reviews

"My first zero turn mower, WOW, I didn't know what I was missing! I cut my mowing time in half and my lawn looks awesome! The Power Vac Collection System did a great job on the fall leaves and was a huge time saver, I did not even have to leave my seat! The power fold deck makes maintenance a breeze. The mower is comfortable to ride and easy to maneuver around trees as well as under bushes and fences. Clean up is a piece of cake, no awkward maneuvers to clean the deck or change the blades. I look forward to mowing the lawn every time. My wife even enjoys mowing the lawn too! This mower has been a huge blessing it's given me more time to spend with my wife, children and grandchildren. Thank you Grasshopper! "

"I was very sick in 2011. I was in the hospital from Oct. 31 2011 to March 7, 2012. When i came home I could no longer walk. With the help of a lot of therapy I got strong enough to walk again, but my feet are still numb and I have a lot of back pain. I could no longer use my old lawn mower. I needed a lawn mower I could drive with my hands and that I could raise the mower deck with out straing my back, The [Grasshopper] lawn mower fit my every need. The easist lawn mower to mow with made on the market today."
