just noticed today my hitch is behaving very slowly, in the drop mode. valve is full open, fluid is fresh and clean and filter just serviced. any ideas? even with 3-400 lb blade on it drops very slowly. thanks to all.
forgot to say, this is a yanmar ym2500. also, hitch doesn't go all the way down. arms get in horizontal position then stop. makes it hard to hook up sometimes. thx
