I've found 2 used machines I'm interested in. Ones a 3830 with 350hrs the others a 3540 with 500 hrs. Asking Prices are within 500$ of each other, the same in my book. The 3540 looks brand new, not even the bucket looks scratched. The 3830 is also beautiful, but the buckets been used. Doesn't look abused just normal paint wear from going into piles. They seem to be the same tractor, except the 3540 is the newer version of the 3830. All being equal is one better then the other? Neither have emissions, both nice heavy tractors both have the 700 series loafers and qa buckets with loaded r-4's. Thanks for the input.
