A series of mini hydraulic excavators — the 303.5D CR, 304D CR, 305D CR, and 305.5D CR — are versatile, compact-radius machines designed to work comfortably in confined spaces. Model designations reflect operating weights (3 1?2 to 5 1?2 tons), enhanced stability, redesigned work-tool coupler, and engines that meet Tier 4 Interim regulations. The boom features a curve design for digging flexibility and fabricated-box construction for strength and durability.
