I have a 2002 Lazer Z HP, 23 Kawi, 52" On good lawns.... it cuts better than I could ever hope for. I have found that, as many others have commented, it clumps badly in wet, or heavy growth. I have tried different blades / combos / doubles combos. It seems that the clumping is MUCH worse if there are any weeds or crabgrass in the lawn. "Clean" Lawns with little weed growth seem to cut fine in almost all conditions, except tall & wet, which I can understand. The problem I have is that I get A LOT of clumping on some lawns (with weed content) even in DRY, REGULAR GROWTH conditions! I use Mo-Deck on the deck, but at $8.00/can... it gets a little pricey. When a lawn is tall, I use my 8 yr. old SCAG 14HP WB,.... it cuts better, and disperses clippings better.... WHY??? That's hard to swallow when I think about what I paid for my eXmark..... really gets me MAD! I met another LCO yesterday who asked me "I see you have an Exmark on your trailer..... WHY?!?!?" He had bought one and brought it back to the dealer 2 weeks later for a different machine..... Why?..... CLUMPING !!! It seems that lift of the blades actually contributes to the clumping, because when I throttle down, or disengage the blades, the deck will drop a HUGE load of clippings right there in one big mess as the blades "spin down"........ really inconvenient if I need to disengage in the middle of a lawn to move an obstruction, etc..... leaves a mess in the lawn for me to clean up........ Would low-lift blades work better in TALL or WET growth?? Anybody ever tried anything different? Any other suggestions from the eXmark camp???? Would appreciate any help with this... I'm gettin tired of double cutting because my $7500 mower decided to blast 5 lbs of clippings out on every-other pass. Thanks for any help.
