Reference excerpt

John Deere 3020 is a tractor that was manufactured by John Deere as part of its New Generation series from 1964 to 1972. The 3020 is nearly identical to the John Deere 3010 model that it replaced. It has a wheelbase of 90 inches, and a fuel capacity of 29 gallons. It was offered with three different engine options including a 3.7L 4-cyl gasoline engine, a 4.4L 4-cyl diesel and a 3.7L 4-cyl LP gas engine all produced by John Deere. The 3020 was rated at 71 horsepower. Transmission options included the standard Synchro Range transmission that offered 8 forward speeds and two reverse speeds and an optional eight speed power shift transmission. Several different tread options were offered by John Deere on the 3020 including, standard, narrow front Row Crop, narrow front Row Crop with "Roll-O-Matic", wide front Row Crop, Row Crop Utility. and Orchard. During its production run a few minor changes were made to the 3020 and other tractors of the New Generation series. These included moving the hydraulic levers from the left side of the dash to a console to the right of the operator, moving the PTO lever from the right side of the dash to the left, a narrower oval muffler for improved visibility, and a longer, bent, gear shift lever. Some factory options available on the 3020 included hydraulic front wheel assist, a Roll Gard, roll over protective structure, a steel canopy that bolted to the Roll Gard. An enclosed cab with heat and air conditioning was also available as an extra cost option. From 1964 to 1969 John Deere also produced an industrial variant of the 3020. It was painted yellow instead of green and was known as the John Deere 500.

Worked examples

Example 1 — a first encounter with John Deere 3020

Start with the simplest possible case. Write down what John Deere 3020 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 John Deere 3020 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 John Deere 3020 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 John Deere 3020

In research: John Deere 3020 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 John Deere 3020 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: John Deere 3020 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture stubs, John Deere tractors, Vehicles discontinued in 1972, so understanding it makes those chapters shorter.
In everyday life: Look for John Deere 3020 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.
