Don't buy this aerator! Bought a brand new one in 2012. Has 150 hours on it. The right shaft and tire fell right off in a clients backyard. how embarrassing it was trying to push this thing with one wheel to the front yard. Especially when the equipment is new. Took about 2-3 weeks to get it fixed. Then this year, second day of aerating, the other side falls right off. Called exmark directly and also called our sales rep and they said there is nothing they can do for us. How about that customer service? Looks like we will never buy another exmark product again, and we will keep telling this experience to everyone we know. We would of liked to hear that, here is another one until we fix yours" or something like that. But exmark just said oh well!!
Don't buy this product! When it works its fast, but remember, it takes about 2 hours every night to clean all the sprockets out because dirt and dead grass gets stuck in all the sprockets. Terrible design.
