    My powersteering on the mower is heavy when i first start it. It remains heavy until ~ 5minutes of usage. It may be due to putting in the wrong hydraulic fluid in it a few months back. So I was going to drain and replace the it. Any tips on how to do this. Also what hydraulic fluid spec do I need to put back in it and approx how much.

    thanks !

    Does it go back to normal completely when it warms up or is it still sluggish. It sounds like you might have sheared the charge pump pin. How are your lift circuits?
