Sutech mower manuals

Sutech currently makes three commercial 33"-cut walk-behind mowers, called the Stealth series.  They only have one owner's manual, one parts manual (including wiring diagrams), and one service manual available on their website, which apparently are supposed to apply to all three models -- except for the parts manual, which is for models SSD33B13 and SSD33BE13.  All three manuals are also listed here.
