CRAWLER LOADERS DRIVETRAIN Multi-tasking made easier We’ve enhanced hydraulic response for faster boom, bucket cycle times, and improved metering during fine grading. For more than 25 years, full-featured hydrostatic drivetrains have provided John Deere crawler owners with unsurpassed operating ease and flexibility. Now with our new optimized power management system, you’ll feel more power when you need it, and an overall better engine/tranmission performance match. That means track motion rema

Just set maximum desired ground speed and the crawler does the rest. As the loads change, the drivetrain responds, automatically powering up or down to maintain peak engine rpm and efficiency. Low-speed working range was increased to 4 mph to allow most performance needs to be met in one speed setting for faster cycle times. Innovative control system keeps these loaders tracking straight in either direction or on level ground or steep slopes. Delivers smooth, predictable turns under full load,

Maintenance-free rubber isolators in the track-frame suspension absorb shock and vibration for smooth moves and enhanced gradeability. Lubricated chain keeps lubricant between pins and bushings sealed in, abrasives out for long life. Rollers and idlers are sealed, too. Generous track on the ground, oscillating track frames, cushioned pivot shaft, and 52-degree bucket rollback help keep the bucket heaped when transporting material on slopes or across rough terrain. 8-9
