You can opt for the 12F/4R Top Shaft Synchronized (TSS), 12F/12R PowrReverser™, 24F/8R TSS Hi-Lo, 24F/12R PowrReverser Plus on the 6115D Tractor. It's an economical option that's ideal for applications that don't require a lot of repeated forward/reverse shifting — mowing and baling, for example.
Gear selection lever
Electrohydraulic left-hand reverser
For operators requiring more field speeds to achieve the most precise operating ranges, four transmission options are now available in the 6D Series.
The 24F/8R TSS Hi-Lo and 24F/12R PowrReverser Plus transmissions offer 24 forward speeds for ultimate in speed selection. Convenient push-button controls actuate the electrohydraulic high/low selector.
The forward lever selects one of three 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 range 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.
Hi/Lo selector on gear lever
The Hi/Lo 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 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.
Those selecting the 6D Series PowrReverser transmission are looking for 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.
The 12F/4R TSS and 12F/12R PowrReverser transmissions offer five well-spaced ground speeds placing the operator in the important field-working range of 4 km/h to 12 km/h (2.5 mph to 7.5 mph). The 24F/8R Hi-Lo and 24F/12R PowrReverser Plus transmission will deliver 10 well-spaced ground speeds to match the correct speed for each application. And, with a top speed of 31.6 km/h (17.6 mph), operators will be able to move fast from application to application—getting more done in less time.
24F/12R PowrReverser Plus transmission includes:
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.

Hi/Lo and PowrReverser Plus high/low buttons
Two levers, one for speed and one for range, with the addition of an electrohydraulic left-hand reverser in PowrReverser transmissions, provide operators optimum control and maneuverability.
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 them time in the field. In all 6D transmissions, gears are synchronized for low shifting effort while the operator is doing field or loader work and during transport.
The high and low speeds on the 24F/8R Hi-Lo and the 24F/12R PowrReverser Plus transmissions can be shifted without clutching while the tractor is under load. This makes for quick speed changes when operating in uneven conditions.
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.
Transmission options:
12F/4R TSS wet-clutch transmission
12F/12R PowrReverser wet-clutch transmission
24F/8R Hi-Lo wet-clutch transmission
24F/12R PowrReverser Plus wet-clutch transmission

PowerTech E
6D Series open-center hydraulics
All 6D Series Tractors feature a gear-driven, open-center (constant-flow) hydraulic system with a maximum pressure of 2830 psi (19,500 kPa).
The tractor incorporates a triple hydraulic pump design. The implement, steering-transmission lubrication systems, and transmission all function separately; all three systems utilize a common reservoir resulting in ease of serviceability. Two selective control valves (SCVs) are in base with a third deluxe valve as optional equipment.
Pressure available when needed
Pressure for entire system is established by function requiring the highest pressure. As demand lessens, so does pump pressure and engine power requirement. Steering section (additional 28.5 L/min [7.5 gpm] in base equipment) provides full power when needed for steering. Transmission section (additional 28.5 L/min [7.5 gpm] in base equipment) provides hydraulic pressure for the power reverser transmission.
The steering and transmission circuit functions return to sump, giving improved system performance and cooling. By returning functions to sump, the system is simplified and provides faster service and increased uptime.
Remote flow rating
| Models | Rated flow | @ engine rpm |
| 6100D, 6115D, 6130D |
72.3 L/min (19.1 gpm) | 2100 |
The steering side and transmission side of this pump provides an additional 7.5 gpm (28.5 L/min) respectively.
PTO yellow knob
540/1000 rpm PTO
The 6D Series Tractors feature an independent and now electric 540/1000 rpm PTO as base equipment. For feeding, mixing, baling hay, or any other PTO application, the 6D Series 540/1000 rpm PTO can match up efficiently to any requirement.
An easy-to-use push/pull knob on the right-hand console allows the operator to quickly and smoothly engage and disengage the PTO. If the tractor is stopped or is being downshifted, the PTO rpm levels can be maintained. To engage the PTO, simply pull up on the knob. When the PTO is engaged, a light on the instrument panel illuminates. To disengage the PTO, simply push the knob back down.
Adding to operator safety, the tractor does not start with the PTO lever engaged. An alarm sounds if the operator attempts to leave the seat with the PTO engaged.
NOTE: Operators should disengage PTO before the engine is stopped.
The 6D now offers a PTO wet clutch for a long, reliable lifetime of operation. The wet clutch eliminates the need for frequent adjustment and clutch mechanism changeover.
Operators can easily switch between 540 and 1000 rpm-driven implements simply by removing the stub shaft and reversing its position. The reversible 540/1000 PTO stub shaft is located in a dry cavity to allow changing from 540 to 1000 rpm or vice versa without any oil spillage. Just remove the snap ring to remove the shaft.
The hood tilts opens wide allowing unencumbered engine compartment access. An easy-reach tether cord allows access to effortlessly close the hood. Overriding the two gas struts permits the hooding up to 90 degrees. Unhooking the tether from the radiator support allows the operator to open the hood even further to provide better access for servicing the under hood components.
The tilt-up hood provides easy access from the ground to:
Fuel filters
6D Series (right-hand side view)
Vertical engine oil and fuel filters minimize spilling for cleaner and faster changes. 500-hour service intervals (when using John Deere Torq-Gard™ oil or Plus-50™ lubricant and filter) for engine oil and filter, fuel filter, and cab air filter reduce maintenance costs over the life of the tractor.
Two engine fuel filters provide the needed protection for the fuel system:
Radiator
Blowing out the radiator is easy and convenient with the 6D Series Tractors equipped with an in-base, tiltable radiator assembly. Open the hood to clean out the radiator, fan, and cooling package. The condenser can be tilted for better access.
6D Series coolant tank
The coolant recovery tank, located behind the air filter, is easily accessible from the ground.
Engine air filter
The engine air filter is located under the front of the hood above the radiator. Undoing the quick-attach fastener allows for fast and easy servicing - no tools required. The Power Core air filter removes more than 93 percent of foreign material before it reaches the filter element.
Cab air filter
The cab air quality system is comprised of two fresh air cab filters. A filter is located on the bottom side of the left and right side cab roof is easily accessible by removing two wing screws and removing a sealed cover plate.

