Hello. Just wondering if there is a way to check my transmission that is currently in my John Deere 100 series mower without the mower running. I'm parting out this mower and want to remove and sell the transmission to someone who can use it but want to make sure it's working first. It's been so long since this mower was purchased I can't remember if the transmission was working or not. Can I just remove it and spin the pulley on top with something to see if there's movement? Any ideas would be appreciated.
