Looks like there are some people on this site that are very knowledgeable about M-F tractors and attachments. I recently purchased this plow and would like to know the model as well as any points of interest that you may know about it. (Is it a poorly designed plow or very good?). Also, did it originally come with a rear gauge wheel? There are two holes which protrude beyond the rear bottom-just wondering if a wheel once bolted on there?? Any help would be appreciated.
