Rotor Options: Some rotor options are not available in certain markets. ● Soil Rotor is designed primarily for use in soil stabili- zation. ● Combination Rotor is designed primarily for use in soil stabilization with a secondary application in light cuts of asphalt reclamation. ● Universal Rotor can be used for either reclamation or stabilization. ● Spade Rotor is designed for soil stabilization applications. PRODUCTION ESTIMATING The maximum cutting depth is 381 mm (15 in) for the RM300 and 457 mm (18 in) for the RM500B. The RM300 can mix up to 457 mm (18 in). In addition, the cutting width of their rotors is 2.4 m (8 ft). The following for- mulas allow you to determine the production in square yards (yd 2 )/minute or cubic yards (yd 3 )/minute. Production in square yards (yd 2 ) per minute

Gallons of additive (for units with pump and metering additive system) GPM = gal/yd 2 yd 2 /min Or, if required additive amounts are known, you can determine necessary travel speed as shown: GPM = yd 2 /min; yd 2 /min × 1.125 = ft/min gal/yd 2 Production in Cubic Yards (yd 3 ) per minute
