Lavina 30 S7 Series Propano Kohler PCV740 747cc

- Powered by a Kohler PCV740 747cc propane engine producing 24 horsepower at 3,600 rpm, this 30-inch S7 Series planetary grinder steps up from the 25-inch Kohler model with a wider 30.8-inch working path and a heavier 926 lb machine weight — delivering more coverage per pass and greater grinding pressure on demanding commercial concrete jobs.

- A completely redesigned chain-driven planetary drive with no chain tensioner, a stronger timing belt, upgraded shafts, seals, bearings, and a two-piece aluminum belt housing with an inspection cover gives the machine a more durable and lower-maintenance grinding head than any previous Elite generation equivalent.

- Three 13.2-inch counter-clockwise rotating tool holders operate at 425 to 765 rpm, with four-position integrated weights that allow grinding head pressure to be dialed between 388 and 573 lbs — giving operators precise, on-the-fly control over cutting aggressiveness across a variety of concrete surface conditions and coating thicknesses.

- The fully sealed and dust-proof grinding head keeps all internal drive components shielded from fine particles and moisture throughout continuous operation, directly reducing wear-related downtime and making this machine well suited for extended commercial grinding and polishing projects.

- A redesigned frame with a significantly improved head angle during tool changes, rubber-bushed attachment points for reduced operator vibration, a multi-position fast-adjust handle, a Camlock E300 vacuum port, an onboard water tank cap, internal storage compartment, and an optional transport wheel make this one of the most contractor-ready machines in the S7 lineup.
