Tractor models and horsepower

Overview

All John Deere 6E Series Tractors feature the reliable and proven 4.5L (275-cu in.) engines. These engines deliver constant power over a wide range of rpm with a power bulge above rated power and excellent torque characteristics.

The 6E Series, while being value-featured and competitively priced, are built with John Deere's long-standing reputation for reliability, durability, and maintainability.

Rated engine horsepower ratings are included for reference to competitor's gross or engine-only power ratings. There are several ratings systems used by other manufacturers. John Deere uses the horsepower-rating standard 97/68/EC, which is widely used in Europe for various regulations.

How is engine-only rated and maximum power determined?

John Deere engineering uses a precise procedure to measure engine-only power levels. The 97/68/EC standard is required in the European Union (EU) as an emission test, so there is some relation to the power a tractor has as a whole functioning unit; however, the procedure requires only that a production engine and radiator are used on a dynamometer test. Use the 97/68/EC horsepower ratings in the above chart to compare to competitor claims of engine-only power.

Benefits of PTO power and power bulge

The John Deere exclusive single-injector control, electronic fuel injection system, and other key engine parts work together to sense engine load and instantly respond as needed to pull through tough spots. This reduces engine rpm fluctuation, resulting in the reduced need to downshift the transmission. Fewer shifts result in fewer ground variations, providing more overall tractor productivity.

To match the engine power characteristics and improve economy of operation, the rated engine speed is 2200 rpm.

Feature and benefit overview

High-pressure common rail fuel system

• Higher injection pressures (up to 1896 bar [27,500 psi]), precise variable injection pressure, variable timing control, multiple injections

Four-valve cylinder head

• Crossflow head design provides excellent breathing from a lower-cost four-valve cylinder head.

Turbocharged

• In turbocharged engines, the air is pre-compressed. Due to the higher pressure, more air is supplied into the combustion chamber, allowing a corresponding increase in fuel injection which results in greater engine output.

Turbochargers

• Precisely matched to the power level and application, the 6Es are equipped with a wastegate (to divert exhaust gases) turbo.

Air-to-air intercooling

• This is most efficient method of cooling intake air to help reduce engine emissions while maintaining low speed torque, transient response time, and peak torque. It enables the engine to meet emission requirements with better fuel economy and the lowest installed costs.

Overview

The 6E Series PowrReverser transmissions deliver unmatched performance. This transmission is ideal for working in tight areas where forward to reverse shifting is a primary occurrence such as in barns, feedlots, and loader applications.

Producers who operate power take-off (PTO) implements like a rotary cutter or baler will appreciate the additional working speeds with the 24F/12R PowrReverser transmission. High and low buttons are used to make fine adjustments in speed without needing to use the clutch, delivering improved productivity. 

The PowrReverser transmission provides 12 forward and 12 reverse speeds. Six well-spaced ground speeds place the operator in the important haying or rotary cutter range of 8 km/h to 20.9 km/h (5 mph to 13 mph). With this transmission, the operator can reach a top speed of 31.5 km/h (19.6 mph). The optional 24F/12R PowrReverser transmission delivers 11 well-spaced ground speeds to match the correct speed for a haying or rotary cutter application with a top speed of 40 km/h (25 mph). 

A dash-mounted PowrReverser modulation kit (LVB25727) is available to set the aggressiveness of the forward and reverse shuttle modulation that best fits the application or the operator's comfort level.

Operator controls

Two levers, one for speed and one for range, with the addition of an electrohydraulic left-hand reverser, provide operators optimum control and maneuverability. 

1. Range lever (right-hand side [cab], left-hand side [OOS]) selects four ranges (A, B, C, D).
2. Gear selection (right-hand side) selects speeds (1, 2, or 3) in the forward or reverse
3. Electrohydraulic left-hand reverser allows for quick and convenient shuttle shifting between forward and reverse at any
4. High and low buttons are located on the gear shifter for the 24F/12R PowrReverser
5. 12F/12R creeper transmission speed control (left-hand side)

Benefits

Forward and reverse speeds

All speed gears (1, 2, 3) are fully synchronized for shifting-on-the-go capabilities, putting less wear on the operator and saving time in the field. In the 12F/12R PowrReverser transmission, gears are synchronized for low shifting effort while the operator is doing field or loader work and during transport.

The PowrReverser transmission lineup also consists of a 12F/12R transmission with creeper. The creeper transmission functionality provides an ultra-low speed to match ground speed during tasks such as harvesting high-value crops, particularly vegetables, that are hand harvested.

The high and low speeds on the 24F/12R PowrReverser transmission can be shifted without clutching while the tractor is under load. This makes for quick speed changes when operating a rotary cutter or baler.

To further enhance awareness of reverse tractor motion, a backup alarm can be field installed (BSJ10026).

The ranges (A, B) are not synchronized. This means the tractor must be stopped for the operator to select the range. However, with operator input, the speeds have been well spaced out to minimize the need to change ranges within applications. The ranges (B to C, C to D, and D to C) are synchronized. That allows the operator to shift ranges on the go in transport and high-speed applications like operating a mower-conditioner.

Wet clutch

John Deere has led the industry in the innovation of wet clutches. In this wet-clutch design, five 17-cm (6.7-in.) diameter clutch disks provide optimum clutch modulation for smooth operation; the disks are oil-cooled for a lifetime of service.

The biggest advantage of a wet clutch is its ease of use as the required force to depress the pedal is minimal. Also, with a wet clutch, the need for frequent adjustment and clutch mechanism changeover is eliminated.
