I've got about 15 hours on this mower now and the quality of cut is not good.Even after checking the level of the deck,twice.It is SPOT on !I found after a third check why it would scalp in areas and leave lines in others.The deck wheels are not even ! Now as I said the deck is level,checked on a level smooth concrete floor.The wheels on the left side are fine but on the right side the front wheel is about a quarter inch highter than than the front left.The right rear is too low and nearly touching the floor.There is just no way to get an even cut with uneven wheels.It seems either the brackets were not installed correctly or the holes were not drilled right. I will see my dealer this week .And I'll get back with you all on this.
