Briggs & Stratton Corp. expects to launch 40 lawnmower models in 2013 across its dealer network, more products than in the past five years combined, according to Robert W. Baird & Co. Inc. financial analysts.

Analysts for Milwaukee-based Baird reported Briggs & Stratton’s plans in a note to investors Tuesday, after Baird hosted a recent investors meeting with leadership of the Wauwatosa-based maker of small engines and outdoor power equipment.

A Briggs & Stratton (NYSE: BGG) spokeswoman confirmed the number of product launches, but a company executive wasn’t immediately available for comment Tuesday afternoon.

The aggressive plan for product launches this year appears to be a result of Briggs’ move to pull some of its lawn and garden products from national mass retailers, which “freed up internal resources for more focused product innovation efforts,” Baird analysts wrote.

“Management expects to generate $80 million to $100 million of free cash flow from reduced working capital related to the mass retail products business,” Baird wrote.

I wrote about Briggs’ decision to exit mass retailers last August. The company’s engines segment continues to serve lawn and garden equipment manufacturers that provide products to these retailers, and Briggs & Stratton still sells portable and standby generators and pressure washers through the U.S. mass retail channel.
