I messed up and cut my PTO shaft off, too short. I have a Woods RM360 mower. Will other brands of PTO shafts work with my mower?
Sorry to hear about your problem. Please review this from Everything Attachments before taking a saw to your new PTO Shaft. How to Measure and Cut a Tractor PTO Shaft - YouTube
You could also measure your old PTO Shaft after viewing the video and ascertaining what the correct length should be, then as has been suggested check to see if an extension is available without buying a complete new shaft.
