The H480 Loader features a single-point hydraulic connection that also incorporates the connection point for any electrical needs and the ability to relieve hydraulic pressure. In order to disconnect the hydraulic connection between the loader and the tractor, it has always been necessary to relieve the hydraulic system oil pressure. This has sometimes been difficult to accomplish and is also the reason why a coupling system was not offered on some tractors.

Now the ability to relieve the hydraulic oil system pressure is included with the single-point hydraulic connection, which allows for easily disconnecting both hydraulic and electrical lines to the loader from a convenient location with virtually no oil loss.

Over 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.

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

 

In order to remove or park the loader, apply slight down pressure to the loader boom with the bucket dumped at approximately a 30-degree angle. With the tractor in park, install the parking stands and place the mast pins in the open position.

Utilizing the boom circuit with the tractor in neutral, rotate the mast forward until the mast has rotated past the pin location on the mounting frame by extending the lift cylinder. Now using the bucket circuit, rollback the bucket until the mast is removed from the pocket and will clear the tires.

With the tractor in park, shut the engine off and relieve the hydraulic pressure as indicated for the tractor. Relieve pressure on the single-point hydraulic connection, then disconnect or open the single-point hydraulic connector.

A hydraulic shut-off valve is included with the H-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.

Fast bucket cycle times are important to dump the load from the bucket as quickly as possible, 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.

 

Therefore, all MSL M- and 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.

The electric remote carrier latching system provides enhanced productivity and improved operator comfort when changing loader attachments. This time-saving feature allows an operator to unlatch and latch attachments for Global or Global Category 2 Carriers without leaving the operator's station.

Unlike competitive remote latching systems, the John Deere electric remote carrier latching system utilizes a simple electric actuator instead of third function hydraulics and/or diverter valves for the loader.

A feature intended to improve loader productivity, the LSS allows the boom cylinders to float,
reducing the jarring effects loads are prone to over rough terrain.

  • 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
  • Bales can be transported more efficiently from one end of the field to the other over frozen, hard-packed, or rutted terrain
  • 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
  • Extended life of loader pins and bushings
  • Less stress on the tractor axle
  • Properly ballasted tractor with LSS has increased stability, creating a smoother ride for the operator

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 loader suspension system is controlled by a switch conveniently located in the operator station so it can be easily reached for activation or deactivation as needed.
