I can't find anything with the same model number as yours in the parts lists Shane, so the easiest solution is if someone with a Greenfield looks at your pictures and recognises the detail. The hard way is for you to pick some detail that varies from one Greenfield to another, and go through all of the parts lists item by item to find one the same as yours. Then you could look at the cutter brake for that model. In between those two extremes is asking a Greenfield dealer.
