Integrated declutch and gear buttons on transmission control lever

The ergonomically placed transmission control allows the operator to change gears and ranging with one simple control. Ranges on the transmission control can be selected by moving the controller in an H pattern. The lever selects ranges A, B, C, or D. Ranges C and D are fully synchronized. That means when upshifting, operators can move from range C to D without stopping the tractor. On the downshift, operators can move from D all the way to B without stopping

• PowrQuad PLUS transmission can be ordered 16 forward speeds and 16 reverse speeds with four manually shifted ranges and four electronically shifted speeds in each range.
• Powr8 transmission can be ordered 32 forward speeds and 16 reverse speeds with four manually shifted ranges and eight electronically shifted speeds in each range. Additionally, ECO Shift offers a top speed of 40 km/h (25 mph) with reduced engine rpm in the two highest gears.
• Two buttons (a rabbit or turtle indicator) allow operators to gear up (rabbit) or gear down (turtle) within a range.
• A range change can be made with a simple press of the declutch button rather than using the foot clutch.
• Eliminates wear on the clutch
• Reduces steps to change gears by 35 percent, resulting in improved efficiencies

PowrQuad PLUS and Powr8 transmissions offer great value for producers looking for a more productive transmission in a mid-spec utility tractor.

Adjustable sway bars and telescoping draft links can be easily adjusted to adapt to a wide variety of implements. The right lift link also adjusts without tools for added convenience when leveling implements.

5M rear fender hitch controls

Operators do not need to carry a tool to adjust the rear hitch. Operators can also raise and lower the 3-point hitch from outside of the tractor with the conveniently located rear fender hitch controls.

Rear quick hitch

An updated three-point quick hitch is offered on the 5M Tractors.

• This updated design is a break from the existing welded quick hitch as the frame is cast.
• The curved design eliminates the potential for contact with the rear fender and extensions.
• The quick hitch is available as a field kit option.

As rpm drops, the only way to maintain or increase horsepower is to provide additional torque. The output horsepower is greater than or equal to rated horsepower as the engine is pulled down to 1750 rpm.

The peak torque rise also occurs near the rated economy power take-off (EPTO) speed.

5M power curve summary

5M torque curve summary

A heavy tractor means more down force to keep implements in the ground. More weight also leads to improved traction and performance in the field. Because the 5M is made with heavy and durable cast steel, it weighs enough to power through those tough jobs.

The compactness of the 5M Series regarding wheelbase, weight, and total height tractor makes this tractor suited for a variety of different applications and is the perfect choice for all types of farms.

A heavy tractor also means better stability when performing loader work. Transport full bucket loads faster and lift bales higher with a stronger and more stable base.

Tractor weight package

The U.S. Environmental Protection Agency (EPA) and Environment Canada requires all off-road diesel engines with 18.6 kW (25 hp) or more to meet stringent FT4 emissions regulations. John Deere uses the most efficient and cost-effective solution for the tractor package to meet emissions requirements at each horsepower level. The 5M delivers a hassle-free emissions solution that allows faster work and operation with ease.

The engine powering the 5M is EPA certified Tier Level 4. This is achieved through a combination of a diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR) using diesel exhaust fluid (DEF, or urea).

Several defining features on the 5M maximize the performance and reliability of the emissions package. A completely shielded DOC/SCR not only protects essential components from damage, it also keeps out dirt and debris. The well-packaged and tightly organized circulation system means there is more room to work around the tractor.

PowerTech™ PWL Final Tier 4 technology

Key components of the emissions system include:

DOC

John Deere has chosen to utilize an exhaust filter to reduce particulate material so the engine can operate at a level which produces less NOx. With less NOx created, less DEF is required to treat. The result is improved total fluid economy (diesel and DEF).

The engine is programmed to aggressively respond to changes in power needs, which can temporarily increase particulate matter. Since the exhaust filter removes particulate matter instead of the engine, the engine is left free to do what it is designed to do – deliver all of the power, torque, plus transient response needed.

DEF

DEF is an ISO 22241 standard aqueous urea solution consisting of 32.5 percent urea and has a freezing point of -11°C (12°F). A heated DEF tank keeps the customer in the field longer even when the temperatures drop below freezing. The DEF tank header is integrated with a temperature sensor, and plumbed engine coolant lines are used to promote thawing and prevent freezing in the tank during operation.

DEF tank

Mounted near the DEF tank, the electronic control unit (ECU)-controlled supply module draws diesel exhaust fluid from the storage tank and provides a pressurized flow to the dosing module. When the ignition key is off, the supply module pump will reverse direction to return any accumulated fluid back to the tank. The supply module is also fitted with a replaceable filter to prevent contaminants from entering the dosing lines. Both the supply module and dosing lines are electrically heated and controlled by the ECU to determine when DEF dosing can begin.

The dosing module is cooled by engine coolant and used to inject DEF at a pressure of 9 bar (900 kPa, 130 psi) into the decomposition tube. A harness is connected to the dosing valve that relays the needed DEF to inject based upon the amount of NOx exiting the DOC measured from the NOx tube sensor.

The decomposition tube is the internal mixing device used to circulate DEF with engine exhaust prior to entering the SCR/AOC after-treatment device.

SCR

To reduce the NOx, DEF is injected into the exhaust stream. When the exhaust gases combine with the DEF in the SCR catalyst, the NOx is broken down into nitrogen and water vapor.

Exhaust gas recirculation (EGR)

EGR reduces the high temperatures where these compounds are formed in the engine cylinders by replacing excess oxygen with a prescribed amount of cooled exhaust gas.

Exhaust gases contain more carbon dioxide than oxygen. The EGR valve, in conjunction with the venturi tube, and engine control unit (ECU), allow a controlled amount of exhaust gas to enter the intake manifold to mix with the incoming fresh air.

Replacing excess oxygen with cooled exhaust gas leads to:

• Lower combustion temperatures, creating less NOx.

In addition, EGR allows for:

• Advanced timing
• Optimal engine performance
• Maximum fuel economy

For added performance and efficiency, the engine passes the exhaust gases through an EGR cooler before it enters the engine.

Exhaust airflow enters the EGR cooler from the exhaust manifold near the turbocharger. Based on engine load, air temperatures, and rpm, the ECU opens or closes the EGR valve, allowing a measured percentage of exhaust gas to enter the intake manifold. The gases mix with the rest of the incoming air from the turbocharger and aftercooler before entering the cylinders.

Series turbochargers

The PowerTech PWL 4.5L (274.6-cu in.) engine utilizes one turbocharger — a fixed geometry turbocharger. Fresh air is first drawn into the low-pressure fixed geometry turbocharger and compressed to a higher pressure. The compressed air is then routed to the charge air cooler and then to the intake manifold.

Benefits of air-to-air aftercooling

• Lowers the intake manifold air temperature
• Provides more efficient cooling while reducing temperatures for greater engine reliability
• Higher volume of air flows into the cylinders
• Engine can meet the increasing horsepower demands

Combustion process with externally cooled EGR

Functions: 

• According to engine operating conditions, the recirculated exhaust gases reduce the oxygen portion in the intake air to approximately 20 percent. Without any increase of the charge air pressure, the oxygen rate is not high enough to ensure a complete combustion of the fuel injected at high engine loads.

Advantages:

• Fuel-efficient combustion is achieved because sufficient oxygen is provided.

A restrained, cooler combustion is realized, since the typical hot combustion process, which is generated by an oxygen surplus, is dampened by the inert exhaust gases. Hence, NOx emissions are reduced.
