There should be a diagram label on the top left front side of the deck (As seated on the machine)
Cub Cadet.com should have the manuals for this machine. (They are free the last time I checked)

I have a similar machine except it has a B&S engine. I just got finished earlier in the season rebuilding my deck and replacing the drive belt & tensioner idler pulley. These are well built but can be a little difficult to work on.
They are entry level commercial units.
