Just purchased a used 90xp with the Perkins . The tach goes into test mode each time its started and stuck on hours cannot switch to rpm. The auto feed does not seem to be working right and the tach is IEC . Please advice
what type of hydraulic fluid would my 625 gravely chipper take ? Also I am leaking hydro fluid from a relieve valve from chipper and is worse in reverse from the feed wheel. Thanks for any help
