Updated Oct 5, 2010

Rolling Meadows, IL, July 27, 2006- Komatsu America Corp. announced the WB146-5 and the WB146PS-5 Backhoe Loaders with Tier 2 Engine.  Both machines have an operating weight range of 16,090 lbs and with a large loader bucket of 1.25 yd3 they represent a new generation of backhoe loaders that are reliable, productive and easy to service. 


The WB146-5 gets its power and fuel economy from a turbocharged Komatsu S4D102LE-2 engine with a flywheel horsepower of 88 HP to drive Komatsu’s exclusive HydrauMind hydraulic system delivering precise power and precision.  The drivetrain includes a 4-speed synchro-shuttle transmission with standard four-wheel drive for greater traction in soft soil applications.  The WB146PS-5 includes a full PowerShift transmission with twist grip gear control. 


The WB146-5 features a heavy-duty one-piece welded mainframe for exceptional stability and durability.  The new “S” shaped backhoe boom is narrower and stronger for superior visibility, increased lifting capacity, enhanced truck loading and excellent breakout force.  Combine this with a telescopic arm and the backhoe can achieve digging depths up to 18’4″. 


The parallel lift linkage for the front loader keeps the load level throughout the lifting and lowering cycles for safe and productive work flow, and with the optional hydraulic attachment coupler you can add forks for tool carrier operations.  The slim loader arms further enhance operator visibility and allow for easier truck loading.  The heavy-duty cast iron nose guard provides both protection for the machine and also acts as an integral counterweight. 


The operator environment is designed for maximum comfort and control and is available in either open ROPS canopy or an enclosed cab with dual entry.  The climate-controlled cab has 10 vents for maximum air circulation while its round shape and one-piece rear-opening window further enhances operator comfort and visibility.  The multiple seat adjustments accommodate both large and small operators and PPC excavator and loader controls provide for greater ease of operation.
