Automotive-style light-emitting diode (LED) instrument cluster

Controlling the 5M is easier and brighter than ever before. A fresh new instrument cluster displays information in a crisp, vibrant, and useful array. A larger alternator (OOS: 90 amp, cab: 120 amp) produces plenty of power for internal and external components.

This window into tractor functionality and diagnostics provides ample information. Indicators, warning lights, and even the gauges are clear and bright. The roll-mode function now provides operators with crucial onboard diagnostics. Engine hours, PTO speed, ground speed, hi-lo indicator, forward, neutral, and reverse, are all visible at the same time.  There is a light-out indicator for trailer light, turn light, and hazard light bulbs which is driven by new software. A straightforward layout and sleek design requires no customer interface. When operating the PTO, there are clearly presented PTO target bars to indicate the correct PTO speed.

There are daytime and nighttime modes which are based on the position of the light switch. The mode actually adjusts the backlight levels of the display for optimum visibility.

16F/16R PowrReverser™ transmission

The PowrReverser transmission provides 16F/16R speeds and can be equipped with the factory-installed high/low creeper. This transmission comes standard with a dual-speed 540/540 Economy power take-off (PTO), and is ideal for applications requiring frequent directional changes.

Hydraulic wet forward and reverse clutches maximize durability and outlast the life of any dry clutch. When tractors are run by multiple operators with a variety of experience levels, a wet clutch is the best way to maintain transmission integrity and performance while decreasing clutch replacement costs.

Two platform-mounted levers offer easy and comfortable shifting for a pleasant operator experience. The gear-shift lever is easy to reach and the less-used range lever is shorter. Unique knobs make it easy to distinguish between the two. Also incorporated into the gear-shift lever is the declutch button. No foot clutching required to shift between gears within a range.

The forward lever selects one of four speeds, all synchronized shifts for on-the-go shifting with the use of the clutch. The rear 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 of the way to B without stopping. There is a separate lever for creeper operation.

Maximum productivity is achieved with clutchless hydraulic shifting between forward and reverse and is ideal for loader work and any other applications that require frequent directional switches in tight spaces. An electrohydraulic fingertip directional lever control allows the operator to effortlessly switch directions with a small finger motion. The control is located on the left side of the instrument console and selects forward, reverse, and neutral positions. It also allows the operator to steer and shift direction with the left hand, freeing the right hand to operate other tractor controls, such as the loader, rear implements, or hand throttle. The PowrReverser™ has a built-in engagement override valve for additional safety. This valve requires the clutch pedal to be depressed one time after each engine start before the transmission will begin to operate normally, giving the operator another opportunity to put all focus on the tractor.

**A neutral start switch requires the directional lever be in the neutral position to start the engine.**

The speed of directional changes can be adjusted to the operator's preference or application demands with the field-installed infinitely variable control kit.

16F/16R transmission includes:

• Wet clutch
• Platform-mounted shift levers (4 gears, 4 ranges)
• Declutch button integrated into gear-shift lever
• Left-hand reverser
• Constant-mesh helical-cut gears
• Pressure-lubricated top shaft
• Positive park pawl
• Neutral start switch

All tractors have E-PTO (a fuel saving feature) that allows customers to operate rear implements at 540 PTO rpm but at lower engine rpm. The result is lower engine vibration, reduced noise, less wear and tear on the engine, reduced fuel consumption and increased operator comfort.

**See PTO Functional area for more information on EPTO**

32F/16R PowrReverser™ transmission for ultimate speed control

For operators requiring more field speeds to achieve the most precise operating ranges, as well as for quickly moving from task to task with transport speeds of up to 40.23 km/h (25 mph), the 32F/16R PowrReverser™ Plus transmission is the ideal choice.  This transmission provides 32F/16R speeds for the ultimate in speed selection. Convenient push-button controls actuate the electrohydraulic high/low selector. Also incorporated into the gear shift lever is the declutch button. No foot clutching is required to shift between gears within a range.

The gear lever selects one of four speeds, all synchronized shifts for on-the-go shifting with the use of the clutch. This same lever is where the high/low control buttons are located. The rear lever selects ranges A, B, C, or D. Ranges C and D are fully synchronized. That means, when upshifting, operators can move from ranges B to C to D without stopping the tractor. On the downshift, operators can move from D back down to C without stopping. 

The high/low feature benefits operators who frequently transport their tractors from field to field or find themselves in bog-down situations during rear power take-off (PTO) work. Customers can push the rabbit button (high) without having to depress the clutch to get a 20 percent increase in speed. They can also push the turtle button (low) to get a 20 percent decrease in speed, similar to downshifting or engine braking without having to grab another gear. The 32F/16R transmission includes the infinitely variable shuttle control feature.  The PowrReverser™ has a built-in engagement override valve for additional safety. This valve requires the clutch pedal to be depressed one time after each engine start before the transmission will begin to operate normally, giving the operator another opportunity to put all focus on the tractor.

NOTE: A neutral start switch requires the directional lever be in the neutral position to start the engine.

32F/16R transmission includes:

• Wet clutch
• Declutch button
• Platform-mounted shift levers (four gears, four ranges, with hi/lo selector)
• Left-hand reverser (F to R without clutching)
• Constant-mesh, helical gears
• Pressure-lubricated top shaft
• Positive park paw
• Neutral start switch

All 5M Tractors have E-PTO (a fuel-saving feature) that allows customers to operate rear implements at 540 PTO rpm but at lower engine rpm. The result is lower engine vibration, reduced noise, less wear and tear on the engine, reduced fuel consumption and increased operator comfort.

Heavy-duty 3-point hitch lift capacity for implement versatility

Overview

A Category 2, 3-point hitch on 5M Tractors provides the lift capacity and compatibility to perform in a variety of different applications. The 3-point hitch adapts to a wide variety of implements and has plenty of lift capacity to handle heavy implements such as planters, sprayers, and field cultivators.

Benefits

• With the choice of either mechanical or electrohydraulic hitch controls, hooking up implements is convenient with telescoping draft links, adjustable sway bars, and interchangeable hitch balls.
• Both mechanical and electrohydraulic hitch controls have a depth stop for consistency when lowering the hitch. Each time the position control lever is pushed forward, it stops where the depth stop has been positioned.
• Optional larger cylinders are available for increased lift capacity:
  • PowrReverser™ transmission models: 65-mm (2.56-in.) cylinders in base with electrohydraulic hitch lift capacity of 2340 kg (5159 lb); option of one 65-mm (2.56-in.) and one 75-mm (2.95-in.) lift cylinder (averaging to 70 mm [2.75 in.]) which provides electrohydraulic hitch lift capacity of 2701 kg (5955 lb)
  • PowrQuad™ PLUS and Powr8™ transmission models: 75-mm (2.95-in.) cylinders in base with hitch lift capacity of 3164 kg (6975 lb); option of 80-mm (3.15-in.) cylinders with hitch lift capacity of 3569 kg (7868 lb)

Additional details

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.

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.

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.

Power bulge and torque reserve pull through the tough spots

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.

Heavy base tractor weight for stability

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.

EPA Final Tier 4 (FT4) compliant engines with maximum fluid efficiency

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.

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.

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.
