Fuente: WIPO "honey" An agricultural apparatus may comprise a transversely extending main frame. The main frame may be configured to move upwards on a side when subjected to a lifting force on that side. A stabilizer apparatus may be inter-connected to the main frame and be transversely spaced outwards. and may be operable to provide support against downward acting forces. A pneumatic system may comprise at least one frame gas suspension bag and at least one stabilizer gas bag may be located proximate the stabilizer apparatus and may be in pneumatic communication with the at least one frame gas suspension bag. When the at least one gas suspension bag is filled with a pressurized gas, and the stabilizer apparatus is subjected to an upwardly directed force, the at least one stabilizer gas bag may be compressed increasing a pressure of the pressurized gas within the at least one stabilizer gas bag. Pressurized gas in the at least one stabilizer gas bag may be communicated towards the least one frame gas suspension bag, to increase the gas pressure within the at least one frame gas suspension bag, which creates a lifting force on a first side of the main frame, to cause the main frame to lift upwards.
