the vehicle body frame, between a closed position at which the hood covers the engine and an open position at which the hood exposes the engine;
an anti-vibration member that is provided between the engine and the vehicle body frame and supports 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 including an abutting-target portion against which the engine is configured to abut from a rear side, to prevent the engine from swinging forward in a front-rear direction of the vehicle body,
wherein
the anti-vibration member includes:
a first anti-vibration member that is attached by a first attaching member to a position that is forward and to the right of the engine;
and a second anti-vibration member that is attached by a second attaching member to a position that is forward and to the left of the engine,
the abutting-target portion includes:
a first abutting-target portion that is located forward and to the right of the engine;
and a second abutting-target portion that is located forward and to the left of the engine, and
the first attaching member is configured to abut against the first abutting-target portion from the rear side, and the second attaching member is configured to abut against the second abutting-target portion from the rear side.
