List of John Deere tractors

The Deere company briefly experimented with building its own tractor models, the most successful of which was the Dain all-wheel drive.

The Dain all-wheel drive was the first tractor produced by John Deere, and had only a single rear wheel.

Solid rubber tires were added, and engineers fitted a 28 tooth sprocket to the final drive, giving a road speed of 4 mph (6 km/h).

[4] On June 20, 1928, the model designation was changed from "C" to "GP", to avoid confusion with the "D" when dealers were phoning in orders to the factory.

The tricycle wheel design, patterned after that of the Farmall tractor, reduced steering effort, and greatly increased maneuverability.

The un-styled tractors launched Deere & Company into the row crop farming market which they are still a major part of today.

Dreyfuss learned to operate the tractors, and worked with them in the field to gain firsthand knowledge of the changes that needed to be made.

Dreyfuss and the Waterloo engineers perfected the styled design that was used on all John Deere tractors, with only minor changes through to 1959.

1947, all models operator platforms were updated with, a cushioned seat, new steering column, lights, battery, and electric starting which resulted in an inclosed flywheel.

A pump powered by the PTO clutch provided 1,800 psi (12 MPa) of hydraulic pressure to a lever controlled valve.

This provided sufficient cold weather starting aids for the diesel engine that it would reliably run in sub-zero[clarification needed] conditions.

The live PTO was directed through two 45° bevel gears that proved too small to durably transmit the full torque of the engine.

The tractor was fully serviceable at pulling larger equipment efficiently on large area wheat-land farms.

The 80 also corrected the other design flaws within the R, such as using a water pump and radiator pressure cap, and the addition of a center crankshaft main bearing.

In October 1959, the company showcased a new large 215 hp (160 kW) four-wheel drive (4WD), called the 8010, on the Robert Ottilie Seed Farm north of Marshalltown, Iowa.

To introduce its new generation tractors to all of its dealers in a single day, Deere & Company chartered airplanes to fly more than 5,000 people to Dallas, Texas, on August 30, 1961.

Deere & Company put their new tractors on display outside the Cotton Bowl, and inside Neiman Marcus.

Deere recommended that all tractors include this safety feature, and offered to share its design and test data with its competitors.

The WA-14 and WA-17 were articulated four-wheel-drive tractors, built by Wagner under a no compete clause, which extended to 5 years after deere dropped the line.

The John Deere 4000 was also an economy tractor, providing the same horsepower as the 4020, with fewer features and smaller rear axles.

This innovative cab was isolated from the tractor by large rubber bushings, which dampened vibrations, and the interior was insulated with foam to reduce noise, and protect the operator from extreme temperatures outside.

A foam pad on the firewall and sheets of lead under the dash greatly reduced engine noise inside the cab.

The door post was in line with the exhaust and air intake pipes, which route through the hood for the best forward visibility possible.

Fully integrated heating and air conditioning was standard equipment, and it also featured windshield wipers, a dome light, a red interior lamp to illuminate the gear shift levers and hydraulic controls during nighttime operation, and speakers for an optional AM/FM radio, which many farmers added because they found the cab so quiet they could actually hear it.

The Deere & Company annual dealer meeting was held in Omaha, Nebraska; the launches included: In 2007, Deere & Company released thirty-two (32) new tractor models; the year began with the introduction of the 5603 and 5625, both these are 82 hp (61 kW), and are a further extension of the 5003 and 5025 Series tractors.

But the real announcement came with John Deere introducing a new worldwide numbering scheme for the entire range of compact and agricultural tractors.

These tractors were introduced at the annual Deere & Company dealer meeting; this year's event was held in Denver, Colorado.

ProMagazine.com reports that this pair is for house owners who want a tractor that could take on everyday jobs, some features are: diesel engine, twin touch pedals, hydrostatic transmission, standard 4WD, optional cruise control, power steering, a power take-off (PTO) that is electronically engaged.

Other improvements engineered into these tractors are JDLink, ActiveCommand Steering (ACS), Infinitely Variable Transmission (IVT) AutoMode, GS3 CommandCenter, and the StarFire 3000 receiver.

In a 2010 October meeting in Florida, John Deere dealers were shown the new 1023E and 1026E sub compact tractors that the company announced in February 2011.
