Mid-mount mower with power transmission coupling

A mid-mount mower having a mower unit mounted under a vehicle body between front wheels and rear wheels, the mower comprising:

• a lift link mechanism having a front link and a rear link provided in the vehicle body and spaced apart from each other in a vehicle body front/rear direction;
• an intermediate structure interconnecting one end of the front link and one end of the rear link via a pivot axis;
• a blade housing having an engaged portion engageable with an engaging portion of the intermediate structure;
• and
• a guide face configured to guide the engaging portion and the engaged portion to an engaging position in association with a movement of the vehicle body in the vehicle body front/rear direction so as to establish connection between the blade housing placed on a ground surface and the intermediate structure,
• wherein a power transmission mechanism for transmitting an engine power to a blade provided in the blade housing includes a vehicle body side power transmission mechanism and a mower side power transmission mechanism as units separate from each other;
• wherein a power coupling mechanism for coupling an output shaft of the vehicle body side power transmission mechanism with an input shaft of the mower side power transmission mechanism is supported to the intermediate structure;
• wherein the power coupling mechanism includes a coupling body having a first coupling end to be connected to the output shaft and a second coupling end to be detachably connected to the input shaft, a coupling holding portion for holding the coupling body, and an attaching unit for attaching the coupling holding portion to the intermediate structure while allowing displacement of the coupling holding portion in the vehicle body front/rear direction;
• and
• wherein the attaching portion causes the coupling holding portion to move linearly between a connecting position realizing connection between the second connecting end and the input shaft and a releasing position realizing release of the connection of the second connecting end to the input shaft.
