So I got my 420 up and running, got the blade mount modified and working perfectly, and wouldn't you know it after working in the yard last night pushing piles of dirt around (for no good reason), on the way back to the garage it just stopped moving. Come to find out the bolt/spring washer/bushing backed out from the hydro linkage. Has this happened to anyone else? I was going to add a little Loctite red to hold it all there, but wanted to get a little input from you fine gentlemen.

Nick,

the one on my 420 was almost worn through. I replaced all the little pieces but the jd nylock nut didn't seem to hold position, so I got on of the skated all steel lock nuts, and didn't have another problem. the other note is the bolt that goes through is now much longer then the original, and I ended up cutting it down to match the length of the original I removed.

This doesnt have a nylock nut, it has a bushing (17) thats threaded that 20 screws into.

ok, you must have an earlier version. mine had a nut in place of #17, and the bushing was a stand alone part.
