MTD will provide it to you. Check the link below. Type in that model number and use 1 as the serial number. Pick the 770-xxxxx choice and there you have it (accept the terms.)
Usually on the bottom of the seat.
You have given a serial number instead of a model number, so I have no idea what deck you have. You could get the right numbers and try:http://manuals.mtdproducts.com/mtd/public/list.jsp
There should be a model and serial number plate or sticker located either on the frame or under the seat. The engine also has a serial number and model on he base of the engine .
First look and see if the decals are still on the hood of the riding mower, if they are there those are the number of your mower.If the hood and/or the decals are missing then you need to find the serial number, which is located either directly under the steering column, at the back on the rear axle, or near the front on the side frame.Once you have located your serial number, look at the number. It should begin with the Prefix M00 and then the model number of the machine. For example if you find this serial number (M00318X222001) you would have a John Deere 318. Hope this helps.
Most Craftsman have the tag under the seat near the rear of the top plate.
You have given the serial number rather than the model number. Perhaps MTD could answer that, but I doubt anyone else could.
