Single Point Hydraulic Connector on 5E

Single Point Hydraulic Connector on 5E

The 520M, 540M, and H310 Loaders can be configured 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.

Quick-Coupler connection is also an option.

Parking stands

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.

Refer to the operator manual for complete step-by-step procedure and specific information.

An abbreviated example is listed below with some images.

To remove the loader

• Raise loader enough to allow for parking stands to be lowered and not contact ground
• Place tractor in park, exit tractor and lower parking stands and lock into position
• Tilt bucket approximately 30 degrees and apply down pressure – this down pressure allows for the parking pins to be removed / installed
• With tractor in park, exit tractor and move parking pins from locked position into open position
• Using loader joystick, adjust hydraulics to allow for loader to rest on parking stands and bucket
• Loader should remain stable on parking stands and bucket while pivoting out of the loader mounting frames
• Once loader is freely positioned, turn tractor off, rotate joystick to release pressure from connection system
• Disconnect loader hydraulic hoses from tractor

Loader raised to allow for parking stands to be lowered and locked into place for parking

Lowering Parking Stands:  Parking stand pin is used to secure stand in up position during loader usage as well as lower position when being removed (parked).

With bucket tilted apply slight down pressure to the loader boom. 

Place the locking pin into the open position for loader to allow for the loader to be removed (parking pins are designed to stay on the loader; no need to be removed completely

Hydraulic shut-off valve (open position)

Hydraulic shut-off valve (closed position)

A hydraulic shut-off valve is included with the M- and 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.

LSS on 5E and 5M

Operator on/off switch on 6 Series tractors

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 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 5 Series Tractors, the accumulator is mounted near the inside of the rear right wheel.
