Need some advice on a 38 inch LT-150 Mower Deck

I need a new 38 inch mower deck for my 2001 John Deere LT-150. Apparently not any 38 inch deck will do, but is there a serial number or part number for my existing deck? and does anyone know how long the LT-150 decks were used? In other words, will any 38 inch deck from an LT-150 work as a replacement for my damaged deck? Or are there some limitations?

Post your model number and I can tell you what newer deck will fit
