Patent ID: 7686720

Claim:
A portable power take-off unit removably mountable to the rear of a pickup truck for providing power to construction and farm equipment and machinery, comprising: a framework for disposition on the bed of the pickup truck; the framework including a pair of space-stakes that are securable to the respective sidewalls of the pickup truck; a power take-off shaft capable of selective operation at a high speed and a low speed; a sprocket and chain assembly interconnected to the power take-off shaft for driving the power take-off shaft at either the high speed or the low speed; a belt and pulley assembly interconnected to the sprocket and chain assembly for driving the sprocket and chain assembly; means for supplying power to the belt and pulley assembly for selectively driving the belt and pulley assembly; an idler pulley for selective tightening of the belt and pulley assembly whereupon tightening the belt and pulley assembly engages the power take-off shaft and for selective disengagement from the belt and pulley assembly thereby resulting in the disengagement of the power take-off shaft; and a manually operable engagement lever connected to the idler pulley so that raising the engagement lever disengages the idler pulley from the belt and pulley assembly thereby disengaging the power take-off shaft and releasing the engagement lever causes the idler pulley to tighten the belt and pulley assembly thereby resulting in the engagement and operation of the power take-off shaft.