Brake pedal adjustment (left shown)
Easy brake pedal travel adjustment is provided on cab and open operator station (OOS) tractors. Turnbuckle linkage is located at the top side of left and right rear axles.
6D Series cab tractor
A rollover protective structure (ROPS)-certified, factory-installed cab is available to all operators. The cab provides protection from heat and cold, wind, noise, and offers a climate-controlled environment. The cabs are also assembled to the tractor chassis as a complete unit mounted on composite isolators.
Cab interior
By including the floor and steering column as part of the cab, it significantly reduces noise levels in the cab. It also creates a more sealed environment by reducing airborne particles entering the cab, such as dust, pollen, and other contaminants. The 6D Series Cab Tractors are base equipped with a mechanical cloth seat for standard comfort. For those who will be operating on rough or unstable terrain, an optional air suspension seat is available that gives maximum comfort.
The cab is incredibly spacious, and the flat floor creates a spacious feel. The operator of a 6D Series Cab Tractor will appreciate the reduction in noise and vibration through the seat, steering wheel, and lever controls. By adding the cab to the tractor, the noise level is decreased.
The ceiling control panel is located to the upper right side and the air conditioning components are located on the upper rear corners of the cab, where visibility is not as critical. This provides the operator with visibility to the loader at height unmatched by any competitor. For excellent rear visibility, the fuel tank is located below the left-hand side of the platform.

6D Series Tractor
Decal
The tractor model numbers are comprised of four positions. The first number designates the family while the next three numbers represent the approximate engine horsepower. The fifth and sixth positions are represented by a letter. The first letter indicates the level of capability or price a tractor has. Not every tractor will have a second letter. But if it does, the second letter represents a special configuration of the tractor.
The size of the tractor is how large the tractor is compared to other tractors John Deere offers, using the similar sizes of today's product groupings and still sustaining the tradition of the name and numbering legacy. These are referred to as Six Series Tractors. This name and numbering system will not change that. The 6D is similar in size to the 6003 Series.
The second position is the tractor's approximate engine horsepower. The 6100D at 99 engine hp, and 6115D at 118 hp have been rounded to the nearest 5 hp. John Deere has promoted PTO horsepower for its utility and row-crop tractors and engine horsepower for its four-wheel drive (4WD) tractors. This has led to some confusion in the marketplace. Although promoting PTO horsepower has its benefits, using bare-engine horsepower allows for a more consistent means of promoting tractor horsepower in a global market.
Bare-engine horsepower is measured by running just the bare block engine with the front fan. With bare engine horsepower, John Deere is using the International Organization for Standardization (ISO) 97/68 E-C standard for determining the bare-engine horsepower at rated engine speed, given in metric horsepower, not Society of Automotive Engineers (SAE). This unit of measurement is used globally to describe off-road engines. This will allow John Deere to consistently promote the tractor's approximate horsepower within the model number across all tractors around the world.
The third position is the tractor's capability or price level within its family. In general terms, capability is the specification level of that tractor series, such as the type of engine, transmission, frame, and overall design; all leading to price. The letter D would equal a very basic tractor; M would signify a premium tractor, while the letter R would equal a very premium tractor with many options and features. The higher the letter is in the alphabet the higher the tractor's spec level. If the tractor has a second letter, the second letter represents the configuration of the tractor. For example, H will designate high-crop and V will designate a vineyard design.
Another important part of the name and number system is the way that these tractor models are pronounced. The former system would have said sixty-one-forty-D, but since the second, third, and fourth positions are the engine horsepower and not part of the tractor's size, the numbers need to be separated.
The correct way to say this tractor lineup is:
This is a significant change to what has been used in the past, but the value and the solutions of these tractors remain the same.
