# Roths Industries

Roths Industries, Inc. (1945–1960) was a manufacturer of small garden tractors and other agricultural equipment founded by Herbert C. Roths in Alma, Michigan. The company manufactured Garden King Walking Tractors, BesRo Riding Tractors, and Till Ro Stalk Cutters.

## History

Herbert Carl Roths was born in Edna, Iowa in 1902 and died in St. Louis, Michigan in 1978.both Herbert and his wife are at the Riverview Cemetery in Rock Rapids, Lyon County, Iowa, USA .
At the time of his first patent Herbert Roths was a resident of Alpena, Michigan and the company was in the early stages of startup. With the submission of the second patent, the late Roths had settled into Alma, in Gratiot County, Michigan.
The first patent (D146,947) was applied for by Herbert C. Roths on August 24, 1945 for the design of an ornamental tractor. This patent was awarded on June 17, 1947. At the time of the second patent (D157,432), Herbert C. Roths was an assignor to Roths Industries Inc., Alma, Michigan. The patent was applied for on December 19, 1946 and awarded on February 21, 1950. The second patent was a garden tractor design which would later become the Roths Garden King walking tractor. The first production Garden King walking tractors were sold in late 1945. Over the next few years variations built from the Garden King's parts would become available. The Roths Model-G and BesRo would borrow many production parts from the Garden King, one of which being the transmission. The company was still producing the Terrier Tractor, Country Boy and Little Jeff riding tractors as late as 1960.
Herbert Roths had two patents issued in 1970 and 1973 for a transplanting loader and transplanting machine.

These tractors may have been sold or licensed to a distributing company in 1946/1947, by the name of General Implement. General Implement sold the Garden King labeled as the GI garden tractor.

The fertilizer was sowed in two bands with the seeds planted in-between the fertilizer bands. Roths Industries stated that this eliminated the danger of damaging the seeds during germination.

### Model W & Model R - BesRo

An optional steering assembly with a sulky seat and wheels was available in 1949 to convert the Model W transmission into a riding unit.

This original tricycle design was known as the BesRo Model W and was precursor to the BesRo Model R. The Model R BesRo used four wheels with the drive unit mounted in the rear. The riding frame was attached to the front of the transmission. The BesRo tractor was phased out of production by the mid-1950s and replaced with the Roths Country Boy.
