6M Series: Expect More
Mowing, tedding, baling and feeding – the daily jobs of a livestock operation become quick work with these machines. Their short wheelbase also make them perfect for front loader work.
6MC – 6RC Series Cab Tractor
The 6MC and 6RC Series Cab Tractors provide room and great visibility, making row-crop and loader work easier while protecting the operator from environmental discomfort. These cab tractors combine form and function into an eye-pleasing combination with easy, uncluttered access to all tractors and implement controls.
The cab provides a comfortable working environment for those long days in all conditions with a low in-cab noise level. All-around visibility of 320 degrees from within the cab ensures accurate tractor placement, implement hookup, and optimum tractor performance.
Mechanical front-wheel drive (MFWD) front axle - Triple-Link Suspension (TLS)
TLS provides higher operator comfort by reducing fatigue and increases productivity.
It is optional and available for all 6RC Series Tractors with the following features:
- Self-leveling system with +/- 50-mm suspension travel under all axle load conditions.
- Permanent engagement of axle suspension with automatic adjustment of the sensitivity and suspension rate for the axle load (from a heavy rear-mounted implement to heavy front loader work)
- Optimized draft performance with its long draft member, by synchronizing with the hitch-sensing system to compensate power hop effect under heavy pull conditions.
- Up to seven percent more power to the ground
6MC and 6RC Tractors are based on one frame size and wheelbase:
|2400 mm (9.4 in.)|
Strong steel frame has been a John Deere industry exclusive since 1992:
- Unique solution achieves higher payloads without increasing tractor weight
- Bridge-type frame provides superior structural strength and allows compact modular construction of transmission units
- Full frame carries the load while the powertrain transmits engine power to the final drive
- All components have a dedicated function and are designed without compromise
- Larger implements and heavier loads can be accommodated, resulting in higher levels of productivity
- Operators have less downtime and more uptime with quicker turnaround for service
- Complete modular component replacement is allowed without splitting the tractor in half
- Frame mounting allows easier component servicing without disturbing other systems
- The cab tilts so the tractor does not have to be split to access key components
Common transmission features
John Deere transmissions combine power-saving technology with well-proven design features to ensure:
- High efficiency
- Low noise
- Convenient operation
- Low service costs
For the 6MC – 6RC Series Tractors, the following basic transmissions are available:
|PowrQuad™ Plus transmission||30 km/h (18.6 mph)||16/16||Not applicable|
|PowrQuad Plus||38 km/h (23.6 mph)||16/16||16/16|
|PowrQuad Plus||40 km/h (24.9 mph)||24/24||24/24|
|AutoQuad™ Plus transmission||40 km/h (24.9 mph)||Not applicable||24/24|
|AutoQuad Plus Eco||40 km/h (24.9 mph)||Not applicable||24/24|
The full frame is designed to withstand heavy load and twisting applications, which allows the transmission and engine to be modular designed instead of being an integral part of the frame.
Since the transmission is not used as a structural member, there is greater flexibility in manufacturing processes for integrating options such as a creeper or mechanical front-wheel drive (MFWD).
- Differential housing
- Range module
- Option module (creeper)
- PowrQuad module (or PowrReverser and PermaClutch™ 2 clutch)
- MFWD – clutch module
- Power take-off (PTO) module
Three large clutch disks provide optimum clutch modulation for smooth operation, and the disks are oil-cooled for a lifetime of service. The PermaClutch 2 is especially suited to tough tractor applications, such as continuous front loader operations or other applications involving a large number of shuttle shifts.
Helical cut gears
The helical cut gears provide large-tooth contact for greater torque-transmitting capability and quieter operation.
The pressurized lubrication system delivers cooled and filtered oil under all conditions. A warning light alerts the operator if oil pressure drops, preventing damage to the transmission.
All gear shift levers are conveniently located on the right-hand console. Easy-to-use shift pattern allows precise shifting without confusion.
