    Why does the mower mfg put # of blades=3 blade length=21" Width of cut=60"

    I am wondering how the width of cut can be 60" when the actual cut SHOULD be labeled as 63".

    I have been wondering this so long.

    The decks are put in a "v". The blades are not lined up exactly three across.

    Blades overlap to prevent streaking

    ...because of blade overlap!

    Look under the deck and you will see that the middle blade is forward of the two side blades.

    The 3 blades are not lined up in a straight row.

    You have to have this overlap because to prevent uncut strips of grass in between the blades they would have to touch each other...if they were straight in a row. Imagine the noise and sparks if that were to happen!

    Do you follow what I'm saying?

    So would the same rules apply to my 48, and 50" mowers?

    Or is that just on 60" decks?

    My Exmark 36" Turf Tracer uses 2 18" blades, which equal 36"

    My Exmark 52" Lazer HP uses 3 18" blades, which equals 54", but with the middle blade offset forward it moves the cut width to 52", as mentioned above to overlap and have nothing missed between all 3 blades.
