All-new R-Series Front Loaders (Revised 4-Feb-2015)  

Following the initial introduction of the mechanical self-leveling (MSL) 640R Three-Function Loader, the 620R, 640R (all configurations), 660R, and the 680R are now available. The loaders have been designed with the Final Tier 4 (FT4) 6 Family Tractors in mind.

The R-Series Loaders build upon the H-Series, bringing improved specifications, better tractor integration, and new features.

Due to the tiered approach of the tractor introductions, there are several things to keep in mind with the R-Series Loaders:

  • The large-frame 6R Tractors (175-215 hp) have been in production with H-Series mounting components and will continue to be until model year 2016 (December 2015), meaning they should be ordered with the bridge solution H360 or H380 Loaders. Beginning December 2015, the tractors will be produced with R-Series components so they will require either 660R or 680R Loaders. A separate product announcement will be released as this date approaches.
  • Large-frame 6M Tractors (175-195 hp) will begin production with R-Series components so they will require either 660R or 680R Loaders.
  • Small-frame and mid-frame 6R and 6M Tractors (110-155 hp) will begin production with R-Series components so the R-Series Loaders must be ordered for them, either 620R, 640R, or 660R Loaders.
For full information on the differences between the loaders and compatibility, please refer to the Sales Manual. An abbreviated compatibility chart is also available at the end of this announcement. The H-Series Loaders will remain available for order until November 2015 for use on Interim Tier 4 (IT4) or earlier machines.
 
 
New features
 
Automatic mast latch system

Automatic mast latch (AML) system - the AML system keeps trips on and off the tractor to attach and remove the loader limited to once per operation.

To park the loader, simply rest the bucket flat on the ground, relieve the hydraulic pressure, exit the tractor to fold down parking stands, disengage the latch system on both sides, disconnect hydraulics, and open one valve located on the right-hand boom cylinder of the loader. Simply back away from the loader and the process is all done.

To reattach the loader, drive the tractor into the loader; it mechanically connects the masts to the mounting frames, in turn removing pressure from the parking stands. Exit the tractor once to fold the parking stands, close the valve located on the right-hand boom cylinder, and attach the hydraulics.

 
Global carrier
Implement automatic latch - with the H-Series Loaders, the global carrier had to be rolled fully back in order to engage the latch-trip mechanism and secure the loader attachment (bucket, pallet fork) to the carrier. The R-Series global carrier features our new implement automatic latch, meaning the carrier will only have to rest flat to the attachment in order to lock.

Remote implement latch - updated hydraulic remote implement latch will improve reliability and durability of the electric remote latch found on H-Series Loaders. The system will not require the use of third function hydraulics; instead it will use an accumulator system that relies on dumping and curling the implement to charge the system with fluid. One dump or curl cycle will allow the carrier to be unlatched and latched multiple times.
 
Side-slung leveling links
Side-slung leveling links - in an effort to improve operator visibility, the leveling links have been relocated from the top of the boom to the sides of the boom. This will allow the loader to maintain its ability to level itself through the full range of motion, while opening up the visibility forward and to the sides of the loader.

Third function hydraulics - to provide an easily accessible location for the third function hydraulic connection for grapples, the connection point has been moved to the loader carrier.

Name and numbering - to try and better help understand the name and numbering as well as better match the system used by tractors, changes have been made to the name and numbering strategy. For example, the 640R Loader:

6: loader primarily fits on a 6 Family Tractor
4: third largest loader (starting at 0 and moving up evenly)
0: placeholder in case further designation is needed in the future
R: designates that the loader is premium
