John Deere 455 Key Specifications and Features

Engine

Yanmar 3TNA72UJ3, 3-cylinder liquid-cooled diesel, 22 HP max power at 3350 rpm.

The heart of the John Deere 455 is its engine, and it’s a beast in its own right.

It’s equipped with a diesel engine, which is known for its durability and efficiency.

These engines come in both 6 – cylinder and 4 – cylinder options, with power outputs ranging from a minimum of 63 kW (85.656 hp) to a maximum of 149 kW (202.584 hp).

They use high – pressure common rail (HPCR) fuel systems, which provide precise fuel injection, resulting in better fuel efficiency and reduced emissions.

The engine’s design also includes a fixed geometry turbocharger, which helps to boost power and improve performance at various operating conditions.

Another example is the 4045AFM85 engine, which is a 4 – cylinder, turbocharged, and common – rail engine.

It has an output power ranging from 119 kW (161.8 hp) to 168 kW (228.4 hp).

It operates at different engine speeds, such as 2,300 rpm, 2,400 rpm, 2,500 rpm, and 2,600 rpm, with corresponding fuel consumption rates of 33 l/h, 37 l/h, 44 l/h, and 49 l/h.

The engine’s bore is 107 mm (4.2 in) and the stroke is 127 mm (5 in), giving it a good balance between power and efficiency.

Transmission

Shaft-driven hydrostatic transmission with Tuff Torq K91 transaxle, providing infinite forward and reverse speeds for smooth and precise maneuvering.

The John Deere 455 typically comes equipped with a hydrostatic transmission.

This type of transmission is highly popular in compact tractors like the 455 because of its simplicity and ease of use.

Unlike traditional manual transmissions that require shifting gears, a hydrostatic transmission allows for infinitely variable speed control.

This means you can smoothly adjust the speed of the machine without any jerky transitions.

Whether you need to move at a slow pace for precise work or speed up for covering larger areas, the hydrostatic transmission can handle it all.

Hydraulics

Gerotor hydraulic system with 69 bar (1000 psi) pressure and 4.65 gallons per minute flow, supporting efficient operation of attachments.

The John Deere 455 features a robust hydraulic system that consists of a hydraulic pump, hydraulic valves, and hydraulic cylinders.

The hydraulic pump is driven by the engine and is responsible for generating the hydraulic pressure needed to operate the various hydraulic functions.

The hydraulic valves control the flow of hydraulic fluid to the different components, allowing you to operate the attachments with precision.

The hydraulic cylinders, on the other hand, convert the hydraulic energy into mechanical force, which is used to lift, push, or pull.

Dimensions and Capacity

Wheelbase: 50.4 inches (2WD) / 49.4 inches (AWS)

Length: 75 inches

Width: 48 inches

Height: 51.2 inches (without cab)

Weight: Ranges from 965 to 1060 pounds depending on configuration.

Tires: Typically equipped with 18×8.50-8 front and 26×12.00-12 rear lawn/turf tires.

PTO: Independent rear PTO (optional) and mid PTO with electro-hydraulic clutch for versatile implement use.

Build: Solid steel frame and shaft-driven mower deck and PTO for durability and reduced maintenance compared to belt-driven systems.

The John Deere 455 is designed with practical dimensions to ensure it can navigate various work environments.

In terms of transport dimensions, for example, the transport width can be as low as 15 feet 2 inches, and the transport height is around 6 feet 11 inches.

The total length varies depending on the specific model, ranging from 22 feet to 27 feet.

These dimensions make it relatively easy to transport the machine on the road without requiring special permits in most cases.

When it comes to capacity, the John Deere 455 is impressive.

It can handle large volumes of materials.

For instance, in the case of a 24 – foot model, it can hold up to 70 bushels of pure grain or 85 bushels of grain and fertilizer.

As the model size increases to 35 feet, the capacity goes up to 98 bushels of pure grain and 119 bushels of grain and fertilizer.

This high capacity means that the machine can work for longer periods without needing frequent refills, increasing productivity.

Cutting System

One of the standout features of the John Deere 455 is its cutting system.

It’s like a finely tuned surgical instrument for the lawn.

The machine typically comes with a high – quality deck that is made from durable materials, such as heavy – duty steel.

This ensures that the deck can withstand the rigors of daily use and resist damage from rocks, branches, and other debris.

Operating Mechanism

The John Deere 455 uses a slot – type seed metering system.

This system is designed to ensure that seeds are distributed evenly and accurately across the field.

The number of openers (which are used to create furrows for planting) can vary, with options like 30, 40, and 50 openers.

The more openers the machine has, the wider the area it can cover in a single pass, which is especially useful for large – scale farming operations.

The machine’s operation is also supported by advanced technology.

For example, some models may come with electronic controls that allow for precise adjustment of planting depth, seed spacing, and other parameters.

This level of control ensures that the machine can adapt to different soil conditions and crop requirements, leading to better crop yields.

Durability and Maintenance

John Deere is known for its durable equipment, and the John Deere 455 is no exception.

The machine is built with high – quality materials and components that can withstand the rigors of daily use in the field.

The engine, for instance, is designed to have a long service life, with features like efficient lubrication and cooling systems.

In terms of maintenance, the John Deere 455 is relatively easy to maintain.

Regular maintenance tasks include checking and changing the engine oil, cleaning the air filter, and inspecting the seed metering system.

The operator’s manual, which is available for purchase, provides detailed instructions on how to perform these maintenance tasks.

By following the recommended maintenance schedule, you can ensure that the machine continues to operate at its best for years to come.

Conclusion

The John Deere 455 is a well – rounded machine that offers a combination of power, capacity, and precision.

Its diesel engine provides reliable power, while its large capacity and advanced operating mechanism make it suitable for a wide range of farming and agricultural applications.

Whether you’re a small – scale farmer or a large – scale agricultural operator, the John Deere 455 is a machine that can meet your needs.

With its durability and ease of maintenance, it’s an investment that can pay off in the long run.

So, if you’re in the market for a high – performance agricultural machine, the John Deere 455 is definitely worth considering.
