The info I said above was from my dealer. I asked about the 1428 and he said they don't make them anymore. BUT like what was said above, I guess they stopped in 2004. Maybe your dealer has one around... Call back or go there and ask about the 1523. BUT you would think (if he doesn't have one) he would know they stopped making them. LOL maybe that is why you haven't gotten a price, because he is waiting for someone to tell him what they cost.
IF he has one, you know you should pay FAR less then what was said above... I would think you could get into the 1523 for that price.
I LOVE the 15 style. I ended up getting a 1533 for around $18,750 with MF-1525 FEL, 60" box blade and 72" rotary cutter. (the box blade and cutter are Kodiak made)... Did I get a deal, don't know.
