Hydraulic shut-off valve (open position)

Hydraulic shut-off valve (closed position)

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.

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.

All of these options are powered using a common electrical harness. Features can be added or subtracted to get the job done right.

Single-point hydraulic connection (open)

Single-point hydraulic connection (closed)

The 620R, 640R, 660R, and 680R 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.

Oil lines routed through the boom arm

Oil lines routed through the torque tube

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.

False rod cylinder

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.

Automatic mast latch system

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.

The high-volume bucket is intended for use with lighter-density high-volume materials. The bucket capacity makes this an effective tool for handling snow, wood shavings, and other loose materials.

Materials bucket

Materials buckets may be used for loading dirt, gravel, feed, and light materials as well as scraping, digging, and other general-purpose task

NOTE: Materials buckets are not compatible with replaceable cutting edges or digging teeth.

Replaceable wear edge

For those who frequently scrape on concrete, a replaceable cutting edge will greatly extend the life of the bucket:

• 1850-mm (73-in.) width replaceable cutting edge
• 2150-mm (85-in.) width replaceable cutting edge
• 2450-mm (96-in.) width replaceable cutting edge
• 2750-mm (108-in.) width replaceable cutting edge

Five-tine round bale/silage grapple with grille

All of the H-Series Loaders use the same five-tine pin-on grapple. The advantages of this grapple are:

• The pin-on method puts the least amount of stress possible on the bucket.
• The grapple has a wide stance, making it more difficult to twist.

High-performance operators will choose the five-tine grapple for its increased durability and load-carrying capacity. Advantages include:

• The ability to handle two large round bales instead of one (where loader capacity allows).
• Strong grapple arms allow the bucket capacity to be increased by almost twice the amount of normal bucket capacity in materials such as silage.

The grapple is equipped with twin cylinders to provide excellent clamping force. 

NOTE: The center tine of the five-tine grapple is slightly off center to avoid contact with the placement of optional digging teeth.

NOTE: The grapple is not compatible with materials or high-volume buckets.

Mid-mounted quick-couplers offer growers an economical approach to powering loader hydraulics. Hoses run from the tractor mid valve to the mounting frame where there are individually connected to the loader hydraulic hoses.

Single-point hydraulic connection

The R-Series Loaders feature 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.

R-Series mounting frame

6R Tractor with R-Series mounting frames

Mounting frames are designed to evenly distribute forces during loader operation. Hardware is accessible to torque to the correct specifications. The redesigned mounting frames ensure the automatic mast latch system can slide onto the frames to allow for mechanical connection between the loader and tractor.

Digging teeth can be added to the heavy-duty bucket for easier digging in hard ground or for breaking loose hard-packed materials such as manure or silage. Digging teeth are not compatible with replaceable cutting edges.

If swapping implements quickly is required, look to the hydraulic remote implement latch. Switching from a bucket to a bale spear can now be accomplished quickly, with limited movements of the loader, and without leaving the operator’s seat.

The hydraulic remote implement latch is powered by a hydraulic accumulator, which collects and stores excess oil generated through the normal operation of the boom (curl, dump, lift, lower). To activate the device, the two switches installed in the right-hand side of the operator’s station are pressed simultaneously by the operator. This action releases the oil, and unlocks the implement.

This feature does not require a third-function hydraulic system.
