I told EGO that I was having a problem "sucking up" leaves and small twigs, etc., with the mulching blade and they recommended that I purchase the Hi-Lift blade. I just used the Hi-Lift blade and noticed that the cut seemed more even and it did cut leaves, twigs, etc., however, it didn't "mulch" the grass anymore. There was grass remaining in the rows cut, requiring me to go back over the same spot I mowed. And, as a result, the battery power only lasted about 60% of the lawn and I needed my back-up battery to finish the job....didn't have power problem with the mulching blade. So, do you want to mulch the grass without the suction or do you want the suction without the longevity of the 7.5 amp battery and do nearly twice the mowing because you have to practically go over the lawn twice? I am so used to mulching that I think I will have to stick with that....maybe in the Fall, when the leaves fall, I'll switch back? But, it would be even better if EGO could solve the best of both worlds; that would do the trick, right?
