Weld repairs on heat treated steel gears is not adviseable. Gears are hardened to a specified depth (carburized) while the center areas remain
relatively ductile and soft. Welding up the pit
would destroy the hardness properties of the tooth. Also, during welding a thin layer of fine grained and very hard martensite is formed at the bottom of the weld heat affected zone. Tractor
operation may create stresses high enough to cause
a crack in this layer of martinsite. Get another bull gear for your M, use the old one for a boat anchor.
