1. Park the lawnmower on a level surface, engage the parking brake, and turn off the engine. Allow it to cool down.
2. Locate the transmission drain and fill plugs. The drain plug is typically located at the bottom of the transmission housing and is marked with the "DR" symbol. The fill plug is usually on the side of the transmission housing and marked with the "FR" symbol.
3. Place an oil drain pan under the transmission drain plug.
4. Use a wrench to loosen and remove the transmission drain plug. Allow all of the old fluid to drain into the pan. Make sure the drain pan is large enough to catch the entire amount of fluid that will be drained, about 12 ounces (355 milliliters).
5. Once the transmission fluid has stopped draining, replace the drain plug. Tighten it snugly to prevent leaks.
6. Remove the transmission fill plug using a wrench.
7. Use a funnel to add new transmission fluid to the transmission until it reaches the fill plug hole. The recommended transmission fluid for the Honda mower HR215 is SAE 10W-30.
8. Replace the fill plug and tighten it securely.
9. Start the lawnmower and let it run for a few minutes to circulate the new transmission fluid.
10. Check the transmission fluid level again after a few minutes of operation and add more fluid if necessary.
That's it! You have now successfully changed the transmission fluid in your Honda mower HR215. It is recommended that you change the transmission fluid every 100 hours of operation or once a year, whichever comes first.
