We received the TR3 rake here in Calgary a day earlier than expected. Excellent work, thank you very much to you and your team for for a job well done! I finally got a chance to work with the unit on my gravel driveway- about 800′ of potholes! I must say. Wow, what a perfect machine! For a unit with no moving parts (other than wheels) and what it can do it is simply an amazing machine! The combination of 3 basic functions into 1 simple design, is absolutely genius! I worked slow getting the feel of the unit and experimented with some of the settings. It didn’t take long to find that this thing works great and I’m so impressed! My wife and daughter thought I had extra gravel brought in but I didn’t. They too are very impressed. My daughter can’t wait for me to work the riding arena- if it’ll ever quit raining! Thanks again for everything!
