John Deere 2720 issues

[nutforbriggs]

My 2720 has 700 hours on it. For the past few months—light use— I’ve noticed the hydro drive is louder, the steering “chatters” after warming up. Machine has had regular service to include hydro filter and screen cleaning/ change. Use Lo Vis HyGard. Before I get into charge pump issues, does anyone feel that switching to regular HyGard—to include another filter and screen cleaning may help?
