The 520M, H240, 540M, H260, 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.

Loader removal (parking) made easy
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.
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, lower the parking stands and place the mast pins in the open position.

Rotating mast pin to 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. Using the bucket circuit, roll back 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 (rotating the joystick). Disconnect or open the single-point hydraulic connector (or remove couplers if no single point is installed).

Boom lockout for easy service

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.

False rod bucket cylinders improve productivity

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 mechanical self-leveling (MSL) loaders.
Therefore, all MSL 520M 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.

Loader suspension system (LSS) to enhance the ride

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 
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 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.
