540R

The 540R Loaders comes base equipped with single-point hydraulic connector. This feature saves time and effort when installing and removing the loader.

To disconnect the hydraulic connection between the loader and the tractor, it is necessary to relieve the hydraulic system oil pressure on the tractor.

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.

Only leave the operator's station once to disconnect the loader

John Deere loaders are easily removed and reinstalled on tractors without tools. The automatic mast latch (AML) parking system allows removing or attaching the loader to the tractor in minutes without the need for tools.

Easy and quick steps to disconnect the loader:

1. Lower the loader to ground, turn tractor off and release hydraulic pressure from joystick
2. Exit operator's station
3. Open / lower parking stands (both left and right)
4. Turn the boom cylinder valve lever to the unlocked position
5. Remove loader hydraulics
6. Unlock the mast pins (both left and right) and then able to back away

Removing or parking the loader

To disconnect the loader, the bucket has to be flat on a stable ground (1). The operator must place the bucket flat on the ground, turn off tractor and release hydraulic pressure from joystick. (2) Exit the operator station and (3) lower the self-adjustable parking stands on both sides of the loader. 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. (4) After lowering the parking stands, the hydraulic couplers on the right-hand side of the loader must be removed and (5) the loader must be unlocked from the tractor mounting frames (both right and left side).

After these easy steps, the operator is ready to move the tractor.

Connecting the loader

Connecting the loader is fast and convenient thanks to the ramp design on the mounting frames and the AML 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 (visible from operator's station). Then the driver can lift up the parking stands, connect the hydraulic coupler 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.

A hydraulic shut-off valve is included with the R-Series 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.

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 mechanical self-leveling (MSL) loaders.

All MSL H-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.

An enhancement to the loader is the suspension system. A great level of loader productivity is achieved with the LSS.

• An accumulator charged with nitrogen and connected to the head-end lift cylinder hose through a T-fitting provides shock absorption
• The cylinders move in and out to allow the boom to float

Performance

• Bales can be transported more efficiently from one end of the field to the other over frozen, hard-packed, or rutted terrain

NOTE: Check bale handling capability of tractor before use.

• Pallets can be moved easily without sustaining cargo damage
• Pallets of seed or fertilizer can be carried across a yard without a bag spilling and creating a costly mess
• Properly ballasted tractor with LSS has increased stability, creating a smoother ride for the operator

Cost of Ownership

• Extended life of loader pins and bushings
• Less stress on tractor axle

Reasons for turning LSS off include:

• Digging applications - with LSS on, the cylinders retract slightly, losing lifting power
• Holding a grade when blading - with LSS on, it is difficult to hold a constant grade
• Precise pallet and bale handling - with LSS on, the load moves up and down slightly while being positioned
• Parking a loader - with LSS on, when down pressure is applied, the lift cylinders retract slightly, making it more difficult to park

The switch is conveniently located in the operator’s station to avoid having to exit the operator station to manually move the handle on the LSS.

LSS can also be ordered with a manual shutoff. Depending on the tractor/loader model, the accumulator is located in different places. On the H180 the accumulator is mounted outside the bottom of the mounting frame. On the 5 Series Tractors, the accumulator is mounted near the inside of the rear right wheel. On 6 Series Tractors and larger, it is mounted in between the hydraulic connection and the mounting frame.
