I know it's been discussed before on here, but my searching turned up 40 series parts. We have a 4255 that goes thru at least 1 shaft a year. It mainly pulls a fertilizer spreader and a 3pt sprayer. I need to replace the load shaft in it again soon. Are there any better options than a John Deere one? They seem to only make one year at best. What have you found better or is JD parts the better.
