I have an exmark next lazer z that I bought new last season. It is the new deck series with a 60" cut. I had alot of blowout problems last year with spring and fall cleanups. With the high lift blades all the dead grass from the thatcher blows out from under the front of the deck. Same problem in the fall with the leaves. Deck was adjusted acording to owners manual with 1/4 inch difference front to back. Was talking with the exmark rep and he said with the 60" deck 1/4 inch was to much and to drop it to about 1/8 inch. So I did and still have the same issues. Switched to low lift blades and problem solved, well kinda. Now there is not enough suction to pick up loose grass off the sidewalks or drives. Am going to try some extreme blades to see what they will do next. Has anyone had issues with this and what did you do to solve the problem. Thanks for your help.
