Description

  The present invention relates to a tractor equipped with a front loader.

  Conventionally, as one form of the tractor, the prime mover part provided at the front part of the body frame is covered with a bonnet, and the bonnet is freely openable up and down with the lower part of the front end as a rotation fulcrum. There is one in which a base end portion of a front loader is attached and a bucket of the front loader can be moved up and down at a front position of a bonnet (for example, see Patent Document 1).

  A front guard body is disposed immediately in front of the front grill formed at the front of the bonnet so that the front guard body protects the headlights provided on the front grill. The front guard body is a front view gate from a pair of left and right extension pieces extending in the vertical direction at the front end portion of the body frame, and a left and right extension piece extending between the upper end portions of both the vertical extension pieces and extending in the left and right directions. It is formed into a mold.

  In this way, when loading the earth and sand on the truck bed with the front loader, even if the tractor is too close to the truck bed, the head guard etc. is protected by the front guard body. The headlight or the like can be prevented from being damaged.

  In addition, the front guard body pivotally supports the lower end of each vertically extending piece on the body frame so that the front guard body can be rotated in the front-rear direction, and between the upper part of each vertically extending piece and the side wall of the bonnet. The bonnet is linked with the up / down opening / closing operation of the bonnet and the front / rear rotation operation of the guard frame body through a connecting piece.

In this way, when the bonnet is opened, the front guard body rotates forward in conjunction with the bonnet so that the bonnet does not interfere with the front guard body.
