Help with belt logistics

[cfawcett22]

I just purchased a Toro Z master commercial mower. He told me that the bearings on the center spindle need replacing. I’m not 100% sure as to what each pulley is and the belt diagram for the PTO. I was wondering if anybody could shed some light? If you need more pictures, let me know. The first picture is from the right side looking through to the left side of the mower and the second picture is directly under the mower looking from back to the deck.

I would suspect that the spindle he was talking about is on the deck. Post the model and serial numbers for the unit so we know what you are talking about.
