How Do You Change the Oil in a John Deere 314 Hydrostatic Transmission

The John Deere 314 Hydrostatic lawn mower is a riding tractor featuring a Kohler engine that heavily relies on clean oil for proper operation. You do not need to take your John Deere 314 riding lawn mower into a shop to have its oil changed. You can drain and replace old oil within your machine's reservoir even if you have no experience with changing motor oil.

Turn off your John Deere 314 lawn mower and open the front hood that conceals the engine.

Check the right side of the engine for the spark plug, where the black ignition wire connects. Pull the ignition wire out of the rear of the spark plug before proceeding, for your safety.

Find the oil drain plug on the bottom rear of the mower, near the wheels. Place a pan under the drain plug and unscrew it to release all the old oil into the pan. Set the drain plug back into place.

Remove the cap and dipstick from the oil reservoir. Fill the tank with SAE 30-quality motor oil. Check the oil level using the dipstick and ensure the level of oil within the oil reservoir goes up to the "FULL" line on the dipstick, but no higher.

Put the oil reservoir's dipstick and cap back into place.

Insert the ignition wire into the rear of the spark plug once more. Close the engine's hood.

Change Oil In A John Deere Lawmower

Regularly changing the oil in your John Deere lawn mower is critical to the life of the engine. The project mower discussed here is a John Deere 100 Series riding lawn tractor, but the process is similar for other models as well. Turn on the mower and let it run for 10 minutes to warm up the engine oil. Raise the hood and locate the oil drain valve. Place a drain pan beneath valve. Turn the drain cap counterclockwise with your hand to remove it. Pull the oil dipstick out of its housing by hand. Add only the type and amount of oil specified in your owner's manual; never overfill. Check the dipstick; the oil level on the dipstick should be no higher than the "Full" mark. Add additional oil if necessary until the level reaches or nears the "Full" mark. Make sure that it fits snugly.

Warning

Unplug the ignition wire from the spark plug before changing the oil. Do not overfill the reservoir. Oil should never go past the "FULL" mark on the dipstick.
