The LR 634 Litronic maintains the proven hydrostatic drive system found on the previous LR 632 model. Weighing from 45,760 to 50,045 lbs., the new unit is powered by a Liebherr D 934 L Tier III-compliant diesel engine generating 184 hp at 1,800 rpm. Bucket capacity ranges from 2.49 to 3.14 cu. yds. Optimal weight distribution with long track frames results in high tipping load and bucket loading capability. In addition to true counter-rotation capabilities, electronic control further optimizes efficiency in both travel and loading. Turning is now speed sensitive, while the hydraulic response speed has been substantially improved. A larger operator's cab offers high visibility, fully adjustable single-lever joystick control, standard A/C and an air ride adjustable seat.
