Hello, new here. Have a 9n, hydralics were a little shaky, then replaced the safty valve and hydraulics work better than ever for about 2 days, now will not lift the box blade. Pulled cover off and didnt see no fluid churning so safty valve should still be holding.
Any ideas what to check? Want to hook up a gauge but don't know where to get one with 1500-2000 psi.
