ET42

ET42 - Innovative excavator offers power and performance
The ET42 tracked excavator offers large machine features in a smaller package. This 4.0-ton class machine is designed to assure that the performance and features offered meet the demands of the operator. Key innovations include enhanced visibility, operator comfort features and a linkage system that offers greater digging depth and dumping height, all contributing to a productive, high performing excavator.Three-point kinematic bucket linkage system enables a 200-degree bucket rotation for excellent breakout force, greater digging depth and dumping height

Low profile hood and large windows provide an exceptional view the front of both tracks and the offset boom provides a complete view of the boom, attachment and work area Load Sensing Flow Sharing system allows consistent and precise control regardless of load and offers comfortable and fatigue-free joystick control

Fuel efficient 46-hp Perkins diesel engine offers class-leading power and performance Precise work results with Load Sensing Flow Sharing

Load Sensing Flow Sharing allows precise control regardless of the load to be moved. The machine adapts to the load and the joystick movements remain the same for the operator.

Powerful hydraulics for versatile applications
With the ET42's four auxiliary control circuits, versatile attachments can be used. With these, the mini-excavator can be applied for many different uses. Attachments can be quickly changed thanks to the new pressure release switch. The mini-excavator can be used at ambient temperatures of up to 45 degrees without compromising performance.

Comfortable operation and optimum visibility
The intuitive operating concept of the ET42 allows easy and comprehensive control of the excavator. Using a joystick, 3.5-inch display, Jog Dial and keypad, you can operate the machine, control the auxiliary hydraulics, or set oil levels. A 7-inch display is an available option. Cab offers standard air conditioning and the unique four position windshield provides fresh air and easy communication on the job site. The windshield wipers and their wipe direction were adjusted such as to prevent any visibility restrictions for the operator. The Bluetooth hands-free system (optional) and USB charge function round out the utmost comfort.

Active Working Signal for even greater safety Workers on the construction site can tell if the excavator is in operation thanks to the Active Working Signal (AWS) attached to the engine hood. The AWS lights up red when the joystick support is pressed down and the excavator is ready for application.

Low-emission, powerful engine The ET42 is equipped with a powerful diesel engine with integrated DPF (diesel particulate filter). The engine fulfills the standards of exhaust emissions stage 5 and thus ensures minimum emission of pollutants.

Due to the thermal management developed by Wacker Neuson, not only is the service life of the diesel engine increased, but the performance of the cabin heating as well. The exhaust system, pointed upwards, minimizes potential injury to persons and damage to objects.

The ET42 is also fitted with a large engine hood. This makes the servicing points easy to access.

Well protected cylinder
The lifting arm cylinder is protected from damage by a piston rod protector made of synthetic material. This saves repair costs and time. Protection is also optionally available for the dipper stick and dipper cylinder.

Swiveling dozer blade and flawless stability
When backfilling, the machine doesn't have to be reset as often, as the dozer blade can be swiveled to a straight position or up to 25 degrees to the left or right (optional). In the floating position, the dozer blade applies constant force on the cutting edge. This way, the blade position has to be adjusted less often.

The external track rollers give the machine a high degree of stability, especially for lifting heavy loads.
