Son has a T190 with a high flow (26 gmp) aux hydraulic fittings on the boom. He just took the bucket off and put on a clam shell type bucket. Apparently the clam will open, but not close. I asked him how it worked and he said it is solenoid that switches the supply and return hoses to make the bucket open and close ??
I plan to go over on sunday and help him trouble shoot. I have no clue how this works as I have not operated the tractor. He said something about having several buttons (el switches ) ? Is this just a solenoid that moves a piston to switch the two ports or ? Any common problems I should know about ? Easiest way to trouble shoot ? Normally an electrical problem or hydraulic spool prob ?
