Hello eXmark, Last summer I had to stop using the eXcalibur Mulching blades w/mulch kit because of numerous customer complaints....the grass looked pushed down...it was not lifted properly prior to cut. This happened w/more than 1 unit & w/more than 1 set of mulch blades...we were cutting @3"-3.5". I switched to notched eXcaliburs w/mulch kit & the cut was beautiful...no more complaints. Now I'm trying to run the mulch kits in the spring...cutting 2" w/notched & there's allot of under deck build up occuring. I'm going to try solids which have less lift & should reduce under deck build up w/the mulch kit? Unrelated to above question: Why do you claim solids give a better cut than notched in normal conditions? The notched have better lift so should in theory produce a nicer cut especially at higher settings?
