Hi Iceman, welcome to Outdoorking. If you have time to search our archives, you will find quite a few threads on repairing and maintaining Greenfield ride-on mowers, and most likely some of them will be useful to you. I'm not familiar with your MTD machine at this point - that will be something new to our archives.
If you have questions or problems with your machines, please start a new thread in the appropriate forum, and we will try to help.
