A newby to this site and to an Exmark Viking Hydro. Looking for advice on a few problems that I noticed pretty quickly with the zero turn versus other mowers. - When making turns on the lawn, how do you avoid tearing the lawn under the pivot wheel? I had little swirl areas under the wheel where grass was ripped up or embedded in to the wheel. - How do you smooth the start/stop to keep an even cut height? I found that at the beginning of rows, I had a little "wave" going on as I popped a wheelie. Any other advice or tips on getting a smooth cut? My finished product was a little ragged. Thanks for your help.
