Customer Question
will not lift the blade...
I have a 2011 450J LGP dozer. All of a sudden the hydraulics will not lift the blade up down or sideways. If you turn the machine off and start back up it will work sometimes for days and others for about 5 minutes until it acts up again. The codes that come up are as follows 523789.31 and 523781.31. Any idea what to do to repair this problem?Shawn Stobo
