An adjustable deck system including: a first, stationary deck; a second, rotatable deck partially overlying and pivotably mounted to the stationary deck; and a device for rotating the rotatable deck relative to the stationary deck. The rotating device includes: a pair of support brackets spaced from each other and secured to the stationary deck; a first shaft fixedly secured at its ends to the pair of support brackets; a traveling block slidably mounted on the shaft; a device for moving the block along the shaft; and a link pivotably secured at one end to the block and at its other end to the rotatable deck, whereby when the block is caused to move along the shaft, the link causes the rotatable deck to rotate with respect to the stationary deck.
