I've done stupid things before, but might have topped myself. Ran the hydraulics on my machine in very cold weather without warming it up, assuming incorrectly that moving the fluid was best, and after much noise and hesitation, all hydraulic function ceased after about 5 minutes, including loader, 3 pt hitch, and steering. Haven't found any threads, probably because noone else has been this foolish. Anyway, looking for advice on how bad it is, if the pump is repairable or replaceable if I've ruined it, etc. Thanks in advance.
