The 300 Series professional hole diggers from General Equipment are designed to handle heavy-duty digging projects from commercial fencing to upscale landscaping. A four-cycle, 3,600-rpm Honda GXV140 5-hp gasoline engine powers the series, and a Lo Tone muffler reduces operating sound. A resistor-type spark plug helps with starting. To increase operator control, a durable Magura twist-grip throttle is positioned to maximize hand and arm strength.
