Buyers beware of some tractor and equipment service manuals offered on CD.  These are POOR quality scans of original manuals.  These sellers are breaking the law and you will be assisting them by buying their shoddy homemade copies.  Ebay should boot these people - but they would give up and leave if you would think about what you are buying and stay clear of these ripoff manuals.  1st class reproduction service manuals can be bought from legitiment sources for same prices as these clumsy amateur scans - that you will regret using.  Don't be fooled by slick photos and ads - stay clear of shoddy Massey Ferguson and other  tractor service manuals on CD.  Don't fall for this scam.
