Hello Mowers: A month ago I bought a used Snapper Riding Mower from Bender's Mowers in Pinellas Park, FL. The manual says that at the highest setting it should mow at a 4 inch height, but I'm only getting 2 and 1/2 inches. (I'm 56 years old and have years of experience with St. Augustine lawns, which I believe should be cut between 3 and 1/2 and 4 inches.) After adjusting the deck as high as it could go, the place I bought it from is now uninterested in my issue with the mowing height. So, I'm thinking I should buy and install bigger wheels on the mower. Has anyone else ever tried this? The mower is a Snapper 301014BE.
