History of Challenger Tractors
Challenger is a leading brand of agricultural machinery owned by AGCO Corporation. AGCO Corporation was founded in 1990 and currently offers a wide product line of tractors, combines, forage equipment, self-propelled sprayers and fertilizer spreaders, tillage machines, attachments and original spare parts.
The entire range of Challenger equipment supplied to the markets of Eastern Europe, Africa and the Middle East is manufactured in AGCO's own factories located around the world. These are modern industrial enterprises, equipped with the best equipment, which makes it possible to produce the most reliable, durable and economical machines.
The Challenger brand began in 1987 when Caterpillar began making tracked tractors. Since then, the range of Challenger-branded equipment has significantly expanded and has been supplemented with wheeled tractors, combines, forage equipment, self-propelled sprayers and fertilizer spreaders, tillage implements and attachments. Each piece of equipment has a long history of success.
The Challenger brand brings together the best models of agricultural machinery that can satisfy the needs of both small farms and large agro-industrial holdings.
With a rich history and decades of experience, the Challenger brand continues to expand. Today it brings together a complete range of modern and high-performance agricultural equipment. Many Challenger models are equipped with fully integrated Autoguide, telemetry, and GTA farm management systems, which allows for even more efficient farm operations.
Challenger's goal is to partner with farmers and growers around the world to help them increase the efficiency, productivity and profitability of their businesses.
The Challenger MT500D wheeled tractor is a range of tractors that deliver optimum performance and productivity thanks to automatic steering systems.
The MT500D Series tractors are equipped with 6.6L and 7.4L AGCO POWER ™ engines, delivering power and torque over a wide range of engine speeds. Engine operation in the low-speed range of the crankshaft helps to reduce fuel consumption, wear, noise, and also allows to increase service intervals.
The hinged hood provides excellent access to the engine compartment for servicing, and the air filter can be changed from the ground.
Challenger's Electronic Engine Management (EEM) controls the engine's workflow, regulates fuel delivery (Common Rail), and ensures quick response to changing loads.
Four-valve technology per cylinder ensures complete combustion, and the opposed intake and exhaust ports of the cylinder head guarantee optimum combustion. The viscous cooling fan maintains engine operating temperature with minimal power loss by monitoring the change in coolant temperature.
The AutoPower VI ™ transmission is simple in design, easy to operate and highly efficient. To avoid power losses, only three multi-plate clutches are used to change all gears and modes.
The transmission control lever combines three functions to allow the operator to disengage the clutch, change direction of travel and change gears.
The speed optimization function automatically selects the range and gear that best suits the actual speed and load.
The AutoPower VI ™ transmission allows operators to select the desired control mode based on their preference or operating conditions. Shifting under load is smooth, easy, and efficient.
An exceptionally strong yet lightweight frame plays a key role in achieving the power-to-weight ratio of the Challenger MT500D Series tractors, which improves productivity while reducing fuel consumption.
Heavy-duty frame joists extend from the front axle mounting plate to the mounting plate behind the engine. The result is a long wheelbase, which increases tractive effort and therefore provides high tractor performance.
Strong and rigid beams provide reliable support for front loader, front linkage and other attachments.
Challenger's optional AutoGuide ™ automatic steering system dramatically improves productivity while reducing fuel consumption, labor and machine wear. The increased accuracy provided by the system reduces the cost of seeds, fertilizers and chemical protection.
