How To Adjust Speed On A Self Propelled Lawn Mower

The generation should entertain this generation. When I was a kid I mowed the lawn. Now someone else’s kid can mow the lawn – Tom T. Hall 

There is nothing quite as aesthetically appealing, or as beautiful as a well-maintained garden.

The vibrant colors and patterns formed by the flora and fauna of any carefully designed garden are relaxing and provide a perfect platform upon which to practice and perfect our horticultural skills.

And the centerpiece of any good garden, as any budding horticulturalist knows, is the lawn.  That’s why it’s important to make sure that your lawn is always trimmed to perfection.

If you don’t devote the time and effort to your lawn that it requires, it doesn’t matter what the rest of your yard looks like, all that anyone is ever going to notice is how overgrown and unkept your grass is.  

Mowing the lawn is a never-ending task that almost all of us find ourselves becoming hopelessly caught up in from our teenage years onward.

Having mowed the neighborhood lawns for a few extra dollars during high school and college, before we know it, we’re faced with mowing and maintaining our own lawns.

It’s the cradle to the grave chore that we’re all familiar with, and the tool that we all grow to know and respect that we spend a lifetime mastering our grass cutting skills with is the lawnmower.

The Self-Propelled Lawn Mower

Most of us get our initial taste of a motor-driven vehicle when we step behind the controls of a self-propelled lawn mower for the first time.

They may not be the gas-guzzling, muscle cars that we dream about driving when we’re teenagers, but they do provide an introductory lesson to the basics of the internal combustion engine, and it’s a lesson that few of us ever forget. 

Truthfully though, we don’t really control self-propelled lawn mowers, We just stand behind them, hold on tight, and guide them to where we need them to go.

The engine does all the hard work on a self-propelled mower, and for the most part, we’re just along for the ride and the time it takes us to mow our lawns, is governed by the speed at which the mower, for want of a better word, mows.

But what if there was a way to make the mower go faster? 

Increasing The Speed Of A Self-Propelled Lawn Mower

Self-propelled lawn mowers are driven by internal combustion engines, and as any devoted car enthusiast will happily tell you, any engine can be made to go faster. 

The easiest way to increase the speed of any engine is by applying more pressure to the gas pedal, or in the case of a self-propelled mower, by increasing the pressure that you apply to the throttle lever on the handlebar. 

The more pressure you apply the throttle lever of the mower, the faster its engine will go, and the faster its engine goes, the faster the mower goes. It’s an easy solution to the problem, but it isn’t the only answer.

There are other ways to make your mower go even faster.

Cheating With The Throttle 

Throttle position is everything. On most mowers, you can actually adjust the position of the throttle lever so that you’ll have more “play” (or more distance) between it and the handlebar.

And the more you can pull the throttle level back toward the handlebar, the more power you’ll be able to generate in the engine, and the more power the engine can generate, the faster the mower will go. 

And the good news is, it’s also incredibly easy to do. Just take a screwdriver, loosen the screw on the throttle housing and let the lever pop forward a little.

When it’s found its new position, simply tighten the screw on the throttle housing again and you’ll have more play in the distance that the throttle has to travel, which means that you’ll now be able to generate more speed from the engine of your mower just by pulling back on the throttle.

More Clean, More Speed

The thing with lawn mowers is that they’re always dirty. The grass they cut gets everywhere, and that everywhere includes the engine. 

And an engine that gets clogged up with dirt, grass trimmings, and all of the other garden detritus that your mower will invariably churn up when it’s trending to your lawn, can, and will, suffer, and its performance will decline. 

The dirtier an engine is, the worse it will perform. 

Like every other internal combustion engine, your mower’s motor relies on being able to ignite a combination of oxygen and fuel to create the combustion reaction that provides the power, through the expulsion of waste gasses from that reaction, that the motor needs to work.

If the motor can’t pull in the air that it needs to combine with fuel, or it’s capacity to do so is reduced, it won’t be able to generate the same amount of waste gases that it used to, which reduces the power of the engine and the speed it is capable of driving your mower at.

The simple solution? Clean the engine. Turn your mower off, turn it over and thoroughly clean the engine by removing all of the visible debris, and checking the places that aren’t so visible with your fingers to make sure that they’re also clear.

Remember to make sure that your mower is fully drained of fuel and that there’s no way that the engine can be switched on while you’re doing this, or there’s a good chance that you’ll end up with fewer fingers than you started with. 

Increase The Octane

The fuel that you use for your lawn mower may also be having a detrimental effect on the speed of its motor.

Low grade and inferior quality fuel can actually leave blockages in the fuel lines of your mower and reduce the amount of fuel that makes it to the motor, which will have a detrimental effect on its speed and performance.

As with car motors, the better quality fuel you use for your lawn mower, the better its performance will be.

If you don’t know how to find higher quality fuel, ask an assistant at your local mower or garden center and they’ll be more than happy to help you find the right fuel for your mower. One that will optimize and improve its performance. 

In The End…

Adjusting and improving the speed, and thus the performance, of your self propelled lawn mower isn’t complex and it isn’t complicated.

It’s straightforward, simple, and providing you follow our easy guide, can be done from the comfort of your own garage.

And you’ll be surprised at how effective it can, and will be, and how much better your lawn will look in record time.

It’s time to put the pedal to the metal and start mowing the right way.
