I just took off my grappler and put my bucket back in. I put the dust caps on the end of the hydraulic lines. Yesterday I noticed a puddle of hydraulic fluid under the fitting. I relieved all the pressure before I took them off my tractor. It is stored inside a shed. With it being warm in Va. and in the shed. Could that make them leak? Sorry if I sound stupid with some of my posts. But I’m a new tractor owner and are learning as I go. Thanks in advance
