Hope someone can help me, I picked up my first real tractor yesterday a B7500 with just 60 hours it looks like the previous owner barely used it. Anyway after trailering it the 80 miles home I noticed as I was going over it again the right rear wheel did not have the bolt or cotters going through the wheel hub on the inside of the wheel like the left side did. I am assuming that it must have loosened and fell out or is this only on the left wheel of the machine? These are the bolts etc. that enable you to widen the rear wheels. One other thing the owners manual shows agrease fitting on the top link but there isn't one there ? Any help would be much appreciated, I apologize about the lengthy thread. Thanks
