The Loader user interface has been optimized by consolidating three separate loader applications into a single, integrated Loader app. All loader features (when ordered) are now accessed from one location, giving operators faster, more direct access while reducing screen navigation, clicks, and setup time.
Loader User Interface
It takes four steps to disconnect the loader: lower the loader, open the parking stand, remove the hydraulics, and unlock the mast pin.
Loader placed on the ground with the bucket leveled (1)
Open the parking stands (2)
Unlock the hydraulic (3)
Unlock the loader mast (4)
To disconnect the loader, the bucket has to be flat on a stable ground (1). The operator has to leave the cab and lower the self-adjustable parking stands on both sides of the loader (2): the self-adjustable parking stands allow the driver to park the loader on irregular terrain and still keep a good position relative to the mounting frame, to attach the loader correctly later on .The parking stands can be set without tools.
After lowering the parking stands, the hydraulic couplers on the right-hand side of the loader have to be removed (3) and the loader must be unlocked from the tractor mounting frames (4). After these four steps, the operator is ready to move the tractor (5 and 6).
Leave the loader boom (5)
Loader and tractor are disconnected (6)
Store the parking stands (1)
Connect the hydraulics (2)
Connecting the loader is fast and convenient thanks to the ramp design on the mounting frames and the automatic mast latch equipped with a floating device. Only drive the tractor to bring the mounting frames inside the mast until the latching indicators are in lock position. Then the driver can lift up the parking stands (1) and connect the couplers (2) for hydraulic and electric loader power to the tractor. Fast, intuitive and maintenance free design, the loader connection and disconnection brings the tractor ready for any tasks.
Daily work: Connecting different implements
Changing the implements is a daily task for many front loader operators. Thanks to the patented automatic implement latch (AIL) the connection of various buckets, forks, or other implements can be done in less than 3 seconds. The dedicated treatment and material choice ensure the rod supports the heaviest applications, which provides a durable and lifetime solution. The AIL is a base feature of the Euro carrier, which is compatible with all Euro implements. It is also available with the Combi Euro MX carrier.
Open the carrier handle (1)
Remove the implement (2)
To unlock the implement, the operator has to open the handle manually (1). Optionally, this is possible to do from the cab with the hydraulic implement unlatching (HIU). It requires minimal effort to unlock the implement, without the need of tools. The convenient position of the handle allows easy access for the operator. The operator needs to pull the handle and turn it clockwise. The handle will stay in the required position.
The next step is to remove the implement from the carrier (2): tilt the implement and lower the loader until the bucket touches the ground. The carrier rod is released from the implement hooks. The carrier handle moves to a standby position allowing fast latching later on.
Connect bucket with the carrier completely dumped
Implement locking positions (1, 2) and the trigger of the AIL (2)
The Automatic Implement Latch (AIL) locks the implement as soon as the implement lug touches the trigger plate on the carrier (2). To achieve this, the top bar of the carrier has to be connected to the implement’s top hooks and after start rolling back the carrier. But there is no need to completely roll back the attachment. The implement is latched on both sides of the carrier (1, 2). The fast and easy locking performs regardless of loader height.

John Deere R-Series Loaders are available with Mechanical self-leveling system (MSL)
Due to the design and the loader kinematic, the R-Series Loaders feature outstanding power in regards to lift capacity and lift height. The power of the John Deere tractor is transferred to the loader via the hydraulic system.
The underslung levelling link of the mechanical self-loader (MSL) loader is connected to the false rod cylinders which results in fast cycle times (dumping and rolling back). The geometry allows a more rollback capacity which the operator can experience with stronger breakout forces. The compact boom design features lower pivot points, allowing easy and convenient access for greasing.
The detailed specification of the loaders can give an overview of the lift height and lift capacity of each loader (665R,685R).
John Deere R-Series Loaders are built with a high level of durability
Durability supported by torque tube
The R-Series Loaders show a great level of durability due to the high-quality material. The modular cast-iron components on the loader are the foundation of a durable machine. The cast-iron mounting frames ensure a strong base for heavy-duty applications and guarantee a good connection to the tractor frame. This results in tested, reliable longevity.
The position and shape of the torque tube supports the heaviest loader applications and guarantees a stable behavior of the tractor and loader combination. Additionally, the compact boom design and the loader kinematics result in a strong and reliable solution the customer can experience in the field.
Front loader on the test bench
Cast-steel parts on the loader
To ensure a high quality with outstanding durability, the R-Series Loaders have been tested on a dedicated front loader test bench, where the loader is subjected to heavy duty farming operations. All pivot points are designed with a wider contact surface and are made from cast-steel material. The pivot pins has a dedicated diameter and undergo a specific treatment to ensure an outstanding durability.
The welded, directional bushings have a specific shape to provide ideal stress distribution and support the heavy-duty applications.
Major pivot points are equipped with replaceable bushings for low frequency of greasing, because the grease continuously is delivered during the loader work. New bushings can be installed thanks to the specific bushing design.
Position of pivot points on the loader
False rod cylinder
Fast bucket cycle times are important to dump the load from the bucket to be as productive as possible, while completing loading operations. The bucket cylinder design can have a major impact on the cycle time, especially for the mechanical self-levelling (MSL) loaders.
All MSL R-Series Loaders utilize false rod bucket cylinders. A false rod cylinder has a smaller displacement of oil requirement on the head end of the cylinder, which allows the cylinder to retract much faster than a normal cylinder.
Shut-off valve open
Shut-off valve closed
A hydraulic shut-off valve is included in base with the R-Series Ag Loaders to ensure the loader does not lower suddenly. This allows the boom to be locked if someone is required to be located under the loader boom, for example, during service work on the tractor.
Specs apply to MSL levelling for 6175R/6195R with front tyres 600/70R28 and rear tyres 650/85R38; actual specs may vary
