Changing your tractor's oil doesn't have to be a chore. Here's a guide to help:

Check the specs

Before you begin, here are four specifications you need to consider:

  • The type of fuel your tractor uses will determine the kind of oil you use. Diesel motors run hotter than gasoline ones, so heavier oil is required.
  • Keep an eye on the heaviness of the rated weight of various oil. Using properly weighted oil will make your tractor run more efficiently.
  • You also need to determine the correct size and type of oil filter. Filters come in two types, spin on and cartridge. You'll need to change the filter too, so make sure you have the right one.
  • Lastly, motors may have different capacities, so find out how many quarts or liters of oil your tractor takes so you can purchase the right amount.

Drain the oil

Move the tractor to a flat, stable area. Once the tractor is turned off, locate the oil drain plug, which is usually a large bolt on the bottom of the engine. Before you take out the bolt, place a spill pan under it Make sure to always wear protective gloves.

Once removed, wipe the plug clean and check for a sealer, usually an O-ring or metal crush washer. Replace the sealer before proceeding.

Remove the filter

Grab another pan and then find the filter. How you remove it will depend on the type of filter it is. These will have sealers as well, usually O-rings or gaskets. As with those on the plug, these will need to be replaced along with the filter. Cartridge filters typically come with their own, while ones for spin on filters are sold separately.

Get supplies

Now that you have a better idea of what you need, obtain the supplies to finish the job, including oil, a new filter, new sealers for both the plug and filter and a new plug, if necessary. Also, pickup any extras you may need, such as a funnel, shop towels, degreaser or spares for next time.

Replace the filter

Now it's time to put everything back together again. Essentially, you'll do everything in reverse to put the filter back on, with a few modifications. Make sure to coat any new sealers with fresh oil before installing them. For spin on filters, it's best to start by hand, as to not cross thread. Once you're sure it's on correctly, finish up with a wrench. Also, some engines require that the filter be primed before installation, meaning that fresh oil needs to be put in the filter assembly.

Replace drain plug

As with filters, coat any sealers with fresh oil and tighten the bolt by hand first before using a tool.

Dispose of the old oil

The old oil needs to be recycled, which can usually be done at a service shop. Carefully empty the pan into a container to be recycled. Once you're done, degrease any spills, especially on the tractor, itself, before proceeding.

Pour in new oil

Place the newly emptied and clean pan back under the plug. Then, find the tractor's oil fill, which usually is the oil level dipstick hole or close by. Pour in the oil, making sure to account for the oil you already put into the filter assembly.

Check for leaks

Turn on the tractor, placing it in neutral with the parking brake on. While it idles, check for any oil leaks. The pan from the previous step should catch anything that does. If you don't find any leaks, turn the tractor off, then check the oil levels with the dipstick. Top it off, if needed.
