The engine uses the latest technologies to optimize fuel economy, improve control and accuracy, and reduce environmental impact. The common rail system (CRS) optimizes fuel economy and reduces operating costs comparted to engines not using CRS technology. High-pressure injection atomizes fuel into finer particles which burn more completely. It results in improved fuel economy and a lower cost of operation.

 

The electronic control unit (ECU) provides optimum fuel control and accuracy. ECU monitors and controls the engine. It continuously monitors engine conditions and adjusts the fuel delivery accordingly to ensure optimum performance and emissions.

 

The engine comes with an after-treatment system. The system operates automatically. The exhaust filter consists of a diesel particulate filter (DPF) which captures particulate matter (PM) contained in the exhaust gas. Using a natural cleaning process, most of the PM trapped in the exhaust filter is eliminated by the heat of the exhaust stream generated by normal use. In situations of low temperature, engine speed, or load factor, an active cleaning cycle is initiated. In this cleaning cycle, the exhaust gas temperature is raised by injecting additional fuel during the exhaust stroke of normal vehicle operation to the diesel oxidation catalyst (DOC).

 

After many hours of use, the exhaust filter may require an ash removal service.

DPF cleaning

Depending on the load that the tractor is under, as well as ambient temperature, humidity, and engine speed, the DPF may build up with particulate matter, thus requiring cleaning. Filter cleaning is determined by one of three factors:

• A prescribed time-based estimation of needed filter cleaning
• DOC/DPF pressure sensors
• A particulate matter buildup estimation based on load conditions

 

Once one of the three conditions has been met, filter cleaning will occur.

 

There are three different types of filter cleaning processes:

• Passive filter cleaning
• Active filter cleaning
• Parked filter cleaning

Passive filter cleaning

Passive filter cleaning occurs naturally when the engine is generating enough heat to oxidize particulate matter. This automatic process occurs continuously during normal operating conditions. No tractor icons or symbols appear on the display during passive filter cleaning.

 

NOTE:  Passive filter cleaning requires no operator involvement, and there is no interruption to tractor operation.

Active filter cleaning

If conditions (temperature, load, or speed) for passive filter cleaning cannot be achieved, then PM is removed using active filter cleaner.

 

To achieve the required conditions, exhaust temperature management (ETM) manages the initiation and duration of active filter cleaning. ETM can adjust numerous engine parameters and/or inject a small quantity of fuel into the exhaust stream for a short duration. The fuel turns to vapor and chemically reacts with the catalysts in the DOC to create heat to oxidize the PM.

 

It is important to note that at no time is the fuel in the DOC/DPF ignited, and there is no flame within the DOC/DPF.

 

Like passive filter cleaning, active filter cleaning requires no operator involvement, and there is no interruption to tractor operation.

Parked filter cleaning

In some instances where passive and active filter cleaning have not fully cleaned the PM from the system, a parked filter cleaning may need to take place. In general, the only time a parked filter cleaning will need to occur is when automatic filter cleaning has been disabled for an extended period of time and multiple warnings to engage filter cleaning were ignored or if the tractor has been used during light load conditions. Additionally, when the automatic filter cleaning process has been deliberately interrupted multiple times, or if active filter cleaning has failed numerous times due to a failed component, a parked filter cleaning may be requested. In these rare instances the operator will have to park the tractor and start the filter cleaning process.

 

The parked filter cleaning process needs to be activated based on usage and operation of the tractor. The process will take approximately 30 minutes.  See the operator’s manual for more details.

 

This system constantly monitors the soot level of the tractor; making sure the tractor is always in peak performance condition.  This ensures high performance at all times.

 

NOTE: Number of hours since last regeneration and soot level percentage are viewable on LCD display.

The 3E Tractors are available with a two-range hydrostatic transmission (HST) incorporated in a die-cast aluminum transmission case. Fluid under pressure transmits engine power to the drive wheels via a closed-loop pump and motor arrangement. Infinite ground speeds allow the operator to match the speed of the tractor to the job.

• No clutching for fast and easy direction changes
• Twin Touch™ foot pedals for quick and easy forward/reverse operation
• Transmission oil cooler cools transmission oil for longer transmission life

Safety features of the HST include:

• The tractor will only start with the range lever in neutral
• The engine will shut off if the operator leaves the seat unless the range lever is in neutral
• The engine will shut off if the operator leaves the seat and the power take-off (PTO) is engaged

Twin Touch foot controls

Key John Deere advantage – John Deere’s Twin Touch foot controls offer several key advantages over competitive HST models tractors.

• Some competitive hydrostatic tractors use a treadle pedal (toe-heel) design foot control for operation of the HST
  • Requires the operator to use both toe and heel to change direction, resulting in increased operator fatigue
  • The Twin Touch configuration also makes it easier to “inch” the tractor forward or rearward (i.e., when attaching to implements)

Optional cruise control

The 3E Series Tractors can be outfitted with an optional cruise control switch that is installed on the right-hand control console. This gives operators the ability to keep a constant speed when in transportation, field mowing, or other applications where extended use of the transmission is needed. This kit is very quick and easy to install for those who desire this feature.

