alright right off, i get some bearing abuse and clutch wear, we tryed this on one of our heavy fert irrigated lawns 10" of growth a week. I ran 2 bobcat ztr side by side w/ out bags different blade config. One - ran reg high lift discharge heavy clumps. 2nd - ran highlift with gators so each spindle had two blades looked like a plus sign- busted up the grass so fine you didnt need to cross cut. I can mow wet grass w/ almost no clumps, now thats how i run all the time.
