These are VERY strong little units. Gas unit, EPA certified 13.5 HP Briggs.

This 1150kg mini excavator is a robust piece of equipment built for serious work despite its compact size. Powered by a 13.5 HP Briggs & Stratton engine, it comes EPA certified for environmental compliance.
The unit arrives fully assembled and ready to operate with simple key start ignition. A hydraulic thumb is included for enhanced digging precision, though a quick attachment system is not part of this package.
With a maximum digging depth of 1600mm (5.24 feet), this little excavator punches above its weight. Its compact dimensions of 2550*950*1350mm make it ideal for tight workspaces while still delivering the power needed for demanding tasks.
