Case 830 rockshaft and PTO housing removal. Stuck rockshaft piston.

In this video since we've figured out the only reason the draft arms on the Case 830 won't drop is a stuck piston. So with Connors help we lift off the rockshaft housing and also the PTO and hydraulic pump housing because the hydraulic pump pickup screen is ripped. Just how bad is it when water enters the tractor transmission and hydraulic oil reservoir? It's BAD!! It must be the additives in oil mixing with water to create a gooey snot like substance that is difficult to rinse out. Also we are expecting the hydraulic pump is burned out but we remain hopeful it isn't.
