I need to find a part for my tiller (Identification number 77-50TL01) From the attached document on this post it is #26: 105046 Assy. Pinion Gear and Shaft. It broke in half while I was tilling today. It is saying it is discontinued and not available. Does anyone have one or know where I can get one? Thank you for any help you have. I hate to see this tiller go to waste now. It has barely been used and still looks virtually brand new. The extension tines have never even been used!!
