I have a Tomas 245hdk and having some hydro issues. I can tip the bucket down and it will pick up the front of the machine bucket when I let off the pedals the hydraulic leaks pack down. When I try to tip the bucket back up it will not even move on its own. I also do not have any aux. controls right now. when I turn the switch on and then hit the switch nothing happens. When I raise and lower the boom that all works. Does anyone have any ideas?
