Hey Loren ACG!

Was at a local parts yard today and saw this plow. Never saw or been around a case plow this new. Been reading about your plow and the hydraulic reset. Is that an accumulator Ella is pointing at? Are those cylinders more like shock absorbers? Does the bottom just snap back or do you have to stroke a remote to get it back in place? Looks like they are a nice plow.

John; Yes that is the accumulator, and that plow is exactly like mine. The bottle has a bladder in the top ene of it and you put a precharge of nitrogen gas in the bladder. Precharge of nitrogen is normally 1250psi., but can be varied. I precharge the bladder to 1350psi, because of all the rocks and hard ground we have.
To make the single acting cylinders keep the bottoms in the home position you open the manual diverter valve which is Tee'd into the tail wheel cylinder circuit, and you pressurize the other side of the tank that contains the bladder. This forces oil in between the tank's outer shell and the blatter, compressing the nitrogen gas. You can put a secondary charge of oil into the reset circuit up to 300psi. over the nitrogen charge, and once you have reached 1550psi in the reset circuit you close the diverter valve and the reset circuit is totally separate and independent from the tail wheel circuit. As long as there are no leaks in the reset circuit, you do not have to do anything further. It is a stand alone pressurized closed circuit, that operates without any intervention.
When a bottom trips the oil in the single acting reset cylinder is forced out of the cylinder barrel, (all cylinders tee'd into common line to accumilator) and compresses the nitrogen bladder even more, and when the bottom clears the obstacle the nitrogen bladder expands forcing the oil back into the barrel of the cylinder resetting the bottom into the home position.
It works very similar to an "air-ride suspension system on semi trucks, only much higher pressure.

Thank you for explaining that to me. Was looking at the system on the plow but just wasn?t sure how that actually work. Does that plow pull fairly easy? We had an old semi mounted five bottom case plow long time ago that we pulled with an 830 and that pulled very easy compared to the neighbors four bottom John Deere!

My 8358 plow is a 5X18. I pulled it for 2 seasons with my 931 in 4th gear most of the time. It has Radex conversion bottoms on it.

Hey John!! That plow will pull a lot easier than Loren's plow because it looks like that plow has the CASE Bottoms, not those hard pullin' White bottoms that Loren has to struggle with. We have one of those also, a 4X18 w/ easy pullin' CASE Bottoms. Great Plow!! Better grab it before Loren runs out there & grabs it!!

Gee John, I didn't know that I was struggling with the Radex bottoms. I am struggling with some brittle WEISE replacement landsides though.
The snow we got friday and yesterday has melted so I am going into self isolation in the nice warm cab of the MX and finish up plowing another field down on the lower farm this afternoon.

Other than some fertilizer spread, I haven't seen any field work around here. This clay dries slow.