Pressure compensated system (PC) – 65 L/min (17.2 gpm) and 80 L/min (21.1 gpm)
6MC Series Tractors feature a John Deere-designed, open-center, constant-flow pressure compensated (PC) hydraulic system with variable pressure up to full pressure of 200 bar (2900 psi).
Base equipment is a 65 L/min (17.2 gpm) gear pump for all 6MC models, optional a 80 L/min (21.1 gpm) gear pump for a higher flow is available.
Differences between PC and PFC system
There are two different hydraulic systems available (PFC and PC).
The PC system offers a gear–type pump and is based on a continuous oil flow. The flow is always maximum, regardless of the need of the tractor or the implement. The pressure can vary depending on the settings of pressure regulating valves, but the maximum flow is generated by the gear-type pump, which has a direct influence on the engine efficiency.
The pressure is variable because of using pressure regulating valves, which effect a loss of power because
the pump is always in action and has to be driven by the motor. So, the pressure is not very high, and a big volume of hydraulic oil always circulates in the system.
The PFC system has a consumption–based hydraulic pump, which is mostly a piston pump. When no
hydraulic consumers are needed, the pump works in a reduced stand-by flow. If the tractor or its implement needs more hydraulic power, the pump starts to increase flow or pressure. The oil flow and oil pressure depend on the demand, and thanks to that, the pump is always in the most efficient condition. This system has a positive influence on the whole efficiency of the tractor because the hydraulic power is only provided when it is needed.

- No hydraulic users
- Mid hydraulic demand
- Maximum hydraulic demand
Pressure- and flow-compensated system (PFC), 80 L/min (21.1 gpm) and 114 L/min (30.1 gpm)
6RC Series Tractors offer a closed-center, pressure-and-flow-compensated (PFC) hydraulic system with 80 L/min (21 gpm) of flow to the remotes up to 200 bar (2900 psi) of variable working pressure as base equipment. If a higher flow is required, a bigger pump with 114 L/min (30.1 gpm) is available.
The hydraulic system is load sensing, which means a valve on the pump immediately initiates pump flow when required. When flow is no longer required, the pump returns to low-pressure, no-flow standby mode.
Advantages of this system:
- Reduced load on engine
- Improved fuel efficiency
- Enhanced oil cooling
- Reduced internal leakage
- Reduced hydraulic noise levels
- Less strain on hoses and seals
Pressure for the entire system is established by the function requiring the highest pressure. As demand lessens, so does hydraulic pump pressure and engine power requirements.
Other hydraulic system advantages include:
- Mechanical-controlled valves
- Hydraulic steering for effortless operation
- Hydraulic wet-disc brakes that provide an excellent brake performance
- Three-point hitch with increased lift capacity that can handle even the heaviest implements
High-capacity hydraulic pump
The hydraulic pump is located close to the hitch valve and selective control valves, allowing:
- Fewer and shorter lines
- Quick system response times
- Minimized energy losses
Essential services have priority
The priority valve ensures, even at low idle engine speed, full power to the essential services like:
- Hydraulic trailer brakes, if equipped
Hydraulic and transmission systems are functionally separate; however, both systems utilize a common reservoir for easy serviceability.
Oil takeout capacity with/without additional tank
With PFC hydraulic system, an extra 12-L (3.2-gal.) oil reservoir is available to increase the oil withdrawal capacity of the hydraulic system. This permanently allows the optimum oil level of all drive components with advantages for durability and efficiency.
Intelligent Power Management (IPM) for transport and PTO applications
The Intelligent Power Management feature for 6RC Tractors is used for many typical farming operations that use the rear power take-off (PTO) in high-power applications, or when the tractor is used as a transport vehicle. Producers looking for more power in non-stationary PTO and transport applications will take full advantage of this feature.
In high PTO power applications or where heavy trailers, carts, or implements are moved to and from various locations, this feature provides significant additional capabilities:
- Improved productivity
- Quicker acceleration
- Better holding of desired transport speeds
