Changing the Oil in a Simplicity Lawn Tractor – Step by Step
Step 1. Warm Up the Engine
The first step in changing the oil in your lawn tractor is to run the engine until it is warmed up. Usually about 10 minutes or more should do it.
Step 2. Position the Mower on a Level Surface
Move your lawn mower to a level surface. This is important for assessing the final fill oil quantity, and so that the oil drains properly.
Step 3. Turn off Engine and Open the Hood
Make sure the lawn mower is off, and secured so that it won’t roll away!
Step 4. Clean the Oil Fill and Filter Area
Clean any sand, dirt, grass, or other debris away from the oil fill port (dipstick) and oil filter locations. This will help avoid getting unwanted contaminants into the engine oil.
Step 5. Remove the Dipstick
Removing the Dipstick (which is also the oil filler port cover) will help the oil drain out faster.
Step 6. Locate the Drain Hose
Many lawn tractors have an oil drain hose, if your does, locate it and position it so that it is over a drain pan. If your tractor does not have a drain hose, position a drain pan under the oil plug bolt on the engine (located under the oil filter).
Step 7. Remove the Drain Plug
Use a wrench to remove the drain plug. Oil will begin draining out. Allow all of the oil to drain out into the drain pan. Once all or most of the oil has drained out, re-install the drain plug. Tighten it securely.
In my case, the drain tube uses an 18mm and 16mm wrench to loosen and remove the drain plug.
Tip the drain tube up to remove the drain plug.
Then put it into a drain vessel when tipping the tube down to drain the oil. Allow the oil to drain out. Eventually it will slow to a drip, then replace the drain plug.
Step 8. Remove the Oil Filter
Unscrew the oil filter. If the filter is too tight to remove, use the appropriate 65mm oil filter wrench. A small amount of oil will drain from the oil filter port as well. Catch the oil with the drain pan or a rag.
If your father-in-law tightened the filter extremely tightly the last time with his man-hands (like what happened to me), then you may need to use a filter remover or pipe wrench to loosen the filter.
Once you remove the filter, another 1/2 cup of oil will drain out, so if you are in your garage or driveway, place a rag underneath to catch the extra oil.
Step 9. Lubricate the New Oil Filter
Put some fresh clean oil on a rag or your finger and lightly coat the rubber mating surface of the Fram PH6017A or Genuine Honda 15410-MFJ-D01 oil filter. Or put the old and new filters back to back to get an even film of oil on the seal of the new filter.
Step 10. Install the Oil Filter
Position the new oil filter over the filter port and screw it on by spinning it clockwise.Tighten it until the gasket contacts the oil filter mating surface, then tighten the oil filter another 1/2 to 7/8 turns.
Step 11. Add Oil
Step 11. Replace the Dipstick
Put the dipstick back into the oil fill port and tighten it up.
That completes the oil change procedure on a Simplicity Broadmoor Lawn Mower.
