DAMN brother!!! In my time (5 years ) in the Army I've never seen that kind of set up. We had a D-6 cable blade and D-5 hydraulic blade but then again I got out in 1973. Never saw a system such as what you speak of. I'd be right there with you in as who designed this cluster fu#!! k. I'm going to look up you model but I can't guarantee I'll be any help. Damn thing looks like an alien hybrid.
Though that wouldn't stop me from fondling & groping it. Keep us posted as this has my mind running in a squirrel cage.
