    I see there are a lot more people than I first thought using primarily 21" mowers. I am in the same boat, and wanted to see what kind of blades everyone was using? I see all kinds of stuff on Meg-Mo's and Gators etc. and wondered if anyone has a prefernece on blades and the 21", or if they found it didn't much matter.
    Thanks for any input in advance.

    I'm using Toro's stock blade for the time being, but will probably be experimenting in the next month with all the leaves.

    I am using a gator blade on my commerical LawnBoy and have been very happy with it compared to the stock blade.It mulches better and the edge holds up a lot longer.If you're using Toro's atomic blade I don't know if the Gator would be any better or not,as the atomic blade is similar to the Gator.I don't have any experience with the Meg-Mo's,so can't comment on them.

    the atomics are a copy of the gator except they don't have as much lift. I prefer the gators for leaves.

    for mulching I have found that medium lift blades in combination with a 1/2 inch negative deck pitch gives the best results.

    if I'm going through lots of heavy growth or Bahia grass: I put a low lift blade on, and a 1/2 inch negative deck pitch. the low lift blade, while not standing the grass up as much as I would like, has less air Resistance, leaves more HP for the engine to work with in those situations.

    I like high lifts for side discharging, medium if the grass is wet.

    bagging: I prefer medium lifts, no deck pitch.

    overall, I think that medium lifts are the best multi-purpose blades if you don't want to be swapping them out every day.

    hope this helps.

    I am glad to hear I an not the only one using a negative back pitch! I have read all over to set the front deck pitch one notch lower for best results, but have found that only tends to blow out the debris from the front.
    The atomic blades do resemble the gators, which is why I asked.
    Thanks for the comments, and keep them coming.
    I did contact meg-mo, and they replied that they didn't have a system for 21" models as of yet. I'd love to hear otherwise though.

    Bolt up doubles on the 21" for Leaves...W/the Prolines use a Toro Gator on Top and a Lawnboy gator (or any blade w/no lip) on bottom.
