Upgraded weights and a multi-position handlebar make tool changes easier and give better control with less vibration.

Does the 31G S7 replace the 32G Elite?

Yes. Lavina no longer manufactures the 32G Elite and lists the 31G S7 as its replacement in the propane line.

Which engine does it come with?

A 35 hp propane engine: the Vanguard 993 cc on the L31GS7 or the Kawasaki FX1000 on the L31GFXS7. Your Latux rep confirms which version is available for your order.

How much grinding pressure does it apply?

392 to 690 pounds, or 794 pounds with the optional 75 pound extra weight, with the tool holders turning 425 to 765 rpm.

What dust extractor should I pair with it?

A Lavina V32GE propane extractor keeps up with the head and captures the silica it produces, with no outlet needed on site.

How do I buy it, and what about freight?

The 31G S7 is sold by quote. Call or message your Latux rep for current price, freight, and lead time. The MSRP shown is for reference.
