This is not a WILL FIT belt but an exact oem specification size belt. I can sell you a cheaper belt as well but you get what you pay for. A will fit belt (like almost all eBay sellers have listed) is like a shoe that doesn't fit right but "will fit" and if you have ever worn a shoe that doesn't fit right you know how it feels. .63"X 172.843" HEAVY DUTY MADE WITH KEVLAR REPLACES: JOHN DEERE TCU26908 Model numbers with a 54" deck Z810A Z820A Z830A Z840A Z850A If you do not know the part number or the size of the belt please email me and I will see what I can come up with!
