I have 2 JD F1145's both have 72 inch decks one deck is still cuts ok the other one has had a bunch of repairs and has about done , my question is what other decks could I use to replace it with either 60 inch or 72 inch ? I just tried to use a 60 inch deck from a F911 but the gear boxes on them are offset and tried both lift arms (F911 and F1145) and even switching them left to right but could not get the deck to attach where the gear box is centered . Thanks for any input
