Wacker Neuson’s ET42: big features in a small machine

Wacker Neuson excavator

To create its new 4.2 ton excavator, Wacker Neuson packed large machine features into a smaller package.

The new ET42 is an ideal choice when more power is needed for digging in confined areas such as utility or landscaping applications.

The conventional track excavator was designed with voice-of-customer research to develop a machine that delivers the performance and features required to meet operator’s demands.

One of the main results of the ET42 customer research was the request to improve visibility.

So, Wacker Neuson engineers revised the low-profile hood design and expanded the side window glass down to the lower portion of the cab, allowing the operator to see the front of both tracks. This, combined with the large windows and the offset boom, provides a complete view of the boom and attachment, as well as the working area.

The 4-ton excavator offers the same three-point bucket linkage that is used on the manufacturer’s larger models. The unique kinematic linkage system offers a 200-degree angle of rotation, which combines ample breakout force with a wide range of motion.

The linkage also provides greater vertical digging depth, which can be helpful when excavating next to walls, and can rotate the bucket further to keep the load more secure before dumping. 

To boost productivity, the excavator is available with a hydraulic quick connect system that allows an attachment to be changed in seconds without leaving the cab.

As well, a diverter valve on the auxiliary hydraulic line allows operators to switch between thumb and another attachment, such as a hydraulic breaker, without disconnecting the hoses. 

Wacker Neuson also considered operator comfort “from top to bottom” when designing the new machine. 

The dual flange rollers in the undercarriage improve stability when digging and provide a smoother ride with less vibration. A total of eight large tie down lugs make securing the ET42 for transportation quick and easy. 

In the cab, the excavator features standard air-conditioning, as well as a unique four-position windshield design that allows for fresh air and easy communication. 

The unit also includes a cell phone charger and holder, air-cushioned seat and adjustable armrest.

The floor is ergonomically designed so the operator’s feet rest at a comfortable angle. Furthermore, all controls are all conveniently located, including an electronic ISO/SAE changeover switch right within the operator’s reach. Additionally, the 9 cm colour display provides all the information the operator needs in a clear, easy-to-read display.  

The ET42 is available in cab or canopy models with LED working lights and an optional angle blade or Wacker Neuson’s exclusive, redesigned Vertical Digging System (VDS).
