After puttin her back in shed, noticed substantial dripping from under hood of TC40DA 2002 on left side when standing in front of tractor. Popped the hood and fired her up again. Dripping increased from left side of radiator cover. It's not coolant. Definitely hydraulic fluid. Can't see any spray or jets, but underside of hood wet with the fluid. Dripping increased to almost a spray for about 10 seconds after shut her off. Could the cooler be leaking backward??
