You don't have to sacrifice powerful digging forces to get parallel lift. The 644K Powerllel™ delivers the best of both, so you can have your loader and forklift, too. Unlike traditional tool-carrier linkages, our innovative design allows load forces to work with, not against, the boom, for big breakout force, even in difficult digging. Impressive torque throughout the entire dump and rollback range enables the 644K to excel at a wide variety of material-handling tasks.

Features & Benefits


PowerTech diesels maintain impressive torque reserves for great boom and bucket speeds in and out of the pile, delivering heaped loads — even in wet- or hard-packed material.


The in-tank filter with large element traps that hold contamination allow for cleaner oil, a cleaner hydraulic system, and less maintenance. Service intervals are extended to 4,000 hours.


The hydraulically driven fan runs only as needed for efficient cooling. Helps conserve fuel, too.


Joystick F-N-R selector provides convenient direction and full-range gear changes, and includes an innovative Quick-Shift feature for pushbutton gear changes.


Automatic differential lock engages as soon as a tire begins to slip. It's ideal for inexperienced operators or applications requiring high traction, such as stockpiling silage, plowing snow, and handling pipe.


Vertical spin-on filters allow quick, no-spill changes. Extended 500-, 2,000-, and 4,000-hour engine, transmission, and hydraulic oil-service intervals help reduce operating costs.

Z-Bar linkage

High-Lift Z-bar loader linkage option provides high bucket breakout forces, good rollback to carry loads without spilling, and very solid stability with lighter materials. High-Lift is recommended for high-sided truck and hopper applications.

Sealed-switch module

A backlit touchpad sealed-switch module controls keyless start and 24 other machine functions, allowing the operator to activate boom-height kickout, return to carry, and return to dig from the seat.
