1200 with 44c deck
 

I just got a 1200 running and it has a 44c deck on it. I'm not sure which belt I need. Could someone point me in the right direction?

You will need to change the Center Pulley as seen on the 44A deck. Once that is done, then the IH-490489-R2 belt is used.

Thank you! I believe the pulley has already been changed so hopefully I can order the belt and be good to go.

So if the pulley has been changed, what is its diameter?

The OD for the 44A Mower Deck is 4.50".

Just to throw more mud in the water,
An "A" deck pulley designation, accepts an
"A" belt ( 7/16 /15/32 / 1/2") width belt.

A "C" deck pulley designation accepts a "B" section ( 5/8") width belt.

Please understand this is CCC/ I/H's system.
not industry standards!

As industry standards list:
3/8" belt or 3L
"A "section 7/16-1/2" or 4L
"B" section as 5/8" width, or a 5L
"C" section as 3/4" width.
Many more, but not a point of this post.
