Like any machine or equipment used for heavy duties, lawnmowers require periodic servicing and repairs to keep them in the best condition for efficient use. Using a faulty lawnmower can affect the quality of your grass and can cause accidents that may result in serious injuries to the operator or innocent bystanders.
Before abandoning your faulty lawnmower or spending money on a lawn mower repair, you should find out if it is a common lawnmower problem that you can solve by yourself at home.
This article will highlight five common problems relating to lawnmower service and repairs that you can solve at home.
With any DIY lawn mower repairs, safety is a priority! If you are working on a petrol mower, be sure to remove the spark plug or at least disconnect the spark plug cable. This will save you from any potentially serious accidents.
1. The Lawn Mower Engine is Difficult to Start
Table of Contents
When it comes to petrol mowers, there are various reasons why they will not start. The spark plug is one of the most prevalent. There is no way to ignite the petrol to start the engine if the spark plug is not sparking. Remove the spark plug and clean it to remove any carbon build-up or other debris. Then, double-check that the gap is adjusted appropriately. If it’s too far gone or hasn’t been changed in a while, replace it with the proper spark plug for your mower.
Next, if your petrol filter is clogged, remove it and replace it. Even though your lawnmower has a full tank of fuel, it may have sat for too long, or it might not be the right type for your mower engine. You may have to siphon the stale fuel from the tank and fill it with fresh fuel. Remove the fuel cap and inspect the intake system, as well as the air filter. Before starting it up, you should also top off the oil.
If you still can’t get it working, it may be time to call a professional. For those of you who are a little more on the advanced side, you can try the next few steps to get the engine started.
When you engage the choke, make sure the choke plate shuts fully. If it doesn’t, make the necessary adjustments. Assuming you’ve checked that your spark plug operates properly, check the compression according to the manual. Check for a sheared flywheel key if the compression is okay. If it isn’t, look at the valve settings, cylinder bore, and piston rings.
We’re focused on petrol mowers here, but a quick discussion on electric mowers is worthwhile. If you have a cordless lawn mower and it won’t start, one obvious candidate is the battery. Give you battery a decent charge and try again. Better yet, try an alternative battery as the battery you were using may no longer be viable. If it still doesn’t start, at least you’ve eliminated one potential source of the problem. See these other potential reasons why an electric mower keeps cutting out.
2. The Lawn Mower Starter Rope is Stuck or Hard To Pull
The engagement of the engine flywheel brake is the most common cause of this problem. Before drawing the rope again, make sure the flywheel brake is pressed on the handle. If the issue remains after checking the flywheel brake, inspect the lawnmower blade.
The blade dragging on the ground or the cuttings attached to the blade might cause the lawnmower rope to become caught or difficult to remove. Place the mower on a firm surface to tackle the problem. Make sure the spark plug wire is not engaged before turning off the engine. Remove any cuttings, mulch or dirt from the bottom side of the blade and undercarriage with care, then return the lawnmower to its original position and pull the starting rope again.
If the problem persists, it is possible that more than one component of the lawnmower is malfunctioning and has to be fixed. Here, you will need to contact the manufacturer or someone with experience in lawnmower servicing to seek professional advice.
Electric mowers are much easier to start, so if this whole starter rope thing has pushed your patience one too many times, then perhaps its time to go electric, or if you have a suitably small lawn, a decent reel mower could be a good option.
3. The Lawn Mower is Slow
The lawnmower slows down significantly due to damage or dislocation of the drive belt. In the motor casing, you will find the drive belt. Check the manual for confirmation if you are unsure about the placement. While the mower is off and the spark plug cable is disconnected, inspect the drive belt. Reattach the drive belt if it is loose. If it is broken, you should get a new one. Drive belts are easy to come by since you can purchase them online from the comfort of your home. You can resolve this lawnmower problem easily by replacing the drive belt.
Another source of the problem may be that your lawn has grown to tall and you are trying to cut back too much lawn in one pass. If this might be the case, try increasing the height of your lawn mower blades and doing a few passes, lowering the height each time. This might be the simple fix you need to get the job done.
Again, we’ll quickly mention electric mowers. For cordless lawnmowers, examine the battery. Batteries that are not working, have weak charge or are at the end of their useful life might be part of the problem. That said, batteries are usually not the cause of lawnmowers slowing down, these are more a source of the mower not starting.
4. The Lawn Mower is Bringing Out Too Much Smoke
When using a petrol mower, this is one of the most typical issues you will face. Most lawn owners feel that the smoke indicates that the engine will explode. But don’t worry, this is a frequent issue that is not life-threatening. Overfilling of the oil chamber is the most common cause of engine smoke. Examine your chamber to see whether this is the case. A leak or a series of leaks in the oil chamber can cause this issue by allowing oil to get to places it shouldn’t be. Not enough engine oil can also cause a similar problem.
If your oil level is fine, the problem can still occur. When travelling through a region that is not level (your next job will be to level your lawn!), the mower may lean to one side, allowing oil to seep into the muffler and causing the engine to smoke. In this instance, turn off the motor and wait for it to cool before inspecting the oil chamber for any leaks by placing a tray beneath the mower and waiting a while for any oil to appear in the tray. The cap may be loose if there are no leaks. Start the mower again after tightening the cap. Replace the cap if the problem persists.
Smoke only indicates a serious problem in rare instances. If the smoke created is white or very light in colour, and the mower is not running continuously, it is advised that you take your mower to a competent repair shop.
5. The Lawn Mower Loses Power While Mowing
When a lawnmower makes a series of splitting noises while in operation, it means the engine is going to shut down.
One of the causes of power loss is a clogged filter. Look through the owner’s manual to determine where the filter is, then remove and clean it. If the filter is too dirty, you should consider changing it. It is quite inexpensive to change a filter.
If the filter is operating properly, compare the height of the grass to the mower’s height cutting settings. Increase the cutting height if you see the grass is too tall and try to take on the job in a few passes, lowering the cutting height each time.
Cleaning the blade might also assist in resolving difficulties with power loss. Read the manufacturer’s handbook and follow the recommendations for cleaning the mower blade but always disconnect the spark plug first.
If the problem persists, replace the spark plug. Most lawnmower owners can get their mowers up and running by cleaning or replacing the spark plug. Spark plugs are reasonably priced and may be purchased online or at any home improvement store.
Another issue you will encounter with a lawnmower is a blunted blade. The mower will not cut the grass adequately if the blade is blunted. The solution in this scenario is to either sharpen the mower blade or replace it with a sharper one, again making sure to unplug the spark plug
Now that you know the common problems you may face with your lawnmower and how to solve them yourself, it is important that before you start the lawnmower repairs, you should look at the owner’s manual. Also, before attempting any lawnmower repair at home, check if the equipment is still under warranty. Many leading manufacturers may offer a free lawnmower service or maintenance periodically, which could save you time and cost you nothing. After all, who doesn’t like free stuff!?
If you’ve managed to fix it, then well done! Pat yourself on the back! It’s honestly not a common trait these days to tackle a problem on your own, and you should be genuinely proud of even trying, let alone succeeding! Prevention is your next goal, so be sure to regularly maintain your mower and make sure to store your mower in an appropriate place.
If you lawn mower really is kaput, then you can consider involving a professional, but this can get costly and you may just run into problems again. It might be time for a new one. So get yourself one of the best petrol mowers available in the UK or, if you have a small to medium sized garden, it might be worth considering an good quality electric mower.
