A draper platform (102) has a suspension system. Two hydraulic cylinders (306, 406) are disposed on the left side of the draper platform (102) in fluid communication with a gas-charged accumulator (506) to form the first hydraulic circuit (502) and support the draper platform (102) on a gauge wheel (218). Two additional hydraulic cylinders (510, 512 are disposed on the right side of the draper platform (102) in fluid communication with the second gas-charged accumulator (514) to form the second hydraulic circuit (504) and support the draper platform (102) on a gauge wheel (220). Valves (518, 520) control flow to the first and second hydraulic circuits (502, 504), respectively, to permit an electronic control circuit (500) to separately and independently fill and empty the first and second hydraulic circuits (502, 504). |
