thanks for all the advice that makes sense then. I have the battery and starter off already so now i will check under the battery box today and start looking there. thanks alot glad i didnt already split the tractor.
After i started hearing the noise while brushinging it was a real faint hitting noise like something hitting round in a cirlce. it only happened when i had the PTO on. Then after i had it in the shop and was running the PTO with no load on it at lowest idle the noise got louder then made a giant thud. thats when it was locked up.
You can still spin the PTO by hand from the back when out of gear.
