Any Zero-Turn Mower Experts?

Power steering systems will have aeration in the oil when you first put them together. Had that happen with a Corvette. Had to let it sit 24 hours and make sure I had all the air bled out of the system, warm it up and do not over fill or under fill it.

Think you were saying you just serviced your system with new oil and filter, may just need to let the air work out of it.
