About Kasper Rock Master in Pierz, MN
Founded by a Farmer Who Knew There Had to Be a Better Way
When you're clearing rocks from fields or job sites in Pierz, MN, you need equipment that actually works the way you do. That's exactly why Ted Kasper, a lifelong farmer and professional landscaper, created the Rock Master and Dirt Master—tools born from years of frustration with inefficient skeleton buckets that trapped rocks and removed too much valuable soil.
What started as a solution for his own farm over 15 years ago has grown into a patented product line trusted by farmers and contractors across the country. Today, we ship anywhere in the United States and proudly serve local customers throughout central Minnesota.
We believe in building equipment that saves your back, speeds up your work, and keeps productive soil where it belongs—on your land, not in your rock pile.

Discover how the Rock Master can transform the way you clear land in Pierz and beyond.
Ted grew up hand-picking rocks on his family's small dairy farm, learning early how demanding the work can be. After years of wrestling with equipment that made simple jobs harder, he engineered a smarter design—one that separates rocks cleanly and efficiently without stripping away topsoil. The first Rock Master was built strictly for personal use, but once neighbors saw how much faster and cleaner it worked, word spread quickly.
In Pierz, where farms stretch across rolling acres and rocky soil comes with the territory, you need tools designed for real conditions—not just theory. Every weld, every angle, and every feature of the Rock Master was tested in the field before it ever went to market.
We're proud to support farmers, landscapers, and contractors across Minnesota and the entire country, helping our community and yours work smarter and more efficiently.
