Mine is: 0147 E1
The info the seller is giving is : 0137 F1
I'm sure it's "E", if it's not a valid code.
Engine Model #s are the same: 407777
The difference between these 2 "Type" numbers is :
Mine: 0147
His: 0137
Just wondering if they might be the same muffler....
AND what the "Type" # means.
I've done a google search for a decoder .... No luck.
This is the info the guys has:
"Scotts Lawn Tractor Model 46580X8A. All items tested and in good shape as described. Engine was a Briggs 407777 0137-F1 20HP unit."
I have a Murray tractor ... Not too concerned about tractor fitment. Mostly concerned about muffler fitment. (It's a muffler guard). So muffler size is a concern.
