Fixing John Deere Mower Deck Will Not Lower

  1. Making Sure It Is Installed Properly

Before you try and do any troubleshooting on the machine, the first thing that you should most probably check is whether the mower deck is installed correctly. It is possible that you might have made a slight error while attaching the mower deck.

Start by taking a look at the user manual for the mower deck and see how you are supposed to install it. If you can’t find your manual for some reason, you can easily find it online.

So, be sure to go about checking up on the installation when you’re stuck in these errors. 


Also, make sure that you follow each and every step required in order to install the attachment. Once you have put everything back together, it should start working again.

You also have the option of getting pointers from local experts. There is no point in trying to get through the fix on your own. 

So, if you’re sure that the system is in a level place and the deck is not damaged, you still have a decent shot of fixing the issue. Just check up on the main connections, and the nuts, and try to loosen up the braces to allow room for some movement.

This doesn’t mean that you want the deck to move about the axis. Instead, you need to focus more on making sure that the connection is not too tight.

So, there should be no wiggle room, and the deck should be perfectly level with the ground. That will give you more perspective on the situation. 

It is crucial that you perform all of these fixes on a level patch and make sure that the front and the back end of the system are in optimal condition. That will help you out through these errors, and you will not have to worry as much about the system. 

  1. It Might Be Locked in Position

What most people don’t know is that mower decks usually come with the option of being able to lock in position. Most usually, there is a particular lever that is used to tell the deck to lock itself.

If the lock is engaged, you will be unable to move the deck to either an upward or downward position.

It is also worth mentioning that most John Deere mower decks also have specific positions controlled through the lever. Do make sure that the deck isn’t locked in place.

So, be sure to check up on the lever and make sure that the lock is disengaged.

It is one of the more common issues that gardeners have to deal with, and you should try to educate yourself on the operating sections. That will help you limit a lot of issues, and you will not have to worry about the deck being locked in place.

The main purchase of this feature is to help owners with better stability. When the system is locked up, you will not have to hassle with as many errors.

Managing the system will become fairly simple when you’re aware of the different features offered by this system. 

  1. Check Blades

At this point, you should just start checking the blades for hardware damage. There might be issues with the blade being bent downwards and touching the ground.


If that is the case, the deck won’t lower and you will have to get a replacement.

Many situations can lead to this issue with the blades not being in their proper orientation. So, you will have to be more mindful of the usage. Too many rocks or going through rough patches without lifting the deck will only complicate the situation. 

So, when you’re stuck in these errors and can’t seem to figure out a solution, we suggest that you reach out to the dealer. That way, you will not have to go through as much hassle when it comes to getting a replacement for the blades.

From there, you can just install the new blades and then go about adjusting the deck one more time. Hopefully, you will not have to deal with the same complications again, and fixing the system will come easily to you. 

  1. Check Connections

Next, you have to check up on the linkages again. If you’re sure that the blades are in good shape, the next thing to do is to check the braces as well as the linkages. This is especially true when you’re running into these errors after reinstalling the deck.


So, be sure to sort out those errors by checking up on the linkage. Most of the time, owners make the mistake of overtightening the nuts and pushing the deck firmly against the base.

This increased tension in the unit will only lead to more errors with the unit. 

What you can do in this situation is to bring down the tension a few notches and that will be enough to have you sorted out here. However, if you’re not that lucky, and the issue persists, then you have to check up on the deck itself. 

There is a good chance that the issue is more related to the deck itself and you will not be able to fix these errors by only limiting the situation to the connection or installation. So, be sure to follow along with the pointers here and then reach out to the dealer.

  1. Potential Damage

If you haven’t had any luck in solving the problem so far, then it is highly likely that there might be some sort of internal damage or fault. Whatever the reason may be, you will have to take a good look at the mower deck.

But at this point, it is much better if you decide to call in a professional on the field. Let him have a look at your mower deck. Chances are that there might be some damaged wire or component that needs to be replaced or fixed.

There is no point in spending hours upon hours of your time trying to fix these issues on your own. Instead, you need to get help from the officials and have them sort you out.

Otherwise, you will just be digging yourself a deeper hole, and won’t be able to find a solution. 

The upside here is that John Deere’s official team is pretty solid and will be more than happy to help you get through these errors.

So, when you’re stuck in these errors and can’t seem to find a fix, just reach out to the officials. They will be more than happy to help you sort out this situation. 

The Bottom Line:

Sick with having your John Deere mower deck which will not lower at all? While the issue is mostly caused when the mower deck itself isn’t installed correctly, there could also be some fault that isn’t letting the deck lower itself.

In either case, we highly suggest following the instructions that we have written in the article above.

It will not be that challenging to get the deck working again if you’re somewhat experienced with the basic care requirements. So, be sure to spare some time and check the deck as well as the blades.


If you’re lucky, you will not have to get any replacement components. However, if the linkages or the deck itself is damaged, then you’re out of luck. You will have to spare some time to get a new piece, and managing the system will be fairly challenging. 

Lastly, you can just call it a day and get help from the official dealer. There is simply no point in trying to get through these errors on your own, and you can seek help from the official dealer.

He will not charge you a lot, and you can claim a replacement in no time.
