Hello all, 

I have an MTD ride on mower and I'm not able to find the operators manual or parts list. 
The details from the sticker under the seat are:
13A1450D659
Af199L10101
B 10
 
On the MTD website it asks for the model and serial numbers. When I put the serial number in it says 'Not found'
 
I'm wanting a replacement cutting deck belt but I need to know the part number so I can get the correct size. 

I found a deck belt on Amazon - just put in the model no and it came up. I don't know how to post a question on this forum - I would like to find a service manual for model no 13AL606G730. We put on the new deck belt but can't figure our how to reattach one of the the tension springs .
