Our Amish company has been manufacturing replacement parts since 1950 for Amish communities that still use and maintain vintage farm equipment. 

In the late 1800s and early 1900s, nearly every farm used the same equipment, creating ample demand for replacement parts.  As most farmers modernized throughout the 1900s, the Amish continued to rely on horse-drawn equipment, as many still do today.

Since this equipment is no longer in production and dealers no longer stock parts, it isn't easy to keep this vintage farm machinery operational. Both Amish and vintage farm machinery implement enthusiasts scour junkyards, farms, and tree lines in search of these long-abandoned implements for restoration.

Cottage Craft Works.com travels deep into the back roads to find Amish companies that still make replacement parts to maintain and restore old-time horse-drawn farm machinery.
