    HEY can any and everyone that is running double blades post a little comment about running this set up .....

    How it does ( on what kind of mower and size) as far as quality

    If any troubles with bolts breaking or blades hitting etc....

    Does it decrease power ... etc...

    Does it get blocked or clog the shute..etc..

    I am thinking of trying this

    I have a 52" lesco walk behind

    I was wondering the same things myself. Do you need a longer blade bolt for the ZTR mowers such as the lazer z hp?

    No need for longer bolts. I have a lesc ztr 48" that I running doubles on works great just make sure you have them correctly aligned. (+)

    Do you see any advantage to useing the double blades? Is it harder on the electric clutch? Also do they stay aligned properly or shift after a full days work?

    I use doubles 95% of the time on my Hustler 27/60 Super Z.
    Advantage over singles is....
    Better clipping distribution
    more lift
    less clumping
    seems to help the striping a bit.
    great in the fall with leaves (double gators)
    They do use a littlle more hp but not enough for me to notice.
    I also use the stock bolt when using doubles.

    I just set up doubles.

    use a square to align them.

    i used 1/2 longer bolts and torqued them 75ftlbs.

    gators on top of stock blades

    lowered deck baffle to lowest position, helped with blowout. Excessive front blowout before.

    used them both ways, with and w/o mulch plate installed, plan on purchasing a trimmer trap. More side blowout with plate installed.

    i bump my clutch engagement to get the blades started...not sure if this is harder on it or not, at full throttle the clutch bogs a little if i don't bump.

    This IS the setup that I prefer.
