More speed selection variety - PowrReverser™ Hi-Lo 24F/12R transmission

Gear shift lever with hi-lo buttons

Overview

Ample speeds and ease of operation for demanding applications with the 24F/12R PowrReverser, providing 24 forward speeds and 12 reverse speeds. This transmission comes standard with a dual speed 540/540 Economy power take-off (PTO), and it is ideal for applications requiring frequent directional changes, such as loader work and PTO work like rotary cutting and baling hay. 

Benefits

• Effortlessly switch directions with a small finger motion using the electrohydraulic fingertip directional lever
• Frees the right-hand to operate other tractor controls, such as the loader, rear implements, or throttle, as the directional lever allows the operator to steer and shift direction with the left-hand
• The control is located on the left side of the instrument console and selects forward, reverse, and neutral positions
• Ideal for rear blading and any applications that require frequent directional changes in tight spaces
• Clutch-less hydraulic shifting between forward and reverse
• Lower engine vibration, reduced noise, less wear and tear on the engine, reduced fuel consumption, and increased operator comfort from the standard economy PTO (E-PTO)

Additional details

The hi/lo selector buttons are located on the gear shift lever for each forward gear and are represented by a rabbit and a turtle, respectively.
 
The forward lever selects one of four gears.  All are synchronized for on-the-go shifting with the use of the clutch. The rear lever selects one of three ranges: A, B, or C. 

24F/12R transmission includes:

• Hydraulic wet clutches (forward and reverse) 
  • 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
• Platform-mounted shift levers (four gears, three ranges) 
  • Two platform-mounted levers offer easy and comfortable shifting for a pleasant operator experience
  • The gearshift lever is easy to reach, and the less-used range lever is shorter. Unique knobs make it easy to distinguish between the two
• Left-hand reverser
• Constant-mesh helical-cut gears
  • Provide quieter operation and excellent reliability while the pressure-lubricated top shaft adds to the transmission durability
  • Fully enclosed, rigid shift linkages for short throw and crisp shifts enable all operators to clearly know in what range and gear they are operating
• Pressure-lubricated top shaft
• Positive park pawl
• Neutral start switch

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 an optional field installed infinitely variable control kit. 

See the PTO functional area for more information on E-PTO. 

Power bulge and torque reserve pull through the tough spots

Power bulge and torque curve

Overview

When the tractor is under load, power bulge and torque rise work together to get through the tough spots without having to   downshift.

As rpm drops, the only way to maintain or increase horsepower is to provide additional torque. Whether bailing wet hay or lifting a heavy load, the additional power allows the tractor to continue performing the job without stopping. The rated economy power take-off (EPTO) speed occurs near the peak torque rise providing power when you need it in PTO applications.     

Benefits

• Increased productivity in demanding conditions with more power when you need it
• More lugging ability for quicker power recovery
• Additional torque provides force to remain horsepower as engine rpm drops below rated speed

Additional Details

Horsepower and torque are mathematically related.

5M 4-Cylinder tractors provide 4% power bulge while 5E 4-Cylinder tractors provide 2% power bulge.

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

PowerTech™ PWL FT4 technology

Overview

All John Deere engines are designed and engineered specifically for agricultural applications. The engine powering 5 Series tractors is EPA certified Tier Level 4.

Benefits

• Efficient and cost-effective operation 
• Allows for greater productivity and ease of operation 
• Responsive power reducing the need to downshift the transmission

Additional details

The U.S. EPA and Environment Canada requires all off-road diesel engines with 18.6 kW (25 hp) or more to meet stringent FT4 emissions regulations.

PowerTech EWL/PSS/PVS engine identification

Several defining features on 5 Series tractors maximize the performance and reliability of the emissions package. A completely shielded DOC/SCR not only protects essential components from damage but 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

Shielded for protection

Diesel oxidation catalyst (DOC) 

Deere has chosen to utilize an exhaust filter (DOC) to reduce particulate material so the engine can operate at a level which produces less nitrogen oxide (NOx). With less NOx created, it requires less DEF 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 at the exact moment needed. 

Diesel exhaust fluid (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 DEF tank keeps the operator 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 engine control unit (ECU)-controlled supply module draws DEF 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 diesel exhaust fluid dosing can begin.

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

Instrument cluster

Power take-off (PTO) target bars

Overview

Operators can view information in a crisp, vibrant, and useful array on the tractor instrument cluster.

Benefits

• Clear and bright indicators, warning lights, and gauges
• Provides operators with crucial onboard diagnostics through the roll-mode function
• Visibility of engine hours, ground speed, Hi-Lo indicator, forward, neutral, and reverse all at the same time
• Light-out indicator for trailer light, turn light, and hazard light bulbs
• Clearly presented PTO target bars to indicate the correct PTO speeds when operating the PTO

Additional details

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

Cooling package design and serviceability

Every utility tractor producer wants to maximize uptime and appreciates enhanced performance. The cooling package on the Final Tier 4 (FT4) 4-cylinder 5E Tractors allows for easier access to and serviceability of certain critical components. This improvement to serviceability will save time and also enhance tractor performance.

The cooling package features a first-pass screen to catch larger debris, a slide-out condenser (only on cab tractors) a charge air cooler that tilts forward, and a hydraulic oil cooler that slides out halfway to both sides of the tractor.

First pass screen

Charge air cooler tilted forward

The engine is equipped with an electronically controlled fan drive, which means that it only runs as fast as the needs of the tractor demand at that time. This is a fuel-saving device which improves hydraulic cooling and reduces the noise level for the operator. It also positively impacts total fluid efficiency.
