I've owned my DK4210SE for quite awhile. Yesterday, I had a challenging task removing an asphalt driveway. I was able to complete most of the work, but the tractor suddenly died this morning. After troubleshooting, I discovered that the fuel filter was clogged with ice and debris. I replaced the filter and the tractor started working again. I learned a valuable lesson about the importance of regular maintenance, especially in cold weather.
