Shane, this site has no repair manuals for Greenfield mowers, but it does have illustrated parts lists for several models. I have not heard of a repair manual, though perhaps they exist for dealers only.
If you look at past threads you will see that several Outdoorking members have made repairs to Greenfields, and have reported on how they did it, with pictures. The problems have been mainly in the clutch shaft and clutches, plus adjusting the chains.
We can probably go through a similar process with your repair project if you wish. It would involve you posting detailed pictures of each issue, then we would offer suggestions, and you would report back on your repairs. When completed, your repair thread would be a part of Outdoorking's archive, so others could consult it later if they had similar problems.
