Inboard planetary axles

Funk™ inboard planetary axles are as tough as they come

When workloads are heavy and conditions are harsh, your equipment needs axles that can handle the pressure. Our family of axles has proven itself over and over — and under the most stringent conditions. Their strength and durability have made them a fixture in the forestry, ag, oil field, mining, and construction industries, as well as in a number of specialty applications.
Our high-torque, low-speed axles are designed using a building-block concept that enables us to offer thousands of configurations and, essentially, to custom-build an axle to fit your torque and load requirements precisely. All John Deere axles are non-steerable, and are built strong to contribute to the rigidity of your equipment’s frame. And because they offer wide bearing spacing, they give you additional track width flexibility.

We’re committed to adding value to your equipment and giving you a competitive edge. Our inboard planetary axles are one example of that commitment.

HMD Transmissions

Durable and dependable hydrostatic motor-driven (HMD) transmissions

Funk™ HMD transmissions are equipped to operate with high-tech hydraulics. They provide the electronic controls you need for heavy-duty equipment such as dozing machines, motor graders, railway vehicles, sweepers, pavers, and virtually any other application where a controlled travel speed is critical.

The 18000 HMD — for high-power needs

The most popular model in our HMD lineup, the 18000 offers a generous 149-kW (200-hp) rating for powerful applications. The design includes an integral lube pump that completely lubricates input splines and bearings, increasing the life of the transmission. Two high-gear and five low-gear ratio options produce the speeds appropriate for equipment in the forestry, construction, railroad, mining, and ag industries.

HS17000 HMD — shift on the go

The HS17000 is a two-speed powershift transmission capable of shifting gear ranges while in motion. The speeds are obtained through the use of electrically controlled solenoids and hydraulically actuated multiple wet disc clutches.

Powershift transmissions

Reliable powershift transmissions

Customers trust you to provide reliable, high-performance equipment with the most up-to-date components. We produce powershift transmissions that help you meet that need — and we do it with personal, attentive service, no matter what size your operation.
Our powershift transmissions are available in both torque-converter and direct-drive options, covering applications in ag, construction, forestry, mining, aircraft ground support, railroad maintenance, and other industries. Mounting options include engine, midship, and remote. Funk™ powershift transmissions are built in one of the most advanced power transmission manufacturing facilities in the world. Our leading-edge technology means your OEM machines have smoother shifting, along with fingertip speed and directional control. This enables the operator to get more production out of the machine, more quickly and with less effort.
Best of all, we still believe in personal service, so when you have a specialty order or other unique need, we respond. Our application engineering group will work closely with you, providing a detailed concept performance analysis of your vehicle.

HMD Transmissions

A modular approach to building pump drives

With thousands of combinations, gear ratios, hydraulic pump adapters, mounting options, and more — we can configure a pump drive to your design specifications. Built for quiet operation, our pump drives are available in four series up to 708 kW (950 hp) and equipped to operate as independent mount, direct-engine mount, or clutch-driven units. Adapters are available in a variety of engine housings and flywheel sizes.

The advantages of customization

With more than 50 years of experience behind us, and our unique combination of custom design and modular manufacturing, John Deere can offer highly durable and reliable pump drives. Whether you need a new pump drive or support on an existing drive, our modular assembly system lets us get you what you need fast.

You will also appreciate our integration support network. Our application engineers can help you select the options that best fit your needs. We also offer dedicated OEM service and long-term aftermarket support.

Add up all the advantages — including our many custom options — and it is easy to see why Funk pump drives are the choice of so many equipment OEMs.

Planetary gear drives

We offer a complete line of Funk planetary gear drives for OEMs in the ag, construction, manufacturing, marine, mining, and petroleum industries. Applications for these durable drives include conveyers, cranes, crawlers, excavators, road rollers, track vehicles, winches, and many others.

You can count on Funk planetary gear drives to deliver durability, performance, and superior engineering. Our drive designs include various ratios of input gear reduction sets, along with single and multiple combinations of center-section planetary gears that drive power through output arrangements to accommodate a wide range of applications.
