Key takeaways

  • Roths Industries belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Roths Industries to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Roths Industries from memory before moving on to harder problems.

Reference excerpt

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.

Products

Model W - Garden King The Roths Garden King-Model W is a self-propelled two-wheel tractor which was introduced sometime around 1945. The number of units produced remains unknown. According to a March 15, 1949 part list, the 6 H.P. standard Garden King walking tractor and reverse drive with 6x12 tires had a domestic shipping weight of 504 pounds (229 kg), a net weight of 420 lb (191 kg), and a list price of $375.00. Later in 1954 this tractor was listed as $345.00. 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. This may have been a marketing strategy of Roths Industries to reach out to the national agricultural market.

Model G The Garden King Model W was introduced as a high crop walkbehind garden tractor but sometime in 1947 or 1948 the tractor was also available in a lower stance version. This new design came equipped with a new type ratchet differential drive based on the original Model W differential. By 1950 the tractor had become known as the Model G. To steer this type of tractor, the operator did not have to overcome the power in the drive wheels because of the differential design. When the clutch is disengaged the tractor can be easily moved in forward or backward motion. According to a 1950 magazine advertisement, the Model-G walking tractor had a list price of $175.00.

Worked examples

Example 1 — a first encounter with Roths Industries

Start with the simplest possible case. Write down what Roths Industries claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Roths Industries before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Roths Industries ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Roths Industries

In research
Roths Industries appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Roths Industries in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Roths Industries is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture companies of the United States, Lawn and garden tractors, so understanding it makes those chapters shorter.
In everyday life
Look for Roths Industries outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
