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:
To disconnect the loader, the bucket has to be flat on a stable ground (1). The operator has to 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 have to 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 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.
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.
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.
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.
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.
