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.

First claim

What is claimed is:

1. 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.

2. 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 vehicle body frame includes: a first main frame that is located on a right side of the engine and extends in the front-rear direction of the vehicle body; and a second main frame that is located on a left side of the engine and extends in the front-rear direction of the vehicle body,
the hood stay includes: a first hood stay that is provided on a surface of the first main frame inside the vehicle body; and a second hood stay that is provided on a surface of the second main frame inside the vehicle body,
the abutting-target portion includes: a first abutting-target portion that is located on a rear end of the first hood stay; and a second abutting-target portion that is located on a rear end of the second hood stay,
a first engine supporting frame that supports a right portion of the engine extends in the front-rear direction of the vehicle body inside the first main frame relative to the vehicle body, and a second engine supporting frame that supports a left portion of the engine extends in the front-rear direction of the vehicle body inside the second main frame relative to the vehicle body,
the anti-vibration member includes: a first anti-vibration member that is attached to a position between a front end of the first engine supporting frame and the first main frame by a first attaching member; and a second anti-vibration member that is attached to a position between a front end of the second engine supporting frame and the second main frame by a second attaching member, 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.

3. 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 vehicle body frame includes: a first main frame that is located on a right side of the engine and extends in the front-rear direction of the vehicle body; and a second main frame that is located on a left side of the engine and extends in the front-rear direction of the vehicle body,
a first engine supporting frame that supports a right portion of the engine extends in the front-rear direction of the vehicle body inside the first main frame relative to the vehicle body, and a second engine supporting frame that supports a left portion of the engine extends in the front-rear direction of the vehicle body inside the second main frame relative to the vehicle body,
a first lateral-swing stopper member for the engine is provided on and protrudes from a surface of the first engine supporting frame on the first main frame side, with a first lateral gap between the first lateral-swing stopper member and the first main frame, and
a second lateral-swing stopper member for the engine is provided on and protrudes from a surface of the second engine supporting frame on the second main frame side, with a second lateral gap between the second lateral-swing stopper member and the second main frame.

4. 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;
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; and
a flywheel that is attached to a front end of the engine,
wherein
the hood stay includes: a first hood stay that is located forward and to the right of the engine; and a second hood stay that is located forward and to the left of the engine, and
a cover that covers the flywheel from a front side extends between the first hood stay and the second hood stay.
