AC plow Model??

With hydraulic reset, probably a 2000 or 3000 monoframe plow. Looks a lot like my 2000 monoframe plow.

2000 mono frame, also available in spring trip, I have 3 of them in various conditions.

Non-stop plowing with those auto-reset bottoms and rubber spring coulters. Make sure the accumulator is charged properly with nitrogen and then set your oil pressure to 800 psi and adjust it from there to keep bottoms from needlessly tripping back.

There were not many options for coulters in the plow bottoms book I have. The rubber ones probably are the least likely to work for decades without coming apart.

My 2000 4x18 is spring trip I guess, I've never tripped a bottom because I got the boulders out of the field while plowing with a smaller plow. I haven't used a plow in about 18 years.

The operator's manual tells how to fill the nitrogen reservoir. It doesn't use tractor hydraulics for resetting the bottoms. It uses tractor hydraulics to operate a cylinder on the furrow wheel at the back to raise and lower the plow and the three point for the front end.

One last thought. There is quick disconnect hydraulic coupler
on the nitrogen can. What is that for?

The tractors hydraulics ARE used to establish hydraulic line pressure for all of the plow bottoms. That's what that hydraulic connection is for......to make the 800 psi starting pressure. Some soils plow harder and will require more pressure that that. The idea is to not use anymore pressure than is necessary for your soil types and ground speeds. Those accumulators are quite reliable, but remember, that plow is possibly 40 years old. The plow bottom linkage allows the plow bottom the trip back and then up to clear the rock obstruction due to the linkages geometry. Competitors plows caused the share point to go down lower as it tripped back.

Yes, the accumulator is kinda like the air in a cold water tank bag.  It limits the pressure to 800 PSI.  Without it, normal pressure is about 1500 PSI.  No real danger other than the fact that it IS a pressure vessel.  It should be checked visually for deep rust pits or cracks, then charged.  Reason they use Nitrogen is that it is largely inert, and does not contain water, like compressed air, and the nitrogen that is supplied commercially is supplied in higher pressures, in the storage tanks.  Any place that does shock or tire work should be able to sell service or point you in the right direction, as to where to get the Nitrogen, in question
