    The day's of me paying at least $18 per blade for JD O.E.M. blades are over. I really like to support my dealer but he has made PLENTY off of me in last two year's. I am going to aftermarket blades exclusively this year. My question is this: I need to know the center hole measurement's of the blades but I can't find it in my manuals, JD's website and my dealer doesn't even know. Does anyone know the measurements of the following: 997 72", 777 72", 757 60", 717A 48", 7H17 48". All I need is the center hole dimensions. I know I could go to the shop and measure them myself but that would require me to go out in the snow and cold. That's not happening today:)

    I actually bought a 737 Deere last week. The standard blades on it are massive. About double in weight compared to my exmarks. The center hole for it is 7/8. The 757 is 7/8 also. I am not positive on the other mowers. Center holes for most commercial mowers are 5/8. One web site is There are a few others also out there.

    Do you have a way to measure it yourself?
    JD can be a pain trying to find blades for, especially if you want a blade other than the stock style blade. They use oddball sizes for many of their blades.
    Generally speaking for:
    48" Deck Blades= 29/32", .904"
    54" Deck Blades= 7/8", 13/16", 51/64"
    60" Deck Blades= 7/8"
    72" Deck Blades= 29/32"

    on the j.d website, go into j.dparts, search for each mower model, then break the search down from the menus, it gives specs on each blade.
