John Deere X300 Yearly Maintenance
Every spring I perform the recommended yearly maintenance on my John Deere X300 mower. I bought this mower just over three years ago so this is the third spring season after three full summers of mowing with it. I purchased a home maintenance kit which contained the oil, oil filter, fuel filter, air filters and spark plugs all in one convenient kit.
Replace The Air Filter
The first thing I did was to remove the air filters. This mower uses two filters, a foam pre-filter and a paper air filter. The foam pre-filter was very dirty and definitely needed to be at least cleaned if not replaced. The air filter didn’t look too bad but honestly, the cost of filters is so minimal compared to the hefty $2,800 price tag of this mower that I just replaced everything.
The air filter on an X300 is located on the front of the engine in the same location a radiator would be on a car. You push down on two tabs to release the filter housing and it just pops out. I cleaned out the housing, installed the foam pre-filter first followed by the new paper air filter. Then I just snapped the housing back in place as you can see in the photo.
Changing The Oil and Oil Filter
The next thing I did was to change the oil. Changing the oil is really easy on this John Deere. They make these engines very accessible for draining the oil and changing the filter is also really easy. The oil drain plug is actually on the end of a drain tube so when you let the oil drain it’s out away from the engine and frame. I like to slide a piece of used cardboard under the mower to catch any drips. Make sure you dispose of the old oil and filter properly (most towns have disposal locations to bring used oil in to be recycled).
Once you get the oil drained make sure you put the drain plug back in and then remove the old oil filter. Next I installed the new oil filter. Before installing the oil filter make sure you take your finger and apply a thin layer of new oil on the gasket, it will help it seal properly. Install the new oil filter and tighten it with a half turn past after the gasket meets the mounting surface. Next add 1.8 L of new oil (follow the operator’s manual for proper oil type).
Changing The Fuel Filter
The next step was changing the fuel filter. This task was a little harder but not impossible. My only gripe here is the filter is attached to the fuel line rather far inside the housing and I had a hard time removing the lower hose clamp. Other than that replacing the fuel filter is fairly straight forward. The only thing is to be careful with the gasoline that will definitely spill out as you do this.
Changing Spark Plugs
The John Deere X300 has two spark plugs located on the front right and left sides of the engine. You’ll need a 3/4 inch spark plug socket or wrench to remove them. Take the old ones out and replace with the new ones that were supplied with the home maintenance kit.
The only other maintenance task I need to perform is greasing the fittings. The whole process only took me about 45 minutes from start to finish and the kit only costs about $42 which I thought was reasonable.
John Deere Mowers are easy to service when you follow the step-by-step directions in your Owner’s Manual.
