Model 803 Dual Power mini excavator runs off a standard diesel engine or it can easily be connected to an electro-hydraulic pump, allowing emissions-free operation. In the conventional operation mode, the 803 is powered by a 13-hp diesel engine, providing enough power for breaking applications. When connected to the HPU8 electo-hydraulic pump, it runs emissions-free. Wacker Neuson. www.wackerneuson.com. WOC Booth O31708
