Lavina 31 S7 Series Propano Vanguard 993cc

- Driven by a Vanguard 993cc propane engine producing 35 horsepower and 26 kW of output, this 31-inch planetary grinder delivers the torque and grinding pressure needed to power through the most demanding concrete surface preparation and polishing applications without relying on grid power.- A completely redesigned chain-driven planetary drive features a stronger timing belt, upgraded shafts, seals, and bearings, along with a two-piece aluminum belt housing with an inspection cover — all working together to extend service life and reduce the frequency and cost of routine maintenance stops.

- The fully sealed and dust-proof grinding head shields internal components from fine particles during operation, while three 13.2-inch counter-clockwise rotating tool holders deliver a working width of 30.8 inches and adjustable grinding pressure ranging from 392 to 794 lbs depending on weight configuration.

- A redesigned frame with repositioned weights, rubber bushings at all head attachment points, and a multi-position handle with faster adjustability significantly cuts down on operator fatigue and vibration during extended use — while a built-in gravity-fed water system with a 5.2-gallon tank supports wet grinding applications.

- A built-in storage compartment, adjustable magnetic LED lights, a Camlock E300 vacuum port for dust extraction hookup, and compatibility with a standard 20 lb propane tank round out a machine engineered from the ground up with contractor productivity and ease of use in mind.
