Full Model number? Drive bet between engine and transmission turning the top pulley and fan on top of transmission? Fan may have broke and was noise, and has broken the belt!

It's an Mtd platinum 76 sd
On the body there is 25/107h
Is that the model number
Customer: replied 1 year ago.
Belt in tact
Sorry
Expert:  Curtis B. replied 1 year ago.

Model number will be example 13W1243b560. Is the top pulley turning on the transmission with engine running and clutch out? Look up under fender to see it. Drive belt is above the deck drive belt.

Sorry
My workshop doesn't have lighting so can't check transmission or pulley spinThere were 2 numbers under the seat
1st number
13A1793g686
2nd number
AEO97L10022I'm happy to ring you if it helps
If I can have your number
It's my call to pay for
My tel number***********
Expert:  Curtis B. replied 1 year ago.

No need for a call at this time. Did you look at the link I sent showing the drive belt arrangement? And need to find if the belt is turning the pulley on the transmission. Will mower roll in freewheel position? Or could the brakes be locked?

Expert:  Curtis B. replied 1 year ago.

And your model number is ***** shown under MTD.

Customer: replied 1 year ago.
Free wheeled fine and foot brake works ok
As far as I can see it has a single belt around the pulley over the rear diff , the belt then goes under the engine but I can't tell how many pulleys between diff and engine.
I've assumed the two numbers under the seat contain the model number. The only other number I can see is the logo 25/107h
It will be easier if I can look in the light in the morning if that's possible
Regards
Expert:  Curtis B. replied 1 year ago.

Did you look at the blet link I sent? Is this look like yours? Need to verify your model number when you can. Link is below.

Customer: replied 1 year ago.
I will give you a better idea in the morning if that's ok
I appreciate your patience but I'm 69 and it's a bit of a sprint up and down and I'm looking underneath the mower by torchlight.
Can I ask if the pulley has a shear pin or anything because i can check that in the morning as well
Also am I in the right place under the seat for the model numbersAgain appreciate your patienceRegards
Expert:  Curtis B. replied 1 year ago.

Sure, I'm 70 myself, and the pulley has a woodruff key that keeps it from turning on the shaft.
