New Tier 4-compliant DX63-3 and DX85R-3 excavators have been upgraded with several conveniences that provide operators with high-precision controls, greater force, and overall enhanced productivity. Available for the first time on the manufacturer’s excavators in this size class, the blade float feature provides operators the versatility to smoothly grade, level, or backfill material. Both new machines come standard with Auto-Shift travel, which shifts the excavator out of high range or low range and back automatically. Doosan. WOC Booth C5487
