Engine Trouble (No Start)

Ah, the joys of owning a mower. Nothing quite beats the frustration of trying to get your engine started, only to be met with silence. If this sounds all too familiar, fear not – you’re not alone.

But before you start tearing your hair out, let’s take a closer look at some common culprits for engine failure.

First up, electric issues.

Yep, that’s right, your trusty mower needs a fully functioning battery and charging system to get up and running.

So, if your engine is giving you grief, make sure you’re not dealing with a dead battery or a faulty ignition switch. And while we’re on the subject, have you checked those safety switches lately? A little TLC in this department can go a long way.

Assuming your electrical system is all good,

It’s time to turn your attention to air and fuel flow. Is your fuel tank looking a little parched? Make sure you’re using the right type of fuel and that you’re not running on empty.

If it’s been a while since you last filled up, you might be dealing with some sticky, stale fuel that’s clogging up your filters and carburetor. Not exactly a gourmet feast for your mower, if you catch our drift.

So, if you’re dealing with clogged filters or a carburetor that’s seen better days, it’s time to bust out the cleaning supplies. A little elbow grease and a fresh oil change can work wonders for your mower’s health.

Vibration in Mower

Oh, the frustration when your beloved John Deere mower starts to vibrate like a blender! Don’t panic, I’ve been there too. Excessive vibration can be caused by various factors, so it’s important to do a thorough check.

Firstly, check if there’s any foreign material like long weeds or tiny pebbles wrapped around your blade shaft or deck.

Don’t underestimate the power of a small pebble! It can make your mower dance like nobody’s watching.

Engine bolts also play a crucial role in reducing vibration when your mower is in action. Missing or loose bolts can be the culprits of your mower’s excessive vibration.

So, tighten and replace any missing bolts to prevent further damage.

Moreover, damaged blades, worn pulleys or deck belt, and bad spindle bearings can also cause your mower to vibrate uncontrollably. It’s important to inspect and replace any defective components to keep your mower running smoothly.

Uneven Cuts with Mower

Ah, the joys of mowing the lawn. Nothing beats the smell of freshly cut grass…unless, of course, your John Deere Mower is leaving you with uneven, gnarly-looking patches. Not exactly the picturesque lawn you had in mind, right? 

First things first,

Let’s check those tires. Uneven tire pressure can lead to uneven cutting, so make sure each tire is evenly inflated.

Now, onto the blades. Are they looking a little worse for wear? Worn or bent blades can cause some serious mowing mayhem, so if that’s the case, it’s time for a blade change.

But wait, there’s more!

A clogged or unlevelled mower deck can also be a culprit for bad cuts. So, give that deck a good cleaning and make sure it’s adjusted to the proper height. 

And finally, let’s talk speed. Ground speed, that is. If you’re zooming around your lawn like a bat out of mowing hell, or your engine is puttering along at a snail’s pace, you’re likely to end up with some not-so-great cuts.

Engine Stalls While Mowing

Have you ever been in the middle of a productive mowing sesh, only for your mower to sputter and die after just an hour? Talk about a buzzkill. But fear not, dear reader, for we’ve got some tips to help you diagnose and fix this pesky problem.

Let’s talk fuel.

Stale fuel can be a real mood killer for your mower, so make sure you’re changing your oil regularly (once a month is a good rule of thumb).

You can also add a fuel stabilizer to help keep things clean and running smoothly. And while you’re at it, give your air and fuel filters a once-over. Dirty or clogged filters can really put a damper on your mowing game.

If you’ve covered all your fuel-related bases and you’re still having issues,

It’s time to turn your attention to the spark plug. A fouled spark plug can be a major culprit for engine stalling. So, give that little guy a good cleaning (or replace it altogether), and make sure all your spark plug wires are securely attached and properly gapped.

And finally, if you’ve tried all of the above and you’re still at a loss, it might be time to break out the carburetor cleaner. Give all the components a good scrub and see if that doesn’t do the trick.

Engine emitting Smoke 

Ah, the sweet smell of freshly cut grass…or is that smoke coming from your John Deere Mower? White or black smoke billowing from your machine can be a cause for concern, 

If you’re seeing white smoke,

It’s likely due to excessive oil in the crankcase. Think of it like an overzealous oil party, but unfortunately, it’s not good for your mower’s health.

Drain that extra oil until it’s at the recommended level. But hold on, don’t get too eager with the draining – if the oil level is too low, you’ll end up with some serious engine damage. So, be sure to keep it at the right level and contact an expert if you suspect any damage.

Now, let’s talk about black smoke.

No, your mower isn’t running for office, but it might be running a little too rich. A fuel and air mixture that’s too rich can cause incomplete combustion, leading to black smoke.

So, check that fuel and air ratio and make sure it’s on point. Oh, and while you’re at it, give the air filter a once-over – a clogged filter can also cause black smoke. Clean or replace it as needed.

Remember, keeping your mower running smoothly is key to a healthy lawn (and a happy you). 

Steering Problem 

Are you experiencing some wonky steering with your John Deere mower?

Don’t worry, it’s a common issue among all mowers.

Let’s start by checking the tire pressure – uneven pressure can cause your mower to pull to one side like a stubborn mule. And if your dampers are bad, they’ll do the same.

No worries, though, just replace those bad boys with some new ones. And while you’re at it, adjust the speed adjustment bolts and change the rotation speed of the tire if one tire is moving faster than the other – we don’t want any wheelie mishaps, do we?

Last but not least,

Check for any worn or damaged steering components. If you find any damaged bushings, washers or gears, it’s time to give them the old heave-ho and replace them with shiny new ones. Your mower will be steering like a champ in no time!
