The operation method of hydraulic flipping plow is as follows: there are generally two types of hydraulic flipping plows, one without an automatic reversing valve on the oil cylinder, and the other with an automatic reversing valve on the oil cylinder. The operation methods of the two types of hydraulic flipping plows are different when flipping. For those without an automatic directional valve on the oil cylinder, when flipping, the hydraulic lifting handle of the tractor is used to first lift the flipping plow to the highest position, and then the multi way valve control handle is manipulated to flip. When manipulating, the control handle is first pushed or pulled. As soon as the flipping plow crosses the center line position, the multi way valve handle is immediately operated in the opposite direction, and the flipping plow can be flipped over. When the driver first operates it, there may be a phenomenon of not being able to flip over due to unfamiliarity, but after familiarization, it can be flipped over smoothly. However, the driver should try to maintain stability when manipulating the flipping to avoid causing significant impact on the plow frame and causing the whole vehicle to shake and swing; For oil cylinders equipped with automatic directional valves, flipping operation is much simpler. When flipping, simply move the multi way valve control handle in one direction to complete the entire flipping process, without the need to reverse the control handle.
