This listing is for a governor yoke and shaft, Snapper part #157-42101-03 and 157-42201-03.  They were removed from a Snapper 21 inch self propelled mower with a Wisconsin Robin model #WTI-125V-600002 4hp 2-cycle engine.  They may fit other models as well.  If you are not sure if they will fit your mower then please ask.  They are in good condition.  Payment within two days of purchase.  I will combine shipping on multiple purchases when possible.  If you are looking for a part that I don't have listed please ask, I might have one.  Thanks for looking!
