when the tractor begins hip hopping from rear tires to front tires off the ground, and when you look behind you, you see "pot holes" from tires squashing ever few feet into the ground...
plumb it inline for the FEL arm cylinders, would be interesting to see.
be nice if there was an "addon package" you could toss on the physical valves themselves. to reduce need for an actual accumulator. and just use tractors open center hydraulics.
be nice, if there was an "addon package" that allowed accumulator to slide inside the frame work of the FEL arms, or FEL arm supports. to reduce space taken up. by accumulators.
