  • Patent number: 10151081
    Abstract: Disclosed is a work vehicle adapted to mount a front work implement operated under a forward facing posture and a rear work implement operated under a reverse facing posture. A forward/reverse operational unit includes a first operational tool operable by one hand of a driver under the reverse facing posture and a second operational tool operable by the one hand engaged in operation of the first operational tool.
    Type: Grant
    Filed: May 25, 2016
    Date of Patent: December 11, 2018
    Assignee: Kubota Corporation
    Inventors: Yoshihiko Kuroshita, Masahiro Sugioka, Daisuke Hashimoto

  • Patent number: 9238899
    Abstract: 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 bucket 15 or a lowering restricted angle which is set greater by a set angle than a lowering limit angle of the bucket.

  • Patent number: 9238900
    Abstract: 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.
