If you actually did "top off" with straight hydraulic oil, not a tractor hyd. fluid, I am going to assume that you were maybe a quart low? What have you got there? a 5 or 6 qt system? If you were fairly close to an oil change anyhow, I probably wouldn't worry too much about it. It's not as if you dumped gas or insect killer in there. A quality AW hydraulic oil is not going to wreck your engine, just change it out when it's due. If it was a new John Deere 6115D with 40 hours on it and under warranty still, I'd probably stop it out in the field, mud and rain and all, and change oil!!
