Caterpillar soil stabilizerCaterpillar introduced the RM-300 and RM-500 rotary mixers as replacements for the RM-250C and RM-350B reclaimer mixers, respectively. At 350 and 540 horsepower, the RM-300 and RM-500 utilize Tier 3 Caterpillar C11 and C15 engines with ACERT technology. With the new rear wheel-assist option, larger rear tires, and the universal rotor option, the RM-300 is now better equipped for those tougher jobs requiring maximum-depth soil stabilization in moisture content such as lime slurry.
