WA475-10

Extensive customer feedback and years of testing went into the design of Komatsu’s versatile new WA475-10 wheel loader. Ideal for quarry, waste, infrastructure, forestry, and non-residential construction applications, the newly designed WA475-10 with next-generation technology was developed to support customers’ needs for improved productivity and lower fuel costs.

The WA475-10 introduces the Komatsu Hydraulic Mechanical Transmission (KHMT) to Komatsu wheel loaders. This new transmission improves fuel efficiency and provides the operator a wheel loader that is easy to operate and quick to respond in the work environment.

Features

Komatsu hydraulic mechanical transmission (khmt)

The KHMT allows the WA475-10 to achieve up to 30% increase in fuel efficiency (tons/gal), while at the same time utilizing an engine with 22 more horsepower than the WA470-8.

Patented independent work equipment control

The Independent Work Equipment Control simplifies operation and reduces fuel consumption by separating the accelerator pedal from the speed of the work equipment.

Redesigned ROPS/FOPS cab and operator environment

The operator environment has been redesigned from feedback from the field. Visibility has been improved with the addition of glass in the lower position of the front corner of the cab and the lower area of the side doors. A 5-way adjustable console with integrated switches allow for a comfortable posture for various sizes of operators. The WA475-10 also utilizes ergonomic positioning of switches, heated remote mirrors and a multifunction audio system that includes AM/FM radio with AUX, USB, and Bluetooth wireless technology.

One piece electronic tiliting engine hood

The engine hood on the WA475-10 can quickly be opened with a switch located on the left side of the machine near the battery box.

HD front and rear axles (Standard)

The WA475-10 is equipped with new Heavy Duty (HD) axles as standard equipment, 775/65 R29 wide tires or solid tires can be used for extreme or severe applications.

High resolution 7-inch color LCD monitor

The machine monitor displays various machine information and allows for various settings of the machine. The LCD monitor is a 7-inch color TFT-LCD and displays maintenance information, operation record, Ecology Guidance record, and other machine data. The Command Selector is used to select various user menus on the LCD screen and adjust the machine settings.

Komatsu auto idle shutdown

In order to reduce idle time and save fuel cost, the Komatsu Auto Idle Shutdown function will shut the engine off and apply the parking brake and hydraulic lock after a preset idle time limit. This time limit can be set by the operator or service technician and may range from 3 minutes to 60 minutes.

Operator seat with electronic pilot control (EPC) levers

A new air suspension seat provides enhanced support on rough roads and dampens machine vibrations, providing a more comfortable ride for the operator. An EPC lever console is integrated in the seat and moves with the seat. The console has 5 different adjustments for optimum operator comfort. A secondary F-N-R switch is incorporated near the work equipment lever configurations on steering wheel equipped machines. A heated seat is standard.

Full front and rear fenders (Standard)

The WA475-10 has a full front and rear fenders as standard. The plastic rear fenders raise when the engine hood is opened, giving the technician generous access to the engine compartment. Mud flaps are also included on the rear fenders. The front fenders feature an extension that minimizes debris hitting the machine when operating in reverse.

Rear view monitoring system

The operator can view the rear of the machine with a dedicated full color monitor that is located on the right front cab pillar . This monitor is positioned at eye level, at the same height as the rearview mirrors. The monitor can be set to be always on or only on when the loader goes into reverse. Visual reference guidelines offer additional convenience.

Remote bucket and boom positioner

The operator can set the bucket angle and remote boom positioner from the cab. Both upper and lower boom positions are adjustable in the cab with the push of a button. The bucket positioner can memorize three horizontal settings, allowing the operator to easily change attachments without having to reset the bucket position. In each horizontal setting, the operator can adjust the setting with the switch in the cab. This can help save the operator time when changing attachments.

Swing-out type cooling fan

The cooling fan swings out from the engine compartment for ease of cleaning. The coolers feature wider spacing of the cooling fins to reduce clogging. Auto-reversing intervals for the fan can be customized through the monitor panel.
