Patent number: 9416701Abstract: An exhaust gas purifying device is disposed in a portion of a motor section rearwardly of a vehicle body. A cylindrical mixing exhaust pipe is provided in a distal end portion of an exhaust pipe, through which exhaust gas discharged from the exhaust gas purifying device flows. The mixing exhaust pipe has a larger diameter than the exhaust pipe to overlap the exhaust pipe in a radial direction for drawing ambient air by the exhaust gas discharged from the exhaust pipe and mixing drawn air with the exhaust gas to discharge the mixed gas to the outside from a discharge opening. The mixing exhaust pipe is arranged in a lower side position of the motor section on one side of the vehicle width direction with the exhaust gas being discharged toward the front of the vehicle body.Type: GrantFiled: July 25, 2012Date of Patent: August 16, 2016Assignee: Kubota CorporationInventors: Isamu Morimoto, Akiyoshi Ono, Issei Tanimura, Hisashi Tsukatani, Mamoru Kawaguchi

Patent number: 8997786Abstract: Disclosed is a work vehicle having a hydraulic apparatus which can reliably prevent erroneous operation of the valve of the hydraulic apparatus even when the operating lever is moved inadvertently. With this hydraulic apparatus, with operations of a single operating lever in two directions, two valves are operated respectively. Two valve operating links for operating the two valves respectively are pivotally supported to a support shaft provided to a pair of frame plates and a lock pin is provided to the frame plates. The two valve operating links form pin holes. When the two valves are at the neutral positions, the lock pin is inserted into the pin holes with a locking operation of a lock operating tool, thus fixing the valve operating links and locking the valves.Type: GrantFiled: March 27, 2013Date of Patent: April 7, 2015Assignee: Kubota CorporationInventor: Hisashi Tsukatani
