I have a 7040 and when I shut it off it starts a fluid leak out of the hydraulics. What causes that and how do I fix it.
Thanks

its pushing hydraulic fluid out of the tank ?? ......... Vent plugged ? ... sounds like your building up pressure inside.

Do you mean the couplers are leaking?

You can get new ones.

There is a few steel lines that have a square o-ring on the end where they attach to the trans housing or anything around the hyd pumps could be leaking too.

You just have to track it down...wash the tractor and see where it leaks.
