A front guard attached to a front portion of a vehicle body of a work vehicle includes a lower frame attached to the vehicle body, and an upper frame that is attached to the lower frame so as to be swingable around a shaft oriented in the vehicle width direction and the posture of which can be changed between a standing posture and a forward leaning posture by swinging with respect to the lower frame. The upper frame has: a left part that is pivotally supported by a left portion of the lower frame and extends upward; a right part that is pivotally supported by a right portion of the lower frame and extends upward; and an upper part that couples an upper portion of the left part and an upper portion of the right part. The upper part is provided with a protruding portion that protrudes downward.

Front guard and working vehicle

A front loader includes a working tool and an attachment body to which the working tool is attached, including a lock pin configured to attach and fix the working tool, a lock lever configured to move the lock pin between a releasing position and an attaching position, and a latching portion having a retaining mechanism configured to retain the lock lever at the releasing position and another mechanism configured to move the lock lever to the attaching position.

Front loader and working machine

A stand of a front loader includes: a main body that is disposed on a boom and swings between a supporting position in which the main body supports a front loader and a storage position in which the main body is stored; a grounding-member swing shaft that is disposed on the main body and engages with the boom to hold the main body in the storage position; a swinging member swingably disposed on the boom; and an engagement lever disposed on the swinging member, wherein the main body has a guiding hole that guides the engagement lever to regulate a swinging range of the main body.

When maintaining a ground pivot angle of the bucket constant irrespective of any vertical pivotal movement of the boom, a ground angle maintaining controlling section stops a bucket actuator when it is detected that a vertical pivot angle of the bucket has reached an elevation restricted angle which is set smaller by a set angle than an elevation limit angle of the bucketor a lowering restricted angle which is set greater by a set angle than a lowering limit angle of the bucket.

Front loader

The front loader includes a boom actuator configured to pivotally drive a boom along a vertical direction relative to a traveling vehicle body about a first pivot axis which is oriented along a right/left direction, a bucket actuator configured to pivotally drive a bucket along the vertical direction relative to the boom about a second pivot axis which is oriented along the right/left direction, a manual controlling section for controlling operations of the boom actuator and the bucket actuator based on a manual operation of an operational tool, a boom angle detector for detecting a vertical pivot angle of the boom, a bucket angle detector for detecting a vertical pivot angle of the bucket relative to the boom, a calculating section for calculating a ground pivot angle of the bucket based on an output from the boom angle detector and an output from the bucket angle detector.
