Changed hyd. oil, new filter, still not enough lift on 3 point with mower attached or fel. By passed FEL still no luck on 3 pt lift. On a Zennoh ZL1802FD what should hyd,. pressure be on the 3point lift? Is there a check valve or relief vale that may be stuck open? Hope someone can help, next step is tearing the pump down. Thanks in advance.
Rebuilt pump Friday, all is well.
