I have a Deere 3520 with a Normand N74 Hybrid blower on the 3 point. I've been reading about shock failures of 3 point hitch parts while motoring down the highway and hitting pot holes or bumps. I understand the fix would be to add a shock absorber of sorts in the hydraulic system. A nitrogen accumulator can be used to mitigate the shock failures. I know the theory of nitrogen accumulators, What I need are specifics like manufacturer part numbers, where to T into the hydraulic system, hydraulic schematics, sizing requirements, mounting locations and success stories. So, anyone out there done this before?
