My project today was to do the first oil change on my Toro rear engine ZT mower. I told my wife that I was going out to work on the mower and to get the bandaids ready. Oil drain was a piece of cake by just pushing on a hose to a quick turn fitting, turn it and let it flow into a jug on the ground. Next was to change the filter. It was a small spin on filter but spun on 90° to the frame and surrounded by lots of sharp frame parts and plastic fender. I couldn't find and easy way to get to it. I was finally able to get an old steel band swivel wrench on it and discovered that the filter was welded on with nuclear weapons. After much swearing I finally got it to budge. Then finally getting it to move another smidgeon after repositioning the wrench many times until it finally spun off. I have never a filter put on that tight (thank you Toro). After getting the filter off I noticed that the plastic fender had turned my right forearm into what looked like a meatball sandwich. No pain and little bleeding but geez. Another situation where the engineer who designed this shit never had to fix anything.
