I normally park the x590 with the mower deck or snowblower in the down position since it will drift there anyway. After cleaning up after out last snow fall I parked it in the garage with the snowblower up so that the melting snow would drop off easier.
When I went out there a few days later there was a small pool of oil under the front of the tractor where the snowblower attaches. Reflecting on this I had noticed some marks on the tarp I park it on when cutting grass after my wife had used it and didn't lower the deck. I had assumed it was just grass drippings since it had rained. Now I am wondering if that was oil also.
I know that the valve for the lift is one way and uses the weight of the attachment to lower. I am going to crawl under it later to take a look, but is the oil leak normal or is it likely coming out of the cylinder or hoses?
