    I just bought an older 36" Lesco WB. I can't figure out how to get the blades off of it. I did a ton of searches and found that scag w/b's have a similar set up. The lesco has what I believe is a bolt upside down holding the blade on that runs through the spindle to a giant 1 15/16" nut to the pulley to a standard 15/16" nut. Do I have to take the entire assembly apart to get the blade off? Any help would be great!

    ok ...you have to loosen the top nut, but you have to put a wrench on the bottom of the bolt. after you get the nut on top of the spindle off. lift the mower up and the whole bolt with the blade should slide out. the spindle stays in place.

    I did that, but there is still a large 1 15/16" nut under that holding everything on also. I'll try to get a picture soon.

    Well I had to cut this down 6 times but it eventually fit into the 800x800 pixel limit. Anyway, you can see the way the whole thing is put together. Now I just am not sure how to take the whole thing apart, or if I need to. Hope this helps anyone. I was told the mower is about 8 years old.

    This is how I get the blades off manually on the Toro:

    Picture 1 is the bladetools that are used on the bottom, notice the breaker bar.
    - The ratchet wrench is 1/2" drive cuz I busted too many 3/8"s this way.
    Picture 2 is the adjustable wrench that goes on top.
    - If you can, see about wedging the top wrench some kind of way, so it stays in place while you have both hands free (and be careful).

    Note: Be VERY careful, the mower in these pictures has the deck supported by a jackstand - It CAN fall off if you don't watch it, but in 5 years I have never had it do that to me, anyway...

    The bigger the wrench, the better...
    Somehow I don't think you can get too big a tool, but I know you can have too small, and it won't come off.

    Topsites, you got that big breaker bar, how much torque is on those spindle nuts? My tiger cub manual says to tighten them to 75. The 1/2 inch ratchet works for me.

    I think I'm just gonna start taking stuff apart and figure it out the hard way. The extra large nut in the middle is what will be dificult. I'll have to buy a bigger wrench I guess.

    Oh I dunno, but I forgot to mention that's just to get them OFF!
    I mean, seeing how the thread starter appeared to be having some trouble.

    I never used that breaker bar to put them back on, just the ratchet and nice and snug and let'r be, I think they're designed to stay tight anyway but snug 'em up good and that's it (or you'll curse me later lol).

    Sometimes you can get them off without the breaker bar, but I use it when I'm done playing around lol
