I have been having some troubles with the 7020 hydraulics lately. It has been on the batwing and has trouble lifting the mower. It struggles to lift the mower I think due to air in the system cause some times it will go down before it goes up other times it is just slow till it can work through the air and finally lift. The hydraulic fluid in the rear end has small air bubbles in it as well. System is over full at this time cause I added fluid thinking it was low due to the air bubble in the sight glass. Yesterday I topped off fluid and headed out to mow. Hydraulics acted normal at first then it was gradually back to the normal air in system indications I had before. Are there common hydraulic problems with these that can cause it to suck air? Is there a suction filter on this tractor?
