My 2 year old Husqvarna YTH2348 Makes a horriable sound when blades are engaged. I didn't hit anythng just started making sound so I shut it down. Checked under it and inspected belts, everything

SOURCE: Zts has no Power when Blades Engaged

check the coils
I had the same problem 1 coil went out.
I replaced both to save time and money later

SOURCE: Knocking in mower deck or belt clutch when engaging blades, motor bogs / slows down

YOU MAY HAVE A BENT BLADE OR EXESSEIVE BUILD UP UNDER THE DECK

SOURCE: Blades will not engage on Husqvarna riding mower.

Could be a broken belt, loose belt (stretched) or something is under the mower deck jamming the blades. (stick for an example)

SOURCE: blades making a bad noise

Well I would say you have a bent blade, a blade has a loose connection to the bottom of the mandrel, or a mandrel bearing is going out. Visual inspection will reveal much, just look under the deck. A bad mandrel may appear to have "runout" when viewed from the top while spinning as contrasted with a good mandrel. Viewing the one in the center while deck is working is going to be a challenge. If you decide to replace a mandrel, do yourself a favor and take a picture of the deck belt before you take it off so you know how it goes back on.
