How to Change Oil in a Garden Tiller

Before you fire up your garden tiller in the spring, it's a good idea to give it an oil change. Double check the owner's manual for a schedule of exactly how often you should change the oil. This is a fairly easy DIY project, and should take about 30 minutes to complete. Here's how to change the oil in a front tine garden tiller.

Tools and Materials Needed:

  • Oil
  • Socket wrench
  • Adjustable wrench
  • Drain pan
  • Funnel

Step 1 - Prepare Garden Tiller

Move the tiller to a flat work space. Take off the depth regulator; it should twist to one side and slide out, but you may have to check the owner's manual for some models. Move the wheels backward into the till position. Take out the bolts on each side that hold the dirt shield in place. Remove the dirt shield.

Step 2 - Pull the Plug

Put your drain pan in place for the oil. Locate the oil plug on the base of the garden tiller. You may have to turn it on its side to find it. Put the tiller back in the upright position before removing the plug with the socket wrench. Let the oil drain out.

Step 3 - Put it Back Together

After the oil stops dripping, put the oil plug back in. Get it fairly tight, so it won't vibrate loose when operating the garden tiller. Replace the dirt shield and put the wheels back in the upright position. Reinstall the depth regulator.

Step 4 - Fill with Oil

Remove the dipstick, and use the funnel to fill the garden tiller with oil. Replace the dipstick, and you're ready to start tilling.
