    You don't need longer ones on Dixie Choppers but I don't know about Exmarks.
    You can ask here; http://www.exmark.com/contactus.asp Or post in the Commercial Mowing section.

    If you have adjustment washer stacks on the spindle, just remove one washer per spindle and add the blade. If no washers and you have the through bolt type the bolt should go all the way through the nut with extra blade installed. If the blade bolts through the bottom with a short bolt, stack the blades and measure how much bolt is left. You should have 1 1/2 x the bolt diameter bolt length available to thread into spindle.

    You do not need to change the blade bolts to run double blades on the lazer. I've got a 2004 60" lazer with an air cooled 27hp Kohler on it and I run doubles a lot and have never had any problems with it. I have to engage the blades at a slightly higher RPM is the only difference. I haven't tried running doubles with the UV yet- afraid it might take too much power away or burn up the clutch.
