Loader options to improve productivity
The R-Series Loaders come with a number of options to enhance an operator’s experience and to allow more productivity in the field. These options include lighting, hydraulic remote implement latch, loader suspension system, and industry-exclusive return-to-position (RTP) Gen2 technology with electronic self-leveling.
Loader lights for enhanced visibility in low-light conditions
Hydraulic remote implement latch
Return-to-Position (RTP) Gen2 with electronic self-leveling
Loader suspension system for a smoother ride
All of these options are powered using a common electrical harness. A customer can add or subtract the features required to get the job done right.
Boom lockout for easy service
A hydraulic shut-off valve is included with the R-Series Ag Loaders to ensure the loader does not lower suddenly. For example, this allows the boom to be locked out when someone is required to be located under the loader boom for service work on the tractor. It should not be used for extended periods of time unless an appropriate support stand is also utilized.
Concealed oil lines improve appearance and reduce damage
Through time, increased width in tractor hoods have caused issues with available space for running traditional oil lines of a loader along the boom, making them more susceptible to damage.
To improve this situation, the oil lines have been routed through the boom arm and the torque tube, improving line protection and the appearance of the loader.
Loader removal (parking) made easy
R-Series Loaders are now even easier to remove and reinstall due to an automatic mast latch system. Simply exit the tractor once for removal and once for reinstall to reduce the amount of downtime associated with loader parking.
For a more detailed look at the steps, please refer to the operator’s manual
To remove the loader, follow these simple steps:
- Set the bucket flat on ground, release the hydraulic pressure, and exit the tractor.
- Set the adjustable parking stands on the ground.
- Flip the lock handles located on either mast to unlock the loader from the frames.
- Disengage the hydraulic couplers and return to the tractor seat.
- Back away from the loader.
To reinstall the loader follow these simple steps:
- Drive the tractor into the loader, resulting in mechanical connection (no more maneuvering the loader to fit into the frames).
- Exit the tractor.
- Fold up the parking stands.
- Attach the hydraulic connection.
- Enter the tractor and have full control of the loader.
False rod bucket cylinders improve productivity mechanical self-leveling (MSL) only
Fast bucket cycle times are important to dump the load from the bucket as quickly as possible (quite often) in order to be as productive as possible while completing loading operations. The bucket cylinder design can have a major impact on this cycle time, especially for the 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 this cylinder to dump much faster than a normal cylinder.
Single-point hydraulic connection saves time
The 620R and 640R Loaders can be ordered with a single-point hydraulic connection that also incorporates the connection point for any electrical needs. To disconnect the hydraulic connection between the loader and the tractor, it is necessary to relieve the hydraulic system oil pressure on the tractor.
