Re: my Case 644 tractor....the users manual mentions that the drain for the hydraulic fluid is on the travel control valve...and if "what I THINK is that valve", then there is no way I could even get my fingers up to the back of it, let alone a wrench or socket! Can I just disconnect one of the hydraulic line connections under the tractor or is that going to screw something up. Any help here would be appreciated greatly!
