Sears Riding Mower Oil Change ...

Your gonna make a mess. Just accept that. Depending on engine position (and I am NOT familiar with your machine) sometimes a makeshift funnel can be used/made. I have even made them from an old jug (think antifreeze) where I have cut one edge of the rounded jug off to make a ramp for the oil to flow. Lots of newspaper laid under the machine. Even a piece of heavy cardboard formed into a "V" can sometimes help.

I use a funnel and an empty 1 or 1/2 gallon bleach bottle to drain the oil out as neatly as possible. For you mower the drain tube may be long enough to drop into the container. It should hold at least 2 quarts. Try to have the drain on the low side of the mower. If the ground is level, run the opposite side of the mower up on a plank. Run the mower for a few minutes to warm up the oil. If already warmed up by running or after mowing, be careful, hot oil can burn you. Pop the cap off the oil drain valve and put the tube on the nipple protruding from the valve. Put the end of the tube in your container. Open the valve by pushing in slightly and then rotating it counter-clockwise. The oil should start flowing out the tube. Let oil drain fully. I usually go away and come back in 15-30 minutes. Close the valve by pushing in and rotating it clockwise to the closed position. Remove the hose and container. Fill carefully with the correct amount of oil (3 pints?).
