Thought I would add some stuff I had found and ask for help on things I haven't. The Air cylinders that drive the presoak direction need to have air tool oil put in them regularly, if they seize on you the part number for the WW 2.0s is NCMC125-0200 and I found them on the web for about $33. Has anyone bought the bearings for the track wheels? Also, the boom lovejoy keeps going out on me about every year, any thoughts on why?...where to get them other than JC? Thanks
