The F4 ECO LITE from Tornado Global Hydrovacs has a 12-cubic-yard mud tank and holds 1,400 gallons of freshwater. This unit is over 7,000 pounds lighter than the company’s older models and offers nearly triple the payload. The boom has a 342-degree rotation and a 26-foot reach. The F3 ECO LITE is a 10-cubic-yard, 1,200-gallon water tandem-axle unit that also more than doubles older payload capacities. With an 8-inch boom and a 3,800 cfm blower, although smaller, it’s still robust and powerful. 877-340-8141; www.tornadotrucks.com
