Selection Criteria

Throttle cables aren’t universal even though some manufacturers claim otherwise. The part’s compatibility with the lawn mower’s engine is the key factor in determining whether you can use it or not.

Nonetheless, several other factors can help you decide if a particular throttle cable is a good fit for the lawnmower model you own. I utilized these factors during the selection process to pinpoint the best throttle cables on the market.

So let’s take a look at the search parameters that helped me select the throttle cables I featured in this article.

  • Cable material – All models I included in this article are made of aluminum, which makes them flexible, easy to bend, and sturdy at the same time.
  • Price range – Although these lawn mower parts aren’t expensive, their price still varies from model to model. I used this parameter during the selection process to identify the most affordable and high-end options.

What Does a Throttle Cable Do?

The throttle is one of the most important parts of a lawnmower that is in charge of controlling the speed at which the engine and the blades rotate. Users can adjust the machine’s throttle using the lever that is located on its handles.

The throttle also helps start the engine, and it regulates how all engine parts work or the fuel consumption while you’re using the lawnmower.

Most modern lawnmowers are equipped with throttle cables that adjust the engine and blade speed automatically, while on older models you often have to adjust the speed of these components manually.

In most cases, your lawnmower should operate at the maximum throttle capacity, as it will reduce the amount of stress the engine is taking and lower its operating temperature. Limiting the throttle capacity can also make it more difficult to cut through thick grass or result in uneven cuts.

Signs of a Malfunctioning Lawnmower Throttle Cable

Spotting the first signs of a malfunctioning lawnmower cable is fairly easy since you’re going to need much more time and effort to mow a lawn. Once you start noticing that your lawnmower is no longer operating at its full capacity, you’ll have to figure out if you have to repair or replace the throttle cable.

Here are some of the most common signs that the lawnmower throttle cable isn’t functioning properly.

  • Engine won’t start – A broken throttle cable is often the reason why a lawn mower’s engine won’t start. Checking if this part is in good condition is one of the first things you need to do if you can’t start the engine.
  • Pushing the mower requires more effort – Throttle cable might lose its elasticity over time, and if this happens, pushing the mower over a lawn will become more difficult.
  • Lowered grass cutting capability – Mower’s blades can’t rotate at maximum speed if the throttle cable is damaged. Hence, you won’t be able to get a clean and even cut.
  • Increased fuel consumption – The engine will have to work harder to maintain a constant blade speed if the throttle is faulty, which results in increased fuel consumption.

Replacing a Lawnmower Throttle Cable

Installing a new throttle cable is your only option if you’ve determined that the part is broken. However, it isn’t necessary to service a lawnmower since you can replace this part on your own. You just need a screwdriver and a pair of pliers to replace an old throttle cable.

Here’s what you need to do:

Step 1 – The lawn mower’s throttle cable should be located near the machine’s carburetor’s intake valve, so you should just remove its casing with pliers. Unfasten the screws that attach the faulty cable to the throttle arm and pull the cable out. Don’t attempt to perform any of these actions while the lawnmower is switched on.

Step 2 – Find the wire base at the back of the lawnmower, and proceed to insert the cable through the wire base and throttle arm. Fasten the cable to the throttle handle and measure how long the cable should be before fastening it to other parts of the throttle system.

The cable should be long enough to allow you to fold the handles, so you should avoid over-tightening it before testing its tension.

Step 3 – Let the lawnmower idle to see if you need to loosen the cable. Take the lawnmower for a test run to determine if it is functioning properly.

How to Fix a Stuck Lawn Mower Throttle Cable

Dirt and dust accumulation can sometimes cause the throttle cable to get stuck. As a result, you will have difficulties steering the lawnmower or adjusting its throttle. To flush the dirt and dust from the throttle, you’re going to need a penetrating oil like the WD-40 or JB-80.

You must detach the cable from the engine and the handles, then pour the penetrating oil through a funnel and collect it on the other side with a pan. Use a pair of pliers to check if the cable is moving normally before reassembling the lawnmower.

Take your lawnmower for a test run to check if you can steer it or control its throttle normally. Read our 12-050-01 vs. 52-050-02 oil filter comparison to find out which option is better for your lawnmower.

The Most Important Factors to Consider While Choosing a New Lawnmower Throttle Cable

Before you can start searching for a replacement for the lawnmower’s original throttle cable, you must first check the part’s number. Most manufacturers include this information in the manual, so you should go through the manual to learn more about the model’s throttle cable and suitable replacements for it.

This information will enable you to pinpoint the throttle cable models that may be a good solution for your lawnmower. Let’s take a look at more factors that can help you choose the right throttle cable for your grass cutter.

Cable’s Compatibility

You should go through the throttle cable’s specifications and check if it is compatible with the mower model you own. This is especially important if the throttle cable is compatible with more than one lawnmower.

Manufacturers of these parts usually offer full lists of compatible models, so acquiring this information shouldn’t take too much time. Keep in mind that throttle cables that are advertised as universal don’t fit on all lawnmowers, and you have to check if you can install them on your mower.

OEM vs Aftermarket Parts

Most lawnmower brands recommend OEM parts for their products, so the easiest way to find a replacement for this part is to get the throttle cable approved by the manufacturer.

Parts recommended by the manufacturer can sometimes be hard to find, and they’re usually more expensive than aftermarket throttle cables. Aftermarket parts are also more versatile, as they’re often compatible with multiple lawnmower models.

However, the quality of aftermarket throttle cables isn’t always as good as the quality of OEM parts.

Brand’s Reliability

Opting for a throttle cable that is produced by an unknown brand will make it difficult to check the experiences other users had with that part. That’s why you should get the replacement part that is produced by a reputable brand.

In addition, most of the industry-leading lawn mower brands also produce throttle cables, and you should at least consider buying the replacement parts made specifically for your lawnmower model.

Throttle Cable’s Durability

A throttle cable needs to be flexible and sturdy enough to withstand daily wear and tear. That’s why most throttle cables are made of aluminum, a material that bends easily and responds well to high tension.

These cables stretch over time even if you’re always using your lawnmower on full throttle. Hence, this part doesn’t last longer than a few years.

Replacement Costs

A new throttle cable costs between $10 and $30, so you won’t have to spend a lot of money to repair your lawnmower. The installation process is relatively simple and you only need a pair of pliers, wire cutters, and a screwdriver to complete it successfully.

You’ll have to spend approximately $100 to have this part repaired or replaced by a licensed professional.

The Advantages of Lawnmower Throttle Cables

  • Restored Engine Efficiency

Installing a new throttle cable on a lawnmower will restore the machine’s efficiency to its normal level. It will also reduce the mower’s fuel consumption and prevent the engine from overheating.

  • Improved Cutting Capacity

Throttle cables regulate the speed at which the mower’s blades operate. Once this part becomes faulty, the maximum speed at which blades can rotate decreases, resulting in unevenly cut grass.

  • Easy Replacement

You don’t need to be an experienced mechanic to install a new throttle cable because you just need a basic set of tools to remove an old cable from the lawn mower’s throttle system and attach a new one.

The Disadvantages of Lawnmower Throttle Cables

  • Diagnosing problems with throttle cables can be difficult

Figuring out the reason why your lawnmower isn’t functioning at the top of its capacities isn’t always simple. A throttle cable is just one of the components that can lower the engine’s power output or the blade speed.

That’s why it is advisable to consult a professional while trying to determine why your lawnmower isn’t working properly.
