A Grundy County man’s lifelong interest in chainsaws has grown into one of Iowa’s most unique museums.
Mark Heimann says his passion for chainsaws began out of necessity, evolved into a hobby, and eventually, the Heimann Saw Shop and Museum located in Dike.
“We always, when I grew up, supplemented heating with firewood. So we always had chainsaws around. When we built our first home and the next place, again, we were supplementing heat with firewood. So I always had chainsaws around. So I was always interested in them. And then fast forward a number of years, the kids are graduated from college. God has been good to us and I have a little disposable income and my wife introduced me to eBay and I started looking for a chainsaw like the first one that I had.”
Heimann’s search for the first saw he owned, led him to become one of the most recognized McCulloch collectors in the country.
He says the museum now features saws from the past and new saws that help tell the story of how the industry has evolved.
“In addition to the McCulloch, I’ve been able to accumulate some very nice examples of early saws. Again, Reed Prentice, Mall was another U.S. manufacturer of chainsaws very early on. And then as well as some of the more modern saws, just because it sort of bookends the whole story, you know, from the humble beginnings to where we are today and the way that the industry has developed.”
Heimann is currently expanding the museum to make room for more displays, literature, and documentation. He hopes to have the work completed by early December.
In addition to his collection, Heimann keeps parts on hand for repairs and offers maintenance services.
The Heimann Saw Shop and Museum is open daily from 8 a.m. to 5 p.m. Visitors are encouraged to call ahead to confirm availability. Heimann can be reached at 319-239-4813.
