The STI-4438LP Propane machine has the same robust design as the model STI-4430, but is powered by a 38HP Kawasaki propane motor. Quite unexpectedly for its weight and size, this grinder is extremely easy to operate due to the smooth operation of the STI rotary gear system. It features a movable pocket weight system for multiple applications and is recommended for projects greater than 20,000 SF (1858 m2). Its variable speed drive easily adapts to different grinding or polishing conditions for concrete, terrazzo, marble, and stone applications. Available in 230V or 480V. Uses eight tool plates (included).
