We always advocate using genuine parts, and all the parts on our website are genuine except for rare circumstances where genuine parts are no longer available. Genuine parts generally are a better fit, are higher quality, and last longer than non-genuine parts to ensure your Hayter runs to its full potential. When buying a Hayter lawnmower you have invested in a high-quality machine, and using genuine parts is the best way to ensure your Hayter continues to perform well.
