Abstract
A power transmission device includes a first shaft provided to be rotatable around a first rotational axis of the hydraulic pump driven by the engine. A second shaft is rotatable about the first rotational axis to rotate the power take shaft. A clutch is rotatable about a second rotational axis that is substantially parallel to the first rotational axis and is vertically below the first rotational axis. The clutch has a first rotating portion and a second rotating portion arranged to face each other in the second rotational axis. A first rotating portion is connectable to and separable from the second rotating portion. The first rotation transmission mechanism is configured to transmit rotation of the first shaft to the first rotating portion. A second rotation transmission mechanism is configured to transmit rotation of the second rotating portion to the second shaft.
