How To Lubricate John Deere X300

John Deere X300 Maintenance

Cordless Grease Gun and John Deere Multi-Purpose SD Polyurea Grease If you own any type of lawn mower then there’s a minimum amount of maintenance that needs to be done in order to keep your mower running well. John Deere Mowers are very easy to maintain when you follow the recommendations in the Owner’s Manual. In a previous post I covered typical John Deere X300 yearly maintenance. One of the really important maintenance projects that I covered was lubricating all the grease fittings. Grease fittings are located on the cutting spindles, front axle spindles, front axle pivot and the deck lift lever. Using a grease gun and lubricating the grease fittings is an easy DIY project for anyone.

Use Recommended Lubricating Grease

John Deere recommends:

  • John Deere Multi-Purpose SD Polyurea Grease
  • John Deere Multi-Purpose HD Lithium Complex Grease
  • If not using any of the preferred greases, be sure to use a general all-purpose grease with an NLGI grade No.2 rating.

I recommend you use a grease gun like the one shown above. I recommend you buy the Lincoln Lubrication 1242 12 Volt DC Cordless Rechargeable Grease Gun with Case and Charger.

My John Deere X300 has a 42 inch cutting deck on it. The 42 inch deck has two cutting spindles that need to be lubricated. The spindle on the left side of the deck has a belt guard on it that needs to be removed in order to reach the grease fitting.

To remove the spindle guard you’ll need to remove two bolts located on either side of the guard. In the photo you can see thatX300 cutting spindle grease fitting. I’m using a socket wrench to remove the bolts. Once you remove the guard it’s a good time to remove any grass and debris that’s built up under the guard.

The grease fittings are located on the back side of the spindle. Attach a grease gun to the fitting and pump one or two pumps of grease into the fitting. When the spindle is full of grease you’ll see a small amount of grease squirt out around the fitting.

The next parts that needs to be lubricated are the front axle spindles. The axle spindles are very easy to located, they are located on the rear side of the left and right front axle spindles as shown in the photo. Again you’ll want to use one or two pumps from the grease gun until you see a small amount of grease squirt out of the fitting.

You’ll also need to lubricate the front axle pivot. The front axle pivot is located in the center of the front axle assembly on the bottom as shown in the photo. This grease fitting is hard to see unless you get on your back and look up under the front end of the mower.

Lubricating Deck Lift Pedal

Proper Maintenance Is Essential

Maintaining your lawn mower according to the manufacturers recommendations is essential to performance and longevity. I’ve been changing the oil, filters and lubricating my mower as recommended by John Deere. I have no doubt that it will continue to perform like the day I bought it.

    I have my JD deck so I can easily get to the fittings but they fitting will not take grease. The fittings themselves done have a hex so how do you get them out? Have to remove the whole pulley and blade to get them out to where it may be possible to get a vise grip on the grease fitting. Are they screw in or factory pressed in?

    Thanks! You have really helped me.

    I have a John Deere 2016 Model X300. In their great engineering, they put grease fittings on the mower spindles, on the top of the retaining nut, but the fittings point straight up and there is no way possible to get a grease gun positioned so that it will grease, due to the frame of the mower being in the way. Why in the world they did not put offset 90 degree grease fittings on the spindles, or ever an offset 45 degree fitting would be ok. I’ve tried to change the fittings and the size of the threads is an oddball size, with a 7 millimeter fitting being too small and and 8 MM is too large. I had to tap the threads to an 8 mm size and install 90 degree fittings on both mover spindles. I wonder sometimes where common sense is when it comes to engineering…Thanks!

    Thanks Todd,
    Great description of how-to!
    Grew up without a father so all of these projects are lookups online.
    I appreciate you taking the time to post!

  6. Dick says:

    There are 90 degree fittings for grease guns.

  7. Brian says:

    You da man! Thanks for taking to to write this!

    Thanks, Todd! Spot on. Just got done greasing all of the grease fittings on my X354 for the first time, and you have confirmed that I did the job correctly.

  9. jim price says:

    Don’t sweat it…You can bet that the bearings are sealed and you can fill the void with all the grease you want and it won’t get to the bearing.

    You can unseal it but if you haven’t it’s an exercise in futility.
