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!
