1. Release over pull system
   Rollover protection system
2. Reverse order plow set
   Real optics plowing system

Safety is an important factor of any modern tractor, and you probably want some kind of rollover protection system, or ROPS, on any tractor you buy. This ensures that if the tractor does take a spill, you don't get crushed when it does so.

1. Locked steering columns
   GPS
2. External sensors
   A compass

GPS is arguably one of the greatest innovations in farming ever. With GPS navigation, a tractor can be set on a perfectly straight path, allowing the farmer to concentrate less on where they're going and more on what they're doing.

1. Front end loader
   Full emergency lever
2. Farm environment lead
   First-ever lean

The front end loader is a kind of tractor attachment that puts a scoop on the front of a tractor so it can push or shovel or lift a load of something. They were actually first designed in Sweden but are pretty common all over the world now.

1. Row crop
   Utility
2. Speciality
   All of the above

John Deere produces tractors in four main categories. Those include utility tractors, row crop tractors, specialty tractors, and the fourth category is four-wheel-drive tractors. Of course, in those four categories, there are numerous variations as well.

1. Wood
   Steel
2. They've always been rubber.
   Tin

Back in the day, most tractors had steel wheels. Often, to improve traction, they'd have bumps and even spikes added to them to help dig into the soil. This also meant they could not be used on roads without destroying them.

1. 12 million
   15 milion
2. 19 million
   26 million

It's a rough number but it's believed that there are in the neighborhood of 26 million tractors currently in operation around the globe at the moment. Over 2 million were sold globally in 2017 alone.

1. Field guides
   Farmhands
2. Rope
   The hood ornament

Most people don't consider how hard driving in a straight line is because roads have guide markings. Tractor drivers in fields used to have to line the hood ornament up with a landmark in the distance to ensure that they were staying on a relatively straight track as they plowed.

1. John Froelich Engineering
   Waterloo Gasoline Engine Company
2. Parr and Hart Farm Supply
   The Dyson Motor Company

In 1918, John Deere bought the Waterloo Gasoline Engine Company which had been producing tractors that went by the name Waterloo Boy tractor since 1911. Word is they didn't sell any for a few years but eventually they became popular. Deere bought them out for over $2 million.

1. To grow crops
   To plant
2. To pull
   To farm

Just like a ton of words in the Engish language, tractor traces its roots to the Latin language. The word "trahere" or "traho" means to pull, drag, or draw. That's why protracted, for instance, means "drawn out." They all come from the same place.

1. Fendt
   Autonomous Tractor Corporation
2. Case IH
   All of the above

A number of manufacturers are looking at the evolution of tractors, including making them entirely autonomous and driverless. Case IH, the Autonomous Tractor Corporation, Fendt and John Deere are all working on models.

1. Seat belts
   Safety roll bar
2. Emergency engine shut off
   Speed limiter

The roll bar was first used in tractors back in 1966. This meant that in the event a tractor tipped over, which actually happens pretty frequently, the driver would still be protected from being crushed under the weight of the tractor.

1. Nothing
   They refused to repossess tractors.
2. They gave away free tractors,
   They offered interest-free loans.

There's no doubt the Depression was a hard time for everyone and farmers were hit harder than many. While many went bankrupt, John Deere refused to repossess the tractors of farmers who couldn't pay them off and instead let them keep doing whatever work they could with the machines.

1. Fendt Vario 1000
   John Deere 4090
2. Case IH Steiger/Quadtrac 620
   Ford Farmall

While all tractors are pretty powerful machines the Case IH Steiger/Quadrac 620 actually outperforms most high-powered sports cars under the hood and features a 692hp engine and a 500-gallon fuel tank.

1. It's an electric tractor.
   It's the world's largest tractor.
2. It's a DIY tractor kit.
   It's the world's most advanced tractor.

The LeTourneau L-2350 is in the Guinness Book of World Records as the absolute biggest tractor in the world. It's used in construction and mining operations to carry massive loads that can reach weights of over 80 tons.

1. Case IH Farmall
   John Deere Super Tracker
2. Cub Cadet Farm Boy
   John Deere Model R

The John Deere Model R was the first diesel-powered tractor that hit the market, and it dates all the way back to 1949. It could haul nearly 7,000 pounds and reach a somewhat unimpressive 11.5 miles per hour in fifth gear.

1. 5 hours
   20 hours
2. 35 hours
   55 hours

There's a reason tractors replaced oxen and horses on farms. The job a tractor can do in one hour could take a team of four horses over 55 hours to do. In fairness, the horses would be doing a harder job with the plow than a tractor would with a disc harrow, but still. The difference is dramatic.

1. Porsche
   Koenigsegg
2. Lamborghini
   Ferrari

Lamborghini designs tractors under the name Lamborghini Trattori. As you might expect, they're still some high-performance vehicles, and they can cost upwards of $146,000 making them at least more affordable than Lamborghini cars.

