I bought my first disc-style cutter about 10 years ago and was very hesitant because I had heard horror stories about people breaking windows on their tractors. There were other very crude styles of devices, but nothing that I wanted to mess with. I have always liked to build things so I started doing different designs by hanging rubber flaps from a framework. Through many different designs and materials, we have found something that works very well and is easy to install, and keeps serviceability in mind. On our larger kits, the curtain hinges in the middle and swings out easily from the ends so the operator is able to service the machine easily. Our kits are often cheaper or about the same price as replacing a window. With that said downtime and operator safety is also very important to us. We want to eliminate downtime and keep operators safe. In 2013 I purchased my first disc-style mower. At the time I had my 3-year-old son, Dane, riding with me in the tractor. We didn’t have any sort of rock block on the new mower at the time. I hadn’t used the new mower for an hour then “BOOOOMMM” the side window exploded. Dane was in shock and said, “Holy COW dad, what happened??” It’s funny now but was quite scary at the time.
