⚙️ Tractor History Maker of the Week: Rock Island Plow Company (Heider Tractor Division)
🌾 Founded in 1885 in Rock Island, Illinois, the Rock Island Plow Company began as a trusted maker of horse-drawn implements before stepping boldly into tractor production in the early 1900s. When it acquired the Heider Tractor Company in 1914, it set out to make mechanized farming simple, smooth, and dependable.
Here are a few interesting facts about this Midwestern powerhouse:
1. 🧠 The Heider Tractor featured a unique friction-drive transmission that let farmers shift speeds without grinding gears — an innovation far ahead of its time.
2. 🛠️ Rock Island offered a range of rugged tractors built for the family farm, combining simplicity, power, and serviceability.
3. 💔 Despite strong engineering, the company couldn’t survive the Great Depression and closed in 1937, but its mechanical ideas lived on in later Minneapolis-Moline designs.
From plows to power, Rock Island helped bridge the gap between horse-drawn equipment and modern tractors — leaving behind a legacy of ingenuity.