1. The pulley
   The hitch
2. The drawbar
   The rack

A drawbar is what attaches a tractor to something like a harrow plow or a seed sprayer or whatever it's hauling behind it. For the most part, it's just a long piece of metal that connects to the tractor and the attachment like a tow line but made of solid material.

1. An electric tractor
   A hybrid tractor
2. An ultra-compact tractor
   A DIY tractor kit

GridCON is John Deere's electric tractor model which is still being ironed out in the development phase though it has been shown off a few times. It's said to have an impressive 400 horsepower engine.

1. 285,000
   564,000
2. 603,000
   876,000

Tractor production hit a historical peak in 1951 and 564,000 of them were manufactured that year. It's gone down slowly since then, but that was the year that they were clearly the most important thing any farmer could own.

1. 1925
   1933
2. 1939
   1941

Around about 1932 and 1933 most tractor companies began offering rubber tires as a standard feature on tractors. During the same time period, a number of businesses, like blacksmiths, would offer their services to retrofit steel-wheeled tractors with new rubber ones.

1. England
   Iowa
2. Kansas
   Australia

John Froelich is credited with creating the first fully-functional gasoline-powered tractor that could drive both forwards and backward back in 1892 in Iowa. The word tractor was not in use at that time but it's still clear that's what it was.

1. It was built in 1911.
   It was built in 1895.
2. It was built in 1900.
   It was built in 1903.

The oldest one anyone has in the world right now dates back to 1903. It was built by Charles Hart and Charles Parr, and if you want to see it you actually still can! Currently, it belongs to the Smithsonian Museum.

1. 5
   26
2. 83
   Over 100

Because farmers were just catching on to how useful tractors could be, everyone wanted a piece of the pie. Over 100 companies began producing tractors between 1916 and 1922 though very few of them are still at it today.

1. 87 miles per hour
   95 miles per hour
2. 103 miles per hour
   131 miles per hour

In 2019 a JCB 4000-series Fastrac tractor set a new speed record for tractors by hitting a staggering 103 miles per hour. The record was set in England, beating the previous 87 mph record set just the year before on the show "Top Gear."

1. $785
   $925
2. $1000
   $3500

A high-end tractor back in 1920 might set you back $785, which was a steep investment at the time. Adjusted for inflation that's only about $10,000. By 1922 they would cost less than $400 apiece. High-end tractors today can cost upwards of $150,000.

1. Massey Ferguson
   John Deere
2. Mahindra
   McCormick

Indian tractor manufacturer Mahindra is actually the largest tractor manufacturer in the world, although John Deere has been doing it much longer. The company dominates the Indian market which is the largest in the world and also has facilities in places like Australia and the US.

1. Over 700
   Over 900
2. Over 1,000
   Over 2,000

There are actually several hundred companies that have designed and sold tractors over the years, and though companies like Kubota and Massey Ferguson have designed over 600 kinds of tractors, John Deere leads the pack with over 900 models.

1. CUT
   SUV
2. MRE
   ST

A "normal" tractor can be referred to as a utility tractor and a smaller, more maneuverable version — like a lot of what John Deere sells — are called compact utility tractors or CUTs. These will generally have a smaller frame and perhaps less engine output overall than a full-sized utility tractor.

1. Robots
   AI
2. Self-driving cars
   Tractors

Blue River Technologies was acquired back in 2017 by John Deere because of the work the startup had been doing in AI or artificial intelligence. This is part of John Deere's initiative to produce self-driving tractors.

1. India and China
   The US and China
2. China and Russia
   Russia and India

Millions of tractors are sold every year and about half of them can be found entirely in India and China, the two largest and growing markets for agricultural machinery in the entire world.

1. Ford
   Jeep
2. Fiat
   All of the above

Numerous auto manufacturers have also designed tractors over the years. Jeep only made a few models from the '40s through to the '60s while Ford has designed nearly 200 and Fiat over 100.

1. 1812
   1867
2. 1890
   1903

Richard Trevithick came up with the idea for the barn engine back in 1812. It was a bit of a ways off from what you'd consider a modern tractor. It was essentially a threshing machine outfitted with a steam-powered engine.

1. 100,000 tractors sold
   1 million tractors sold
2. They'd made $1 billion.
   They had facilities in 10 countries.

By 1966 the John Deere Company had cracked its first $1 billion dollars which is a heck of a lot of money no matter what year it is. To give that some perspective, adjusted for inflation that's about $7.9 billion today.

1. Crop King
   Waterloo Boy
2. Dain All-Wheel Drive
   Model R

The Dain All-Wheel-Drive tractor was Deere's first foray into the tractor market after they'd acquired the Dain Manufacturing Company back in 1911. The founder of Dain, now working for Deere, created 100 units of that early design.
