Patent number: 9045171Abstract: A work vehicle includes a fixed hood covering a rear area of an engine compartment housing an engine and an engine accessory, a swing axis extending through the rear area of the engine compartment in a transverse direction of the vehicle, and a swing hood swinging around the swing axis between a closed position and an open position. The swing hood tucks the fixed hood inside the swing hood and thus covers the fixed hood in the open position, and covers a front area and a middle area of the engine compartment and overlaps with a front end portion of the fixed hood in the closed position.Type: GrantFiled: March 1, 2013Date of Patent: June 2, 2015Assignee: KUBOTA CORPORATIONInventors: Kazuaki Nogami, Hiroyuki Tada, Yoshiyuki Esaki, Kazutomo Miyaguchi, Eiji Sato, Akira Minoura, Hironori Tsuchihashi, Osami Fujiwara, Seiya Yoshida

Patent number: 8991143Abstract: A work vehicle includes wheels and a mower unit that are driven by power from an engine, and a mower driving detecting section for detecting power transmission condition to the mower unit. An isochronous controlling section controls the engine in an isochronous control mode for maintaining an engine rotational speed at a predetermined fixed value, independently of an engine load. A droop controlling section controls the engine in a droop control mode for varying the engine rotational speed in dependence on the engine load. If power is transmitted to the mower unit, the isochronous control mode is selected.Type: GrantFiled: February 25, 2013Date of Patent: March 31, 2015Assignee: Kubota CorporationInventors: Osami Fujiwara, Hironori Tsuchihashi, Kazutomo Miyaguchi, Kazunari Tsujino, Yoshikazu Takemoto
