Good evening everyone 😀. This is my first post on the forum. I am a Exmark user at work. So the 60 inch Lazer z is missing grass spots as am cutting, dry , dewy or wet grass. On all speeds low, medium, and high. I have religiously blown off the deck twice a day. Checked the belts and blown off the deck spindles. I have scraped under the deck and checked and sharpen the blades at least once a week or when it needs it. I have greesed the main deck spindle and checked the greese where the blades go up after I take the blade off and put it back in place. I use the red ExMark blades on this machine. I also replaced the deck belt not long ago. I did check to see if one of the blades was not turning as I pulled the deck belt with my hand . No problems there. Is there something am missing? 🤔. Thanks for reading my post. God bless. Jeff

With the deck belt off, rotate the spindles looking for a free spin condition. If you feel a drag or noise, no dice.

You say you have greased main deck spindle, what about other two spindles?


On my unit there is a main spindle in the back middle and a in gauge clutch ( PTO ) on the back that has to be greased. The other 3 spindles are checked and greased when I take the blades off to sharpen them. So am cover on that end. Jeff

I have done that and they all spin freely. I just sent the mower in to check on the deck and I thought It had a cracked spindle? A college kid hit a sewage drainage lid a few years ago? I thought that might be it? Everything checked out good and is working order I was told by the Exmark dealer repair shop. I will take the blades off again and make sure they are greased well and put them back on. I also blow under each spindle after I get done cutting for the day so there is nothing causing any binding issues and are free to spin. I also blow the deck clean twice a day as well. Again fairly new belt on the deck. Jeff
