PTO issues John Deere 1530

Thanks to all who have helped me in my journey so far. I have been able to get most of the small issues fixed and today took my new to me tractor bush hogging for the first time. As I have stated in my previous posts this is my first tractor and I bought it knowing I would have to do a lot of work to it. I can’t really afford a better tractor right now. Anyway I made a pass and a half around the half acre area that I had a mulcher clear for me in March(the stuff had gotten about 12 feet high) it is mostly weeds with a few sweet gum saplings about the size of my little finger so it was no strain on the tractor. Then I hit a mound of dirt and had to raise the brush hog. Now when I engage the PTO the shaft barely turns. I came back up to the barn and it is leaking around the PTO shaft. My question is how hard is it to replace this seal?

I did look up what parts I think I need and I think the seal is T22069 the gasket is T22080. I am not sure but I may need gasket T21997 as well?
