Product Information Sheet

All of the technical information on this product at a glance on the Product Information Sheet.


The 803 is the smallest Wacker Neuson excavator – but what it lacks in size, it makes up in strength. Its compact size, at just 700mm wide, makes it ideal for demolition and renovation work within buildings. The rubber tracks do not damage floors and it can easily drive through internal doors. Hydraulic functionality has been given particular attention. The standard auxiliary hydraulics permits the operation of various hydraulic attachments, such as the perfectly matched Wacker Neuson hydraulic hammer.

  • A truly professional performance: The tried and tested 3-cylinder diesel engine is a veritable powerhouse; efficient, economical and reliable.
  • One-way auxiliary hydraulics is a standard feature: Ideal for operating the perfectly matched Wacker Neuson hydraulic hammer.
  • The folding dozer blade always stays connected to the machine and can never be lost.
  • The extended hydraulic telescopic chassis with an 860mm external width gives added stability. It can be retracted to a width of 700mm in no time at all. Extremely robust.
