5085M Utility Tractor

The U.S. Environmental Protection Agency and Environment Canada requires all off-road diesel engines with 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 130 psi (900 kPa, 9 bar) 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 into 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 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 is capable of meeting 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.

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.

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.

The forward 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. 

High/Low selector on gear lever

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.

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

32F/16R transmission includes:

• Wet clutch
• 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.

**See PTO Functional area for more information on E-PTO**

A Category 2, 3-point hitch on 5M Tractors provides the lift capacity and compatibility to perform in a variety of different applications. The customer has 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 in base equipment. Both mechanical and electrohydraulic hitch controls have a depth stop. This feature provides consistency when lowering the hitch. Each time the position control lever is pushed forward, it stops where the depth stop has been positioned. This is valuable to anyone who desires a consistent, level ground, like when preparing a seedbed.

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. The 53-mm (2-in.) external cylinders provide for a hitch lift capacity of 2174 kg (4793 lb) at 610-mm (24 in.) behind the hitch-lift balls.

5M 3-point hitch

5115M Tractors come equipped with 63-mm (2.5-in.) lift cylinders which provide for 2692 kg (5935 lb) of lift capacity at 610-mm (24-in.) behind the hitch-lift balls. Any 5M Series Tractor has the option of selecting these larger lift cylinders through the factory or a field-installed heavy-duty hitch kit.

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.

The exclusive mid-frame design on the 5M Series offers additional strength and durability but also reduces noise and vibration. Because the mid frames are made from hardened cast steel they provide the tractor strength and stability even in the toughest conditions.

The mid frames also support and protect different pieces of essential equipment. The hydraulic pump, located between the mid-frames, is attached to the transmission for short hydraulic lines and simplified fluid flows. An optional mid-mount fuel tank allows the tractor to carry an extra 9 gal. (34L) on cab tractors and an extra 7.8 gal. (29.5L) on OOS tractors. This is especially useful for long days in the field or when a trip to fill up with diesel may not be convenient.

The mid frames are compatible with current loader mounting frames, which is beneficial for those interested in upgrading their tractors and keeping their H-Series Loaders.

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 in regards to 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.
