  "textContent": "A convertible top (26) operating mechanism includes a bi-directional hydraulic pump (52) which is selectively connected to top-operating hydraulic cylinders and tonneau-operating hydraulic cylinders (42) by a two-way, 5-condition control valve (58) to selectively raise and lower the top (26) and tonneau (30). A mechanical linkage (40) connects the top-operating cylinders (42) with a movable rear bow (B4) and is co-operable with a spring during operation of the top-operating cylinders (42) when fully extending and initially retracting to move the rear bow (B4) to enable tonneau operation and to seal the top on the tonneau.",
