So I have a story about my "new" tiller. I bought it for only $50 and it was well rusted up, but spun ok. I knew it needed some TLC and some cosmetic work. I asked myself how the heck is the chain case lubricated? Well, I guess nowhere is the answer. I figured a small hole drilled into the case shouldn't do any harm. So, I turned it upside down so metal chips wouldn't get into the chain, and I drilled a 1/2" hole. With a strong flashlight I looked inside. It was dry as a bone. I got the proper lube (SAE20) and poured a quart into the hole. I let it sit for a week, and spun her twice a day to get everything good and coated. It spins real smooth now that it's lubed. So, hopefully I didn't mess anything up. I figured lubrication is a must! I cannot understand why the factory didn't put a fill hole in it. Someone out there in Cub country please tell me I'm not crazy. Thanks.
