I think its a murray, but need help.

Ok this may sound dumb but i have this old mower that i paid nothing for and have run the heck out of it. Its marked a lawn general 46" 3 blade deck. 18 hp 14 speed. Here is my problem. I have no model or serial number. It runs two belts to the deck. One runs from the motor to a dual pulley on the left side of the deck. There is another belt that runs from that pulley to two other pulleys including a tensioner. My issue is the belts finally have stretched beyond use and i need to replace them but have no idea what i need. I should also replace the drive belt as well. Any help would be greatly appreciated.
Thank you

Does this deck engage with a big handle that also lets the blade deck down?

No it doesnt. It has a separate pto lever.

Its close but the double pulley is on the left side of deck. So ultimately right now the one blade will engage but the other two wont. The belt is stretched i believe.

Can you post all engine numbers, so I have an idea of an approximate year?
