    How many of you guys are using them?

    Are any of you using them on something other than a Dixie Chopper?

    I just started using them yesterday.

    Med.lift and gators....for dry 5-7 inch tall fescue and bermuda. Catching up from wet spell and the 10 days/bi-weeklys growing FAST got a little tall.

    Love it! Dusty-but no need to double cut to deal with clippings! This combo shreds and throws them nicely.

    I run a Lazer Z w/ 23 Kaw. and 60" deck. No problem with drag when chopping at 2-1/2" (blades as sharp as Ginsu knives and CAREFULLY balanced) :D

    Several of you members that use Exmark have emailed me about where to get the double blade bracket. Have any of you bought them? I am wondering if they do work on an Exmark or not, they should but I would like to know for sure.
    Thanks

    I use them on my lazer 60" Gators on top, standard high lifts on bottom. No bracket, the blades dont move at all. I like it.

    It will be alot better when my OCDC come in.

    HAS ANYONE HAD TROUBLE BENDING THE BRACKETS FOR THE DOUBLE BLADES? I BENT ONE THIS WEEK SOMEHOW. I DONT RECALL HITTING ANYTHING. BUT IT SURE IS BENT ALL FOUR LIPS ARE BENT LIKE THE BLADES TWISTED. IF IT CAN BE BROK I CAN SEAM TO FIND A WAY.
    ALSO IS ANY ONE USEING BLADES THAT HAVE BEEN CRYOID(not sure of the spelling). THAT IS FREEZING THE BLADES. I HAVE BEEN RUNNING THESE FOR THE PAST 2 YEARS AND INSTED OF CHANGING THE BLADES AT LEAST ONCE A DAY I CAN GO SOMETIMES 2 OR 3 DAYS BETWEEN SHARPING.:angel:

    EricELM:

    No Bracket. All my local Exmark dealers said: "???HUH???"

    No Spacer between blades.

    Torqued at 140 lbs. (better safe than sorry)

    So far...so good. :)

    Anyone who tries this:... remember to compensate for the 1/4" loss of heigth under the deck and be sure to re-adjust the scalping wheels accordingly! Also try to get 2" bolts of #8 hardness.

    I compensate a full 1/2" in to be safe. Works and stripes real nice! :D

    I just started using them yesterday. They did great. Gators on top of med. lifts. I'm running a Gravely PM260Z.
     
  9. USING DOUBLE BLADES IS DANGEROUS

    I have tried this before on a W/B and did not see a diferance
    they did not stay on straight

    I also don't think the manufactures want you to do so or they would have done it them selves

    I would check with the man. site and see what they say about it

    your mower spindle wern't made to hold the extra stress

    got to differ on that godfather,think about a toy jack,as in pick up jacks. is it balanced better with two sides or four.
    in any case they were a major improvement for me.to each his on later
