Singer Part # 181843M is a replacement metal feed dog designed for many vintage Singer home sewing machines. This is the metal version of the common rubber-tipped feed dog (part # 181843) used in several mid-to-late 20th-century models. The feed dog is the toothed component beneath the presser foot that grips and moves fabric through the machine during sewing, ensuring even stitch formation and consistent seam quality.

Performance & Benefits:

Metal feed dogs are often preferred for their durability over the original rubber-tipped versions, which can become brittle, sticky, or worn over time. The solid metal construction provides consistent fabric gripping power and long-lasting performance, making it an excellent upgrade for machines originally equipped with rubber-tipped feed dogs.

Important Installation Note:

When switching from a rubber-tipped feed dog to this metal version, slight modifications or height adjustments to the feed bar may be necessary to ensure the feed dog aligns correctly with your needle plate. The metal feed dog may sit at a slightly different height than the rubber version, so proper adjustment is essential for optimal fabric feeding and stitch quality.
