Lawn, Garden & Off-Highway Case Studies

Billions of dollars are spent in the U.S. each year on agricultural machinery. Powder metallurgy (PM) is strongly represented in the agricultural industry and also assists in building and maintaining machinery from basic lawn and garden care to heavy off-highway machinery.

The case studies below are a collection of award-winning parts submitted to the Metal Powder Industries Federation’s annual PM Design Excellence Awards competition in the Lawn, Garden & Off-Highway category.
