20 Interesting Facts you may not know about John Deere Diesel Engines

Feb 23, 2021

John Deere & Company has a long history of providing quality diesel engines to its customers, from its first in 1949 to today’s Tier 4 PowerTech engine. Throughout this period of time, there have been several exciting developments that have helped shape not just the evolution of diesel engines, but also John Deere history as a whole. Let’s take a look at 20 interesting facts that you may not know about John Deere diesel engines!

Fun Facts About John Deere Diesel Engines

Since 1949, Deere has designed and manufactured diesel engines.
The first Deere diesel engine, found in the Model R, produced 51 horsepower and was the first to offer a live power take-off (PTO) with its own clutch.

The innovative design of the John Deere Model R tractor featured two engines—the 416-cubic inch diesel-fired engine and a two-cylinder, gasoline-fired starter engine. The dual engines resolved certain difficulties often associated with starting diesel engines. Firstly, operators could start the engine with the pull of a lever, rather than manually turning the flywheel. Additionally, they had the capacity to warm-up the engine quickly in cold temperatures.
In 1953, Deere launched the Model 70, the first John Deere diesel-powered row-crop tractor.

In 1959, the model 8010 paved the way for a line of 4- or 6-cylinder diesel engines, as Deere moved away from 2-cylinder engines at the end of 1958.
In 1960, John Deere introduced the 300 and 400 Series engines—its first-in-line 4- and 6-cylinder gasoline, LP gas, and diesel engines—in the model 1010, 2010, 3010, and 4010 tractors.
In 1969, Deere introduced its first turbocharged diesel engine in its 4520 row-crop tractors.
In 1996, Deere rolled out a new breed of engines, called PowerTech™, to comply with Tier 1 standards. Since then, the company has followed a building-block approach to meeting each new regulatory Tier, systematically adopting technologies for the PowerTech platform.
John Deere diesel engines range from 49 to 600 HP.
John Deere has produced more than 5 million diesel engines.
Deere diesel engines can be serviced at any of their 4,000+ service locations worldwide.
John Deere diesel engines are produced for agriculture, construction, forestry, mining, generator drives, marine equipment, and thousands of other applications around the world.

John Deere has been producing diesel marine engines for more than 30 years.
The 8010 produced a significant amount of power for its time – the 1960s – with 215 horsepower.
The John Deere 300 series included the company’s first diesel-powered lawn and garden tractor.

Video: Wheat Yields in USA and China Threatened by Heat Waves Breaking Enzymes

A new peer reviewed study looks at the generally unrecognized risk of heat waves surpassing the threshold for enzyme damage in wheat.

Most studies that look at crop failure in the main food growing regions (breadbaskets of the planet) look at temperatures and droughts in the historical records to assess present day risk. Since the climate system has changed, these historical based risk analysis studies underestimate the present-day risks.

What this new research study does is generate an ensemble of plausible scenarios for the present climate in terms of temperatures and precipitation, and looks at how many of these plausible scenarios exceed the enzyme-breaking temperature of 32.8 C for wheat, and exceed the high stress yield reducing temperature of 27.8 C for wheat. Also, the study considers the possibility of a compounded failure with heat waves in both regions simultaneously, this greatly reducing global wheat supply and causing severe shortages.

Results show that the likelihood (risk) of wheat crop failure with a one-in-hundred likelihood in 1981 has in today’s climate become increased by 16x in the USA winter wheat crop (to one-in-six) and by 6x in northeast China (to one-in-sixteen).

The risks determined in this new paper are much greater than that obtained in previous work that determines risk by analyzing historical climate patterns.

Clearly, since the climate system is rapidly changing, we cannot assume stationarity and calculate risk probabilities like we did traditionally before.

We are essentially on a new planet, with a new climate regime, and have to understand that everything is different now.
