Wheel Loaders - John Deere 644J Z-Bar Wheel Loader
   
Productivity

An impressive torque reserve of 55% provides extra power when you need it.

When rpms drop below 2200, horsepower actually goes up.  The John Deere Power Bulge advantage helps maintain good boom and bucket speed into the pile.  For quicker and easier bucket fill.

You won't find a smoother shifting loader.  The powershift torque-converter transmission employs smart-shift technology to continuously evaluate speed and load conditions, and adjusts clutch-pack engagement to suite.  For extra productivity without extra effort.  

Comfort

Choose from single-lever joystick or two lever fingertip pilot operated controls.  Both include John Deere's innovative Quick Shift feature that allows pushbutton gear changes.

Backlit pushbuttons in the sealed touchpad allow fingertip control of numerous functions.  No tools required to adjust boom height kick-out, return-to-carry, or return-to-dig.

Standard air-ride sear adjusts multiple ways for extra comfort.  All-around visibility is unobstructed and 11 automotive-style louvers provide effective airflow to help keep the view clear, the cab comfortable.

Uptime/Service

Quad Cool™ places the radiator and transmission, hydraulic, and air-to-air coolers in a separate compartment for extra efficiency and decreased debris buildup.  Optional reversing fan back-blows every 30 minutes to help keep cores clean.

All daily service points including fuel are on the left side for quick and convenient ground-level access.

Extended engine, hydraulic, and transmission service intervals contribute to low daily operating costs.

If something goes wrong, and advanced monitor gives easy-to-understand diagnostic messages and even offers possible solutions to help get you back up and running quickly.
