Problems With John Deere X758 And How To Fix Them

Lawnmowers have always been a good investment for homeowners. But back in the day, with riding mowers costing tens of thousands of dollars, homeowners would mostly go with manual machines.

Now manual mowers are great if you have a small estate but mowing a medium or large lawn with them can be pretty exhausting. Then comes John Deere with their wide selection of riding mowers at all price ranges, making it practical for even homeowners to get a riding mower of their own.

And these days, a John Deere lawnmower is all you need to keep your lawn fresh and tidy. The X758 by them is part of their X700 series and is actually a pretty expensive riding mower.

But the performance it delivers, especially for larger lawns, makes it a valid pickup for just about anyone under the right circumstances. It’s a joy to use and makes your entire job extremely relaxing.

But despite its superior performance, it’s not free of all the typical problems that crop up in a lawnmower due to poor maintenance. If you don’t take care of it, make no mistake, it will start showing a lot of problems in terms of performance and cutting quality.

In this article, I will talk about the problems that you may face in your John Deere X758 and help you understand what you can do to fix them. So, let’s get started.

Common Issues With The John Deere X758 And How To Fix Them

The John Deere X758 is an extremely capable lawnmower that can deliver top-notch performance. That being said, with poor maintenance and reckless use, it can fall victim to a host of issues, such as faulty starters or engine malfunction. If that happens to your mower, you have no one to blame but yourself.

Thankfully, fixing up these maintenance issues is pretty easy as long as you know what you are doing. In this section, I will talk about the common pitfalls with the John Deere X758 and give you some troubleshooting tips to resolve them.

1. Engine Refuses To Start

Trouble starting the engine is pretty common in most lawnmowers, and the John Deere X758 is no exception. If the engine in your lawnmower is not starting, then the most likely culprit here is the fuel system. You need to check the filters and the condition of the fuel to determine what’s causing the issue.

Start with a quick inspection of the fuel and air filters. If the filters are blocked, this would explain why the engine is not getting enough power to boot up. Removing the blockages or replacing the filter should let the engine start back up.

If the filters seem fine, then there’s a chance that the condition of the fuel is the problem. Old, stale fuel can often cause engine issues and can prevent you from using your lawnmower. So, check the fuel condition and replace it if it is stale.

One of the downsides of the John Deere X758 is that it has a low-capacity fuel tank that can only hold up to a quarter gallon of fuel. This amount is only good for around 5 to 6 hours of use. If your mower is running low on fuel, you need to top it off.

2. Engine Stalls Mid-Use

Another common issue that many people report with their lawnmowers is that the engine stalls mid-operation and doesn’t start back up. This can be an annoying issue as this means you will have to push your lawnmower back to the shed as you won’t be able to finish up your work.

But as frustrating as it is, once you understand the reason behind it, you should be able to fix it quite easily. One of the main reasons behind this problem is the fuel filter. When a fuel filter gets clogged, it can limit the amount of fuel that reaches the engine.

And when you are doing anything that pushes the engine, such as mowing uphill or putting it under load, the engine stalls from lack of additional fuel. You need to inspect the fuel filters, clean them up or replace them, depending on the extent of the damage.

 Of course, another culprit here might be the fuel pump. If the pump is damaged or if there are leaks in the line, you need to repair it. This might be hindering fuel flow which is causing the engine to shut down abruptly.

3. Overheating Engine

An overheating engine in your lawnmower is the last thing you want to put up with. If you notice the engine of your John Deere X758 overheating, you need to address it right away. Allowing it to keep overheating can cause the problem to escalate and eventually lead to engine failure.

Overheating in the engine is usually a sign of low engine oil or damaged cooling fins. The engine oil serves as a lubricant to keep the engine heat at bay. If the oil level is low, that explains why the engine is heating up when you are using the lawnmower. Topping off the engine oil should fix things.

You should also inspect the cooling fins and make sure they are working as intended. If the fins are damaged, you might need to replace them. You should also take this chance to clean up the internal components in your lawnmower. Dirt and debris build up on the inside can also cause overheating issues.

If none of these steps fix the engine overheating problem, you need to inspect the carburetor. A dirty carburetor can also lead to engine heat build-up and cleaning it up should set things right in that case.

4. Electrical Issues

Sometimes you may face some electrical issues in your John Deere X758 lawnmower, such as the battery not charging or the headlights not working. There are fixes for everything, so there’s no reason to get frustrated.

Let’s talk about battery issues first. Battery problems can come up in different ways. You may find that the battery is draining too fast, or the battery simply won’t recharge in your lawnmower.

If the battery is draining faster than usual, then the problem might not be your battery at all but rather the battery charger. I would recommend borrowing another charger from a friend and trying your luck with that. If the battery still doesn’t hold a charge, then you might need to replace the battery.

And if your battery is not recharging at all, then there’s a chance the wirings around the battery terminal came loose. You need to inspect the terminals and reset any loose connections to fix the problems. However, if the battery terminals look corroded, then replacing it might be your only option.

On the other hand, if your problem is with a non-functional lamp, then start with a quick inspection of the light plug. Sometimes it can get disconnected due to vibrations and cause the lights to become unresponsive. If the lamps are outright broken, you need to replace them.
