I'm working on an older Morris chisel plow/deep tiller.... the CP 725 ... it's a 24 ft. model with cylinders that are plumbed in series, the outside ones are down when the machine is down, the 2 inside cylinders are fully extended. I'm familiar with the annoying cultivators that used different size pistons as you go down the series, but this is different. The cylinders were starting to leak so I took them all in for new seals. Now I can't get machine back in sync, and the cylinders won't lift the machine straight off the ground for transport. The instructions for the IH air seeder made by Great Plains was also plumbed in series, but on that one you just started with all the cylinders disconnected and moved the oil down the line as each one extended. This one doesn't work that way. There are no ports to move the oil to the next cylinder, it depends on the oil on top of one piston moving the next. This leaves 2 challenges... a) you must remove all the air to prevent compression, and b) all that air needs to be replaced with the correct volume of oil or the cylinders won't move in sync. I've tried manually filling the cylinders one at a time while the machine was retracted, and will try it again with the machine jacked up off the ground and the wheels extended, but this is driving me knuckin futz.... any suggestions?? My next move might be to make T's with long hoses to raise and lower each cylinder individually with another tractor.... working with this system makes me realize why Morris was looking for receivership protection...
