Abstract
A rotary cutter has a deck assembly including a central unit to which a wing unit is attached for flexing vertically. A hydraulic cylinder is provided for lifting the wing unit 90° to a fully raised transport or shipping position. Located above, and extending generally parallel to, the hydraulic cylinder is a telescopic strut incorporating a spring which becomes compressed as the wing unit approaches its fully raised position, the compressed spring unloading to thrust the wing unit down upon pressure being released from the hydraulic cylinder, even if the weight of the wing unit is tending to keep it in its raised position. Wing unit may be locked in its raised position by inserting a pin through the telescoped members of the strut when the latter is in its fully collapsed condition.
