Yard Machine 46" Deck & Drive Belt Questions

[ClappedOutCessna]

Hi all,
New guy on the forum and this is my first post. I have a Yard Machine model 13AM77LS058, serial number 1C162B10278, DOM 03/2012. It has a 20 horsepower Briggs & Stratton Twin model 461707. I've tried uploading pictures but I get an error message saying my image files are too large.

I just purchased the mower used and it needs new deck and drive belts. It has a three-blade 46 inch deck. The trouble I'm running into is that every parts diagram I have found shows my model having a two-blade 42 inch deck. Adding to the confusion is a sticker on the front of the right fender denoting a 46" deck for this machine. The sticker appears to be original from the factory. If it weren't for this sticker I would guess that someone removed the 42 inch deck and installed a 46 inch in it's place. All that to say, I'm really scratching my head over this one. If anyone has any insight or ideas as to what belts my mower needs, I'd really appreciate the help. If more information is required, I'm happy to provide it.

That model number is coming back to a 2012 Murray made by MTD. Somebody has switched the seat and transferred the seat pan with it which contains the model number tag. Get the complete model number off of the engine complete with the code should be able to obtain the correct model year to narrow down the possible actual model number

Several ridings from the 2000 model year used that engine.

13AI607H019/088/118 or 13AI608H026/062 or 13AI673H352 or 13AI675H062 or 13AI699H088/118

The / numbers that I included are basically the same mower made for different companies.

What country are you in ?
A lot of the MTD stuff sold outside the USA will have serial numbers not recognised on the USA web sites
I have a dozen Yard Machines in my service run & none of the numbers are recognised by any retailer .
The deck & mower combinations seem to be Australia specific
