bush hog pts shaft for 2020

[DogT]

I seem to have lost the front half of the PTO shaft for my ancient 'Rebel' 5' bush hog. I was looking at this Amazon.com: Complete Tractor New 313-623 Universal PTO Driveline Compatible with/Replacement for Rotary Mower 146542 CS511SM PM146542: Automotive, will it hold up to the 2020 HP or do I need a stronger series shaft? Unfortunately it doesn't say what series this shaft is. It looks like I need about a 48" working length for the shaft measuring the PTO to drawbar ends and the mower smooth drive to the drawbar couplings.

Well, that rebel bush hog was pretty much beat up by the 2020 which is way over powered for it. The A frame to attach it to the 3 point hitch is really beat up and bent and that's the second one. I did measure the original U-joint and it's 1 1/16" x 2.5" so it looks like the original pto shaft was a size 4 but how that relates to a series is obtuse. Probably series 12 or 14 at best, I never had any problem with the shaft, the bush hog was just not up to the 2020. I really should have a 10' mower, but I don't want to spend the money, they're not cheap. I do have a 451 NH mower, but it leaves the grass laying there to rot and it gets worse as time goes by. But I can cut with the NH in half the time because it cuts a full 7' at one pass, if it doesn't clog up. Plus my place is very steep with trees and rocks around.
