    Doubles and clumping?

    It seems to me that the lift of the blades actually contributes to the clumping..... when I throttle back or shut down the PTO, I will get a large discharge of clippings that wil drop right there in one deck-sized clump! (this only happens with wet conditions / heavy growth)
    Seems like the lift created by the blades actually holds the clipings to the underside of the deck.

    Here's what I'm thinkin'.... Would using low-lift blades, or one blade in a set of doubles with no lift, help? I'm thinking this would contribute to mulching of clippings, without disturbing airflow as much.

    Has anyone tried this?

    Where can I get blades with no lift foil on them?
    Someone posted a pic of one once, but I don't remember the source.

    The best combo I've found is Gators over Hi-Lifts.
    I only run doubles in heavy growth or wet conditions.

    Has anyone come up with a better combo??? Lets here it!

    I've thought about "reverse gators"...

    Soo far, my exmarks wll not cut wet or even damp grass! :angry:
    We raise the decks up...then just have to double cut.

    We're waiting until late morning to start mowing, but I get stringers....or clumps if I drop the deck low enough.

    BIG PROBLEM. :mad:

    I'm running single highlift excalibers...doubles don't do good on my mowers.

    Is Your Deck PITCH Set Where Its Supposed To Be? Even wet Grass My Lazer will Cut Great But i Will Have Lose Clumps To Pick Up.

    I cut one with 12 days growth (about 6-7" tall) at 3.5" today immediately after a thunderstorm (water still running down the gutters) and had minimal missed blades and minor clumping with my 48" lazer Z hp . Check your deck pitch and try for 1/8" to 1/4" higher in back than in front. This was on Tall Fescue btw. Also, worn blades that are rounded on the tips could cause some problems. Some guys use blades a little too long before getting new ones.
