John Deere 520M Loader

Boom lockout for easy service

Hydraulic shut-off valve (open position)

False rod bucket cylinders improve productivity

False rod cylinder

Loader suspension system (LSS) to enhance the ride

Nitrogen-charged accumulator and electric valve

• 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.
