A Tradition of Customer-Centricity

The Rotochopper brand has long been synonymous with “Perfect In One Pass” grinding precision and simplicity. But the history behind the Rotochopper name is much more than innovation in grinding equipment. It’s about a group of people with a different philosophy toward waste materials and a unique focus on customer success. The Rotochopper brand began when two companies from different industries joined forces to manufacture unique recycling equipment. Our co-founders, Fred Peltz and Vince Hundt, established our core values of customer-centricity...

Fred Peltz, Rotochopper Co-Founder

In 1980, Fred Peltz was a recent high school graduate in central Minnesota with an astonishing ability for building, repairing, and designing machinery. Raised on a dairy farm, he learned at an early age the fundamentals of hard work and mechanics. By age 14, he was repairing equipment for local farmers.

New Challenges

Always looking for new challenges, Fred would study equipment and find ways to improve it, or design new machines altogether. He quickly developed a reputation for innovation based on customer input. In the late 1980’s, his obsession with designing better equipment solutions led to the creation of Rotochopper, when Fred came across a piece of paper recycling equipment and decided he could build a better machine.

Vince Hundt, Rotochopper Co-Founder

Raised 250 miles from St. Martin, MN on a 400-acre diversified Wisconsin farm, Vince Hundt also learned a great deal about machines at a very early age. In 1973, after attending the University of Wisconsin for three years, Hundt purchased and began to operate a dairy farm near Coon Valley, Wisconsin. Dairy farms in this area tend to be half cropland and half woodland, and Hundt saw opportunity in the marketplace. Vince founded Poplar Coulee Ridge (PCR) Inc. in 1982...

In 1973, after attending the University of Wisconsin for three years, Hundt purchased and began to operate a dairy farm near Coon Valley, Wisconsin. Dairy farms in this area tend to be half cropland and half woodland, and Hundt saw opportunity in the marketplace. Vince founded Poplar Coulee Ridge (PCR) Inc. in 1982 to import and market farm-sized European forestry equipment to utilize the local farm woodlots as a source of saleable wood fiber. The concept quickly took off, keeping Hundt busy with the sales of skidding winches and wood chippers.

paper animal bedding

Scarcity Drives Demand

In 1988, a severe drought caused crop failures and created a need for new sources of animal bedding. At the same time, recycling mandates had created a glut of unwanted newspaper in the hands of waste haulers who lacked equipment to convert this waste into a saleable product. Hundt saw opportunity in these unwanted papers, and designed a one-of-a-kind system that incorporated a John Deere hay baler, a wood chipper, and a sheet metal cyclone to output farm-sized bales of chopped...

A Partnership and a Better Solution

A PCR baler showed up near St. Martin, MN, where Fred Peltz had the opportunity to get his hands on it. Fred quickly envisioned several improvements to the design and decided to call the PCR number. He introduced himself to Vince and suggested that he had the facilities and abilities to build more efficient recycling equipment that would be easier to operate and maintain. The two entrepreneurs struck a deal and a friendship. From that day forward, all manufacturing was...

The First Rotochopper

In the summer of 1990, the 1090 Newspaper Bedding System built by Peltz Manufacturing made its debut, incorporating a newly designed paper chopper with a 30-horsepower electric motor, and a newly minted name: Rotochopper. This system was immediately popular because it was durable and easy to use, and it set the industry standard for ability to make the necessary particle size. This equipment design philosophy—focusing on precision particle size control and customer needs—set the foundation for all Rotochopper engineering.

“Perfect In One Pass”

As we expanded into new applications, a commitment to finished product control continued to shape our engineering. We focused on designing equipment that would not only provide the end product specifications our customers needed, but would do so conveniently and consistently. To this end, we developed a screen change system in 1996 that remains the fastest and simplest way to change screens to make different products.

This patented technology allowed wood waste handlers to easily enter the growing landscape products market. In previous years, wood waste handlers were able to sell their ground wood for $10 per ton for fuel, they were now able to sell the same wood for $60 or even $100 per ton.

Shocked By Tragedy

In the spring of 2000, we experienced a horrible tragedy. Fred Peltz, while overseeing completion of a factory expansion, fell from the roof, and died from his injuries a few days later. Our company, our town, and our customers came together to fill the church, the town hall, and Maine Street in St. Martin to honor a truly wonderful, energetic, and creative man.
