Daniel Best (March 20, 1838 – August 22, 1923) was an American adventurer, businessman, farmer, and inventor known for pioneering agriculture machinery and heavy machinery. Early years In 1839, Best's father, John, moved the family to Missouri, where he built a saw mill to cut lumber for the local pioneers. Daniel Best spent the first nine years of his life here, before the family moved again in 1847 to Lee County, Iowa, where they took up farming and raised stock. In 1859, Daniel, following his brother, joined a wagon train heading west to Fort Walla Walla, Washington, where he was employed as an ox-tender and sharpshooter. Life in the West In Washington, Daniel was involved in gold mining, followed by working in sawmills and eventually building his own sawmill. While working in his sawmill, he lost the first three fingers of his left hand, which he later said made him begin to "use his head". He then moved to Sutter County, California to work on the ranch owned by his brother Henry Best, where he began inventing machines. Inventions Over a period of 43 years, Best received 41 patents, including an improved washing machine and combine harvesters. His first invention, patented April 25, 1871, was a portable grain cleaner and separator. Farmers had previously had to haul their grain into town to have it cleaned and separated, but the cleaner and separator could now be brought to the grain. The machine won first prize at the California State Fair in 1871. While continuing to produce grain cleaners, Daniel began working on a single machine that could combine grain harvesting, threshing, and cleaning. He sold his first horse-powered combined harvester in 1885, using the money from sales of this machine to invest in work on an improved design for a traction engine. Traction engine Best saw the need for an improved traction engine (now also known as a steam tractor) to pull his combine harvesters. He first purchased the rights to build a steam traction engine from Remington of Woodburn, Oregon in 1888, before making improvements to the design. Around 1891, Best began to experiment with gas engines to replace the steam engines on his tractors. He developed his first gas-powered tractor in 1896. To prove its superiority, he staged a tug of war between his steam tractor and his new gas-powered engine, demonstrating that the gas-powered engine could pull the
