Lawn Mower That Consumes Too Much Gas

Lawn Mower Won’t Start. How to fix it in minutes, for free.
  • Save

Lawnmowers are not supposed to consume gas like a thirsty runner who just ran a full marathon without having a bottle of water. If yours does, a clogged air filter is typically your number one suspect.

This causes your mowers engine to work overtime, forcing it to consume more gas to perform its normal capacity. To fix this, just clean your air filter thoroughly or replace it if its over a year old already.

How To Hire A Lawn Mower Technician

  • Read customer reviews. Reading customers testimonials will help you get an idea of the technicians quality of work, communication, attention to detail, punctuality and reputation.
  • Get free estimates. Talk with your lawn mower repair pro about total repair costs and compare that against the original cost of the machine. In certain cases, it may be more cost effective to donate the old mower for parts and invest the repair money you budgeted in a new mower entirely.
  • Ask about a contract. Some lawn mower repair services offer a workmanship guarantee that outlines what type of lawn mower repair services will be provided, which new parts will be included and the total cost for the parts and labor.
  • Ask about discounts. Some motorized lawn equipment maintenance facilities will meet or beat competing companies prices, and some offer military and senior discounts so make sure to ask.

Signs You Need To Buy A New Lawn Mower

Is your old lawn mower struggling? If its not doing the trick and your lawn is suffering, it may be time to invest in a new lawnmower. Most mowers will last around 10 years, but that may vary based on how often you use it, the climate you live in, and the size of your lawn. If you notice any of these problems with your mower, it may be time to look into purchasing a new one.

Change Lawn Mower Oil

To ensure it performs up to its maximum capacity, make sure you change lawn mower oil at regular intervals. Old oil that is black or contains debris should be drained and replaced. This will improve performance, reduce costly repairs and extend engine life of gas lawn mowers. A push mower has an oil capacity of 15 to 18 ounces. It should be changed either every 50 hours or annually, whichever comes first. A riding mower has an oil capacity of 48 to 64 ounces. It should be changed either every 100 hours or annually, whichever comes first.

  • Before changing the oil in the lawn mower, disconnect the spark plug.
  • Remove the drain plug underneath the mower and allow it to drain into an oil-safe container.
  • If the mower does not have a drain plug, use an oil extractor kit to remove oil from the compartment.
  • Add new small engine oil to the compartment up to the dipstick fill line. Oil formulated for small engines will keep your mower running at its best.
  • Be sure to recycle the old oil properly.

Allow The Topsoil And Seed To Settle

Mower Slows Or Stops Mid

If your mower stops in mid-cut all of a sudden, it may have too much grass built up on the underside of the deck. When this happens, the drag on the blade increases, and the motor attempts to compensate for it. Other signs include slowing of the blades with increased motor noise before shutting off. This will cause the mower to pop the breaker. Clean out your deck , and reset the breaker.

Another common cause here is that vibrations from running the mower have caused connections to come loose. Unplug your mower and check all other connections. For some, it may be a good idea to secure them better with electrical tape.

Lawn Mower Engine Hard To Start

Petrol mowers have several reasons why they wont start, with a common one being the spark plug. If the spark plug is not firing, then there is no way to ignite the fuel to fire up the engine. Remove the spark plug and give it a clean to remove any built-up carbon and check the gap is set correctly. If it has not been replaced recently, replace it with the recommended spark plug for your mower.

Next, remove and replace your fuel filter in case it is blocked. While your lawn mower may have a full tank of fuel, it could have been left too long or is not the correct type to use with your mower engine. Empty the fuel from the tank and check the intake system, also check the air filter. You should also top up your oil level before starting it up.

Check that the choke plate closes completely when you engage the choke. If the choke plate does not close completely, then adjust it so it does. If the choke plate is already completely closed, then check that youre getting spark to your spark plug. If the spark is working as expected, then check the compression as per your owner manual. If all is well with the compression, check for a sheared flywheel key. If the compression is not within specification, then you will need to inspect the valve settings, cylinder bore and piston rings.

What Type Of Wheels Should I Buy

For most lawnmowers, the wheel size is approximately 8 inches. However, some high-wheeled lawnmowers have wheels that range from 9 inches to 12 inches.

If your lawn area has high hills or rough terrain, then buy a high-wheeled lawnmower. The large wheels will cause less stress to your lawnmower and can travel through uneven surfaces better.

