The hydraulic reservoir on the case 730 should be in about the same area as the case 630......on the right side of the tractor at the rear of the engine and on what would be the bell housing is a large cap screw type plug. There should be a dipstick not too far from it....you add hydraulic oil there, if it is a case-o-matic. If it is a standard transmission, then the dipstick and the plug should be on the rear of the tractor around where the seat bolts on.
