I recently bought a used Lazer Z to upgrade my equipment. My problem is that I have a customer who insists that it doesn't cut even all the way across. I replaced the blades and I think it looks better but I'm not sure if it did the trick. I have seen some of the areas he is talking about and I think they are scalp marks from his uneven yard. It isn't terrible but like most noticeable. I have also checked air pressure in tires and they are all the same. I am also wondering if he is seeing the tire marks from the mower. This client is becoming a pain in the a** but he is well connected and a local business owner, so I don't want to lose him. The more and more I look at his yard I keep second guessing myself if the mower is cutting even or not. All help will be a great help. P.S. I used to have a JD F525 and the quality difference is enormous. The problem with that is I can't compare the cut to old mower because the quality wasn't as good because of the mower in general, not because of something being wrong (F525).