On the other hand, high-wheel lawn mowers are difficult to push. In addition, they require more effort to rotate at 180-degrees. If you have a small lawn, get a mower with 8-inch wheels as they are less expensive and can cover the area.

Flush Clean Gas Through Gas Tank

How to Fix a Surging Lawn Mower

Once everything in your gas tank has made its way out through the fuel line, I would recommend adding a little bit of fresh gas to the tank to help flush out any residue. You dont need to use too much gas, but this can help get any remaining oil out of the tank and fuel line.

Though a little bit of oil residue wont kill your engine, it can make its way into the carburetor and cause it to get gunked up. If the inside of the tank looks pretty clean after youve added and drained some new gas, you can move on.

Frayed Or Broken Cord

If your mower comes with a cord permanently attached and it becomes frayed or broken, you dont necessarily need to go through the trouble of replacing the whole thing. Use wire cutters to remove the damaged section. Strip about an inch off the end to reveal the black, white, and green wires. Get a male plug end and, using the wiring pattern that comes with it, wrap the three wires around the appropriate contacts . Repeat this with the other cut end using a female plug, or simply plug the remaining cord into an extension cord.

There are more extensive repairs that may be necessary, for which youll need new mower parts and possibly professional help.

Should I Roll My Bumpy Lawn

Answer: In most cases, the answer is no. If you have a lawn with some moderate bumps, rolling may be a viable one-time solution. With that said, its a bad idea to roll frequently, as this could damage your grass. In the majority of cases, correction of the uneven areas by filling in with topsoil will be a better solution.

To solve this problem, lay down the mower on a hard surface. Turn off the engine and ensure there is no engagement of spark plug wire.

Help My Lawn Mower Is Blowing White Smoke

Your lawn mower is blowing smoke. What should you do?

The answer can range anywhere from do nothing to do a bunch. If your lawn mower is blowing black smoke, its burning more fuel than it is air.

If the lawn mower is blowing blue or white smoke, it means the mower is burning oil. Dont panic because this could be a simple fix.

Lawn mowers are meant to work at certain angles. Lets say you became carried away and ran over something which jolted your mower at a steeper angle than intended.

At this point, oil couldve leaked. The lawn mower will burn the oil off, and life is good. If you notice the mower only blows smoke briefly, youre probably in the clear.

However, lets say the mower continuously blows smoke. This could be anything from the crankcases breather, a blown head gasket, or an old cylinder or rings.

Check all of these possibilities and again, you may need to call in a professional or someone more experienced to help.

Bagging Discharging Or Mulching Poorly Problems

How To Fix Lawn Mower That Won

Lawnmowers are vulnerable to mulching, bagging, and discharging. These problems occur when the engine is not functioning at full throttle as it should be. Such issues can be addressed by ensuring the engine is working at full throttle. The deck should put up accordingly and need to be at the same level, and the back should be 3/8 higher than the front.

If the problem persists, think of sharpening or replacing the worn-out blades.

Causes Of Spark Plug Failure

Its worth noting that you should also think about the reason behind the spark plugs failure. Why did your mowers spark plug fail in the first place? Was it just because of regular wear and tear and use, or could there have been another reason?

Sometimes these spark plugs can become worn or damaged due to other problems with the mowers engine. If thats the case, and you replace the plug without identifying the root cause of the damage, your new spark plug is likely to suffer the same fate.

Think about possible root causes of the spark plug failure, such as a dirty air filter, a faulty or filthy fuel injector, damage to the distributor case, or some problem with the mixture of fuel and air within the gas mower tank.

Check all of these potential issues to ensure that your mower is in good shape. Just like your car, the mower needs an occasional tune-up, and this is as good a time as any to make that happen.

Why Is My Mower Not Cutting Correctly

A mower not cutting correctly is usually caused by problems with the lawnmower blades. To get the most efficient cut, the blades need to be sharp, however after a long lifespan they can become blunt. When this happens, the blades will tear the grass rather than producing a clean cut, which damages the grass. It is an easy fix all you need to do is sharpen or replace your lawnmower blades.If you opt for the sharpening route, you will need to make sure they are perfectly balanced when they are returned to the lawnmower. The lawnmower blades spin incredibly fast so you need to make sure everything is in perfect condition. If you over-sharpen your blades on one side the blades become unbalanced and unstable. This is not only bad for the lawn, as it will affect the quality of the cut, but it can also cause irreparable damage to the lawnmower itself.
