I have recently purchased an old international Harvester cub cadet like my dad and I used to use to run his tiller in the garden growing up. I’ve always wanted one. I have the tiller that he had and was trying to get it hooked up but I keep running into problems. The last problem I have is I received a mule drive from my nephew which was on my dad‘s old cub cadet that I believe was from the 60s but the belt drive pulley on the motor it’s too far back so it lines right up with the shaft that holds the mule drive pulleys. So I am assuming the mule drive Is different on the later model ones versus early model cub cadets? I am running out of time to plant my garden and I’m trying to get the tiller to run. The serial number on my tractor is 2050046U463884. I don’t even know what year or model it is because someone spray painted it. I’m going to restore it when I get it all going. I just need help finding the correct Part number for the mule drive I need it finding a mile drive period. I would so greatly appreciate any help. I love these tractors!
