Features Comfortable Operation Spacious operator station provides a comfortable working environment with easy-to-use, fingertip controls for the boom swing and auxiliary hydraulic functions. Compact Radius Design The machine’s compact design lets you work easily in confined areas. New to the D-Series, the 303.5D CR and the 304D CR feature a zero tail swing (ZTS) design, keeping the radius of the upper body within the width of the undercarriage.
Operator Station Superior comfort to keep you productive throughout the work day. Comfortable Working Environment Spacious and comfortable operator station with excellent visibility and legroom keeps the operator comfortable and reduces fatigue. Standard features include: • Reclining suspension seat with adjustable wrist rests. • Pilot operated controls on all services including travel levers and dozer functions. • Two post canopy design for better visibility to the work area.
Performance Powerful digging with precise control. Stability All four D-Series models feature increased stability over the previous series, while maintaining the compact radius design. This increased stability leads to more productivity and versatility through the use of heavier work tools and the optional long stick. Fast, Powerful Digging with Load Sensing Hydraulics High digging forces and fast cycle times deliver the productivity that your job demands.
Compact Radius, Zero Tail Swing Work in the tightest areas. Compact Radius The compact radius design gives greater machine versatility and the capability to work within confined areas. This allows the operator to concentrate on the work being done without having to worry about damaging the back of the machine or other job site obstacles. On the 305D CR and the 305.5D CR, the upper body stays within 140 mm (5.5 in) of the undercarriage. Zero Tail Swing New to the D-Series, the 303.
Coupler and Work Tool Options New coupler design and multiple work tools increase versatility. Couplers The D-Series couplers have a new design with a choice of either a mechanical pin-grabber or the new hydraulic pin-grabber quick coupler option. The new design uses a wedge to keep the tool secure to the coupler, reducing wear and maintaining a tight fit through the life of the coupler. The new hydraulic coupler option allows the operator to change tools without leaving the comfort of the cab.
Dozer Blade Standard dozer blade maximizes productivity. Simple Dozer Control with Float Function The dozer function is pilot controlled from inside the cab, providing smooth, proportional operation. The standard float function is enabled by pushing the lever fully forward into the detent position. Cleanup and backfilling is easier since the operator does not have to adjust the blade height during travel.
