W285, 8.5ton small excavator
W285 is a 8.5ton small excavator with 0.36 cubic meter bucket. Original Yanmar engine supplies enough power for this size excavator. Rexroth hydraulic pump and valve provides perfect working performance. Air conditioned cabin and a dozer are both standard equipped. The W285 hydraulic excavator delivers superior performance and comfort while reducing your operating costs. The large spacious cab provides a comfortable work area. Intuitive seat-mounted controls are easy to use for greater job accuracy and efficiency.

Benefits and features
1. Original Yanmar engine
    Model No.: 4TNV98T-SFN
    Rated power: 53.1kw/2200rpm
    Displacement: 3.319L
engine gives higher power and maintains strong performance at high altitude. High digging forces give power through even the most compacted ground with smooth control and responsive hydraulics that deliver productivity that our customers demand.



2. Hydraulic systems
The W285 excavator uses the Rexroth or Toshiba hydraulic pump and valve. The Smooth responsive hydraulics gives the level of control demanded by the customer in any application, from fine grading and dozing to backfilling. Powerful bucket and stick digging forces combined with fast cycle time result in world class productivity and performance. Automatic two speed function improves jobsite maneuverability with precise control by balancing travel speed with the torque needed for turning and travelling on inclines. Dozer blade float function enables easy ground leveling for landscaping and finish grade applications as well as more efficient jobsite clean-up.



3. Cooling system
The high-ambient cooling system features a fixed-speed fan and a side-by-side-mounted radiator and oil and air coolers for easy cleaning.



4. Spacious cabin
A large, spacious cab provides operator comfort and improved visibility. Joystick controlled swing boom and auxiliary switches clear space on the floor giving the operator plenty of foot and leg room. An intuitive cab layout for ease of operation reduces operator fatigue.



5. Strong undercarriage
The standard track offering is a 450 mm (18 in) triple grouser track. Grease-lubricated track links, split master link and sealed track rollers reduce owning and operating costs. Steel tracks provide optimum stability when lifting over the side. The X frame is produced by World with high tensile and strength steel plate.



6. Dozer is equipped
A dozer is standard equipped. It improves the various versatility of the W285 excavator.
