I bought an Exmark 52" Lazer Z last spring. I have loved the machine as well as the support for that machine. At least till now. I take very good care of my equipment. It is serviced at the dealer where I purchased it. I have the oil and filter changed every 25 hrs, at the same time the air filter is checked and cleaned and the machine is greased. Well after I finished mowing a very large property, a car dealership, I noticed that one of the clamps on my air filter box was gone. The plastic cover was broken just where the clamp was fitted to it. Today my dealer says that Exmark will not warranty the cover. They said,"The customer could have put it on wrong or hit something with it". As I said the property is a car dealership. It is wide open mowing with no trees or anything else to hit. And as I stated the only time the cover comes off is at the dealer. I dont understand why Exmark wouldnt stand behind a machine that is serviced as mine has been. I guess that being loyal to your dealer and the manufacturer doesnt pay.
