One outstanding boom designed with selected and tested components
Integrated hose design
Calculated and tested design
The H-Series Front Loaders are the best partner for John Deere tractors. The boom is specially designed to optimize visibility with a wide dimension and integrated hydraulic hoses. The durability of the loader, which uses tested components, ensures the tractor will operate at maximum efficiency when used with the front loader.
Visibility and durability are important for the operator, but so is control. To ensure control of the loader attachments, H-Series Loaders are equipped with an exclusive bucket-level indicator, which indicates the angle the attachment is situated.
Designed with a torque tube in a low position, the H-Series Loaders provide the operator good visibility of the attachment no matter what lift height the loader is placed. The low position of the torque tube also allows clearance for the tractor’s front lights, which provides an ideal lighting solution for nighttime use.

The integration of the hydraulic components also provides good operator visibility because everything is located inside the boom.
With the concealed oil lines, visibility is improved and the components are protected such as hoses, suspension, the diverter valve, and the relief valve. The ability to take the cover off the torque tube allows operators to access to the complete hydraulic package, which enables working on the hydraulic parts to be completed in a limited time.

|Relief and diverter valve
The H-Series Front Loader is a premium product with concealed hydraulic oil lines. The suspension (1) location is well protected inside the torque tube and can be easily taken out with quick connectors. To activate and deactivate the suspension, an electro vane is connected to the gas accumulator. The diverter valve (2) and the directly-connected relief valve are located above the torque tube, but still protected under a removable cover. These valves are located on the other side of the third function (3). th the directly connected relief valve (2a) and on the other side the 3rd function (3). The quick unlatch (not pictured) is located right next to the diverter valve (2). The torque tube cover is screwed on a metallic skeleton and can be easily taken off with just a wrench.
Specific parts for outstanding durability

Cast-steel parts in orange color
To achieve a stronger durability level, all pivot points were redesigned with a wider contact surface and are made from cast-steel material. These improvements decrease the pin´s wear and support the heavyt-duty applications. Finally, the H-Series Loaders feature specific pins equipped with a grease nipple in all pivot points. They are designed for a long lifetime and do not require replaceable bushings.
Easy to maintain
Greasing points integrated in the design pivot pin
The grease nipples are protected by the specific cast-steel parts design. This allows quick and easy access, without having to remove anything. The pivot pins have an eccentric design which makes sure that it will not rotate during loader movements, and it also keeps the grease in the pivot surfaces. This non-rotation of the pin is an important point to avoid any pin deformation and un-regular wear of the parts.
Suspension inside the torque tube
Suspension button inserted in the right-hand console when retro-fitted
The suspension button is integrated on the joystick (1). To activate and deactivate the suspension, the gas accumulator is connected to an electro vane. The suspension is connected to the lift cylinders, which move in and out to allow the boom to float, and thus provide a comfortable drive-in addition to protecting the material handled. A field-installed bundle can be ordered; a separated button will be delivered with the kit.
False-rod bucket cylinder
In order to be as productive as possible, fast bucket cycle times are important to dump the load from the bucket quickly. 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 use 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.
Shut-off valve open
Shut-off valve closed
A hydraulic shut-off valve is included in base with the H-Series Ag Loaders to ensure the loader does not lower suddenly. This allows the boom to be locked-out when someone is required to be located under the loader boom, for example, during service work on the tractor.
Parking lock for Australia

Parking lock storage solution
In addition to the shut-off valve, a parking lock, located on both lifting cylinders, is mandatory for use in Australia. The parking lock blocks the cylinder and thus prevents the front loader to lower when working under the front loader to conduct maintenance or serviceability work on the tractor for example. The front loader is equipped with this parking lock in base when ordering for Australia.
