I have a 5 year old Lazer Z Liquid Cooled 60# with a deck that cuts wayyy too low. It cuts about 1.5" lower than the stated height. Also one side is much lower than the other. I did what the usuers manual told me to on how to adjust, but it did almost nothing to adjust the crookedness. There was no advice on how to "raise" the deck per setting. Does anyone have expeirience in handeling this problem? some help would be appreciated. oh, yeah the tires are full pumped up, so thats not the problem. Thank you.
