Rumor has it you can thank Ford tractors for onboard hydraulics. I find this thread interesting as I haven't had to deal with this and it hasn't occurred to me how it would work without onboard hydraulics.
I guess these are the reasons MF went to onboard hydraulics. However, if you matched an OC baler with a CC tractor, the baler may let all the hydraulic flow just dump back to tank when the baler is doing nothing, rendering other remotes on the tractor useless. Meanwhile a CC system like what your tractor has will typically use a variable displacement pump that can maintain high pressure constantly, but at down to 0 flow resulting in less oil heating. This would cause the hydraulics to overheat. So say if you had an OC tractor and the baler was CC, the pump is always displacing oil so it'd be moving full flow oil over relief whenever the baler is not demanding anything (which is the majority of the time). The only purpose of configuring the baler as OC or CC is to match it with the tractor hydraulics so they don't overheat. Whether the system is open center or closed center, the remote should always be engaged at all times. The baler needs a constant source of hydraulic power to operate the density system as it is constantly monitoring the baler load and firing the increase and decrease valves on the baler as necessary to adjust the chamber. Well the good news is the solution will be easy!Not sure what any bad news would be. We have hundreds of operators and repair manuals for your Hesston equipment.
