发明名称 Work vehicle
摘要 Systems and methods are disclosed for improving operability of a work vehicle. In accordance with one implementation, a work vehicle is disclosed. The work vehicle includes a first PTO shaft and a second PTO shaft, the first and second PTO shafts being removably mounted to a vehicle body rear structure and fitted to a power receiving unit on an implement side. The work vehicle also includes a PTO drive mechanism comprising a PTO transmission mechanism, the PTO drive mechanism transmitting rotational power from a power source to the first PTO shaft, and a storage unit storing the second PTO shaft. The work vehicle further includes a PTO transmission operation lever allowing a transmission operation to be performed on the PTO transmission mechanism, wherein the PTO transmission operation lever and the storage unit are provided in the vehicle body rear structure.

主权项 1. A work vehicle comprising: a first PTO shaft and a second PTO shaft, the first and second PTO shafts being removably mounted to a vehicle body rear structure and fitted to a power receiving unit on an implement side; a PTO drive mechanism comprising a PTO transmission mechanism, the PTO drive mechanism transmitting rotational power from a power source to the first PTO shaft; a storage unit storing the second PTO shaft; a PTO transmission operation lever allowing a transmission operation to be performed on the PTO transmission mechanism, wherein the PTO transmission operation lever and the storage unit are provided in the vehicle body rear structure; wherein when the transmission operation is performed, the PTO transmission operation lever can be moved in tandem with a rod unit extended along an axis of the transmission operation; and a transmission range varying mechanism that, when the first PTO shaft is being used, defines a transmission range for the PTO transmission mechanism based on the second PTO shaft, wherein the transmission range varying mechanism comprises: a fixed abutment unit provided on the rod unit,a movable abutment unit being pivotable between an abutment position in which the movable abutment unit can abut the fixed abutment unit, and a non-abutment position in which the movable abutment unit is positioned away from the abutment position, anda cam mechanism that biases the movable abutment unit toward the abutment position and pivots the movable abutment unit from the abutment position to the non-abutment position when an end of one of the first and second PTO shafts comes into contact with a movable projection unit projected into the storage unit; and the movable abutment unit being positioned at the abutment position and the movable abutment unit abutting the fixed abutment unit causes the transmission operation performed by the PTO transmission operation level to be restricted, and restricts the transmission range of the PTO transmission mechanism.
