Note: For the gaskets on the gear case cover and hubcaps, our Amish shop uses round foam from hardware and home centers for caulk backing and stuffing around doors and windows. The grooves in the gear case cover and hubcaps allow the foam to seal down. 

Our Amish companies have been making and sourcing replacement parts since 1950 for what many consider antique or junk farm machinery today.  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 being manufactured and dealers no longer stock parts, it is challenging 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 this old-time horse-drawn farm machinery.

A note on shipping costs: If you need only a small part, such as a bolt, nut, or shim, please contact us to place your order; otherwise, the shipping calculator assumes you will order several parts from this section at the same time.
 
These replacement parts carry minimal markup for us, primarily when we sell a single item, such as a bolt and nut. To defray processing time and costs, credit card fees, and labor to pack and transport to the post office, regardless of shipping costs.
