The PC300LC-8M0 is designed to efficiently and productively carry out a wide range of earthmoving, excavation and rock breaking duties. As with all our construction excavators, key components are designed and manufactured by Komatsu to work together in an integrated package. And it comes standard with our Komtrax remote monitoring and location system, backed by our Australia-wide service and support network.