Integrated hydrostatic pump and motor

• Sauer-Danfoss® company provides the integrated pump and motor; this assures that the components are matched to each other, providing maximum efficiency
• Reduces powertrain shock loads
• Provides strength and durability needed for operating such attachments as loaders
• One reservoir (with one check point and fill point) for the transmission, differential, and hydraulic system speeds up daily maintenance
• Mechanically actuated by Twin Touch foot pedals allow selecting both directions of travel and speed with the touch of a toe

Transmission reservoir fluid checkpoint

• Easy-to-reach transmission fluid dipstick allows for frequent checks of the transmission fluid level.

Transmission fill point

• Easy-to-reach transmission fill point (A) is located on top of rear axles on the right-hand side.

Integrated brake and differential lock pedal

• Foot-actuated differential lock is integrated into the brake pedal to simplify operator controls; the differential lock is included as base equipment to assist traction in tough spots.
• Press the brake pedal down half way to engage the differential lock that locks the rear axle for improved traction in tough spots.

Two-post Roll-Gard ROPS

3E Series Tractors are equipped with Roll-Gard ROPS. These folding ROPS meet the ASABE standards for compact utility tractors.

• With the Roll-Gard ROPS folded down, producers can easily to get their tractor into a garage with a standard 2.1-m (7-ft) garage  door.

 

NOTE: The use of seat belts is recommended at all times when operating the 3E Series Tractor with the folding ROPS upright.

 

An optional canopy (LVB25334) is available to help protect the operator from the elements.

3E Series Tractors can be equipped with a field-installed rear hydraulic remote kit, providing two additional hydraulic spools on the back of the tractor. This kit can be field installed on a tractor with a loader or without a loader.

 

 NOTE: Not compatible with the power beyond kit.

 

The functions are completely separate from the loader. These rear remotes can be hooked up to a wide variety of implements and attachments such as follows:

• Hydraulically angled blade
• Hydraulically controlled chute/spout on a 3-point hitch-mounted snow blower
• Hydraulic scarifiers on a box blade
• Many other hydraulic rear attachments

This versatile kit gives 3E Series Tractor operators the options they desire for putting their tractors into a wide range of tasks.

 

The first spool is equipped with a float position, giving the operator the ability to contour the landscape and improve the final grade with certain implements.

 

NOTE: Neither of the spools in this kit are equipped with a detent position; therefore, they should not be hooked up to anything with a motor, as the valve was not designed to be run open. The kit is designed for momentary, on-demand hydraulic flow such as moving a cylinder.

One of the greatest operator concerns involves difficulty in attaching tractor implements. John Deere has addressed this issue with the iMatch Quick-Hitch.

The iMatch Quick-Hitch provides easy hookup and a guaranteed fit for all Category 1 implements that are designed to meet the American Society of Agricultural and Biological Engineers (ASABE) Category 1 Standard S278.6 for quick-attach hitches.

• All implements require a set of bushings in order for the attachment to fit and work properly with the iMatch Quick-Hitch. One set of bushings comes with the iMatch Quick-Hitch.

NOTE: The bushing set can be seen in the picture above. These bushings allow the hooks on the iMatch and the pins on the implement to fit together properly. All other implements (box blades, tillers, rear blades, etc.) will require a set of bushings to enlarge the pin to fit with the iMatch hooks. Bushings of different lengths can be found in the parts system or through a bushing supplier (see dimensions below).

• Upper bushing
  • Inside diameter: 1.93-1.95 cm (0.76-0.77 in.)
  • Outside diameter: 3.15-3.18 cm (1.24-1.25 in.)
• Lower bushings
  • Inside diameter: 2.24-2.26 cm (0.88 to 0.89 in.)
  • Outside diameter: 3.63-3.66 cm (1.43 to 1.44 in.)

Regular service and maintenance are essential to the performance, productivity, and longevity of the tractor.

• Easy access to most regular service points minimizes service time.
• Four quarter turn fasteners allow operators to easily remove the engine side panels without tools to access the engine compartment.

• Tractors are equipped with extensive onboard self-diagnostic capabilities and are fully compatible with the John Deere exclusive Service ADVISOR™ system.
• Hydraulic oil service interval increased to 1200 hours when using Hy-Gard™ products.
• Hydraulic oil filter will need to be changed every 400 hours.
• Fuel tank is located on the rear of the tractor to allow for easy access when fueling.

• Gas-lift hood support eliminates the need for a mechanical prop rod.

• Daily service requirements are minimal and simple to accomplish. Most service interval requirements can be performed with a basic understanding of procedures and common tools.

All items in the daily service schedule can be performed without the use of tools:

• Engine oil, hydraulic oil, coolant level, and the water separator can be conveniently accessed.
• The engine can be easily accessed by simply raising the hood for more periodic maintenance checks.

NOTE: Always refer to the operator’s manual for complete maintenance and service recommendations.
