History of the Tractors

Jerry & Marsha Slepicka – Natives of Boulder, CO
Vanessa (Slepicka) & Trenton Bailey (Located in Billings, MT)
Jessie & Jenna (Carlson) Slepicka (Located in State College, PA)
Brandon Slepicka (Located in Longmont, CO)

Jerry and Marsha bought the vacant lot in 1987. Together they built the garage and log home. Every log was hand fitted exactly. They were required by Boulder County to keep the lot mowed. This resulted in our first tractor purchase, our 1946 John Deere B. Our second addition was a 1936 F-20 that Jerry bought during the auction of his grandparents’ homestead in Ashland, Nebraska. Marsha’s dad added the 1927 Fordson, a tractor he had on his homestead of Nauvoo, IL. The next tractor Marsha bought during the Boulder County Fair, while pregnant with the twins, Brandon & Jessie, a 1944 Alis Chalmers C.

More tractors were added over the years with the original end goal – sell them all to help the kids pay for college. That goal fell aside when the kids wanted to keep the tractors and won scholarships to pay for their college.

Brandon has taken over the weekly moving of the tractors. They are moved, the yard mowed, and then put back into a pattern. You will see the flying “V”, fight club, even square dancing patterns. He’s always open to new ideas.

In 2020, Brandon started collecting, restoring, and rebuilding Gibson tractors. The Gibson tractor company was located in North Longmont. He currently has 9 Gibson – all of which are considered garden tractors, although the company made full size also.

As of today, we have 16 full size tractors, 9 Gibson tractors, 25 hit and miss engines, and 12 small engines. The tractors are on display throughout the spring/summer in our front yard. In August, many are taken to the Dougherty Museum for the Yester Years Show. At the beginning of September, they are moved to the back and housed in our tractor sheds.


Why you ask?

As mentioned above, paying for college was the original goal. When that changed, we discovered that preserving these items provides a great teaching opportunity. Farmers who used these old tractors love to drop by and share childhood memories and stories of their past. Parents can show their children equipment that is no longer made and what it was used for. All the horse drawn equipment on display around the yard is from local homesteads around the Niwot area.

Niwot was primary made up of farms. Farming was the way of life. We believe that preserving and honoring this way of life is important. We appreciate that you took the time today to honor Niwot’s heritage.
