Patent number: 9238899Abstract: 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.Type: GrantFiled: March 17, 2015Date of Patent: January 19, 2016Assignee: KUBOTA CORPORATIONInventors: Atsushi Matsumoto, Ryuichi Nadaoka, Masahiro Sugioka
