How come every used R series sprayer we've seen has the square tubing behind the nozzles on the center section bent?  Granted we may not have looked at every sprayer but we've yet to find one that isn't either bent or just replaced.  We just bought a used R4038 this year and did some straightening when we got it but would like to know what seems to be the issue.  They are way back behind the driver and it's impossible to see from the cab so there's that.  Only other thing we could think of was vibration causing cracks at the bolt holes.
