Have you tried calling the 2 Main John Deere dealer chain stores here in Upstate NY to ask them about swapping out your deck? Land Pro - Cazenovia being the 2 main John Deere Dealers with several stores in Upstate NY. I am in the reverse situation as you. I have a 54" deck needing a 48" deck because my path to the back yard is just wide enough for the 54" yet the sides rub on concrete. Both stores said when they find a 48" deck they will do an even swap because the 54" is work more money. Which I don't care I just don't want to rub the sides of deck.
