The light is coming on that says Hydraulic Filter Restriction on a John Deere 250 Skid Steer. It won't come out of part now. The other day I was using it and the boom suddenly wouldn't go up. I still had bucket tilt control and the machine would move forward, etc. My question: If I change the filter, would it make sense that it'd fix my problem? Not trying to ask an obvious question but while I wait for the filter to come in, I'm curious to know if I should be thinking of another problem. History: The boom wouldn't work (up/down or tilt) and the skid wouldn't come out of park. I replaced the monitor (unit with all the buttons) and also a solenoid that had a wire chewed through it by a rat. The wire caused a short and burned out my monitor. So, that was fixed and all was well. But, a few days later, I now have this problem. I am sure the hydraulic filter hasn't been changed for years (if ever; with 2,000 hours). So, my big question is: If the hydraulic filter was becoming plugged, would those be the symptoms to expect... have forward/reverse and tilt on bucket but not up/down. I kind of makes sense to me as tilting the bucket isn't that much load but raising the boom is... The other thing that is making me wonder is that I filled up the hydraulic fluid with Orscheln's Premium "303" Tractor hydraulic fluid (says recommended for JD: Hy-Gard use) as I replaced the monitor, etc... Put about a gallon of it in to top it off.
