WB146-5
Backhoe Loader
The WB146-5 incorporates numerous features and performance requirements while utilizing technologically advanced design and manufacturing processes. The result is a new range of backhoe loaders that are comfortable, convenient, reliable, productive, and easy to service.
Built for Strength
• At the core of every Komatsu backhoe loader is a heavy-duty one piece welded mainframe. • Dual swing cylinders provide high swing torque and are mounted high to reduce debris and damage. • The S-shaped backhoe boom provides outstanding strength and visibility. • Excellent digging forces, coupled with Komatsu HydrauMind hydraulics, translate into higher productivity. • The cast iron front end provides protection for the machine and also acts as an integral counterweight. • Komatsu heavy-duty backhoe buckets feature a dual tapered design for easy clean-out and incorporate heavy-duty components for longer life.
Built to Carry the Load
• A strong and productive loader with outstanding lift capacity and breakout force. • Komatsu parallel lift feature keeps the bucket or pallet forks level during both the lift and lowering cycles.
Built for Power & Speed
• Komatsu’s turbocharged diesel engines provide power and torque in reserve while maintaining excellent fuel economy. • Standard four-wheel drive and large tires provide the pushing power and floatation you demand. • Hydraulic brakes provide excellent stopping power and the rear axle differential lock can get you through the rough spots. • The Komatsu drivetrain is engineered to provide the power needed for loader applications and speed for road transport. • Komatsu’s exclusive HydrauMind hydraulic system, with over 43 gallons per minute of hydraulic flow, is designed for fast cycle times. The closed-center system provides power when needed and improves fuel economy.
Built for Comfort & Control

• The dual-entry operator features joy-stick controls, easy to reach and read instruments and switches, a spring suspension or optional air suspension seat, tilt steering wheel and a fully padded floor mat. • Loader and backhoe operation reach new levels of comfort and control with all new low effort proportional pressure control (PPC) joysticks. • Fingertip control of outriggers, from either front or rear facing positions, makes machine positioning a snap. • Backhoe controls are mounted on tilting towers with changeable control patterns. Adjustable wrist rests further maximize ergonomics and operator comfort.
Built for Comfort and Control Komatsu backhoe loaders feature a spacious and comfortable operator environment available in a ROPS canopy or enclosed quiet cab configuration.
