How To Start Push Mower

Push mowers are a great way to keep your lawn looking neat and tidy. They’re relatively easy to use, but there are a few things you need to know before you get started. In this article, we will provide you with step-by-step instructions on how to start a push mower. We will also discuss some troubleshooting tips in case you run into any problems.

Before you start mowing, it’s important to make sure that your mower is in good working condition. Check the oil level and make sure that the blade is sharp. You should also check the air filter and spark plug to make sure that they are clean. Once you have checked these things, you are ready to start mowing.

To start a push mower, simply pull the starter cord. The mower should start right up. If it doesn’t, you may need to prime the carburetor. To do this, turn the fuel valve to the “on” position and press the primer button several times. Once the carburetor is primed, pull the starter cord again. The mower should now start.

Preparing the Push Mower

Engine Maintenance

To ensure a smooth start, it’s imperative to prepare the push mower’s engine. Firstly, check the oil level using the dipstick. Add oil if necessary, following the manufacturer’s specified type and quantity. Next, inspect the fuel level and refill the tank with fresh unleaded gasoline. Avoid using fuels with an ethanol content exceeding 10%, as it can damage the engine. Additionally, clean the air filter regularly to prevent engine bogging due to poor airflow.

Safety Checks

Prior to starting the mower, ensure your safety and the safety of others by conducting thorough safety checks. Inspect the cutting blade for damage, cracks, or loose bolts, and tighten or replace it if needed. Clear the work area of debris, stones, or other obstacles that could be propelled by the mower. Ensure all handles and controls are functioning correctly and securely attached. Wear appropriate safety gear, including earplugs, safety glasses, and work gloves, to protect yourself from noise, debris, and potential injuries.

Engine Fuel System

The fuel system plays a crucial role in starting the engine. Verify that the spark plug is properly connected and not fouled or damaged. Replace the spark plug if necessary. Also, ensure that the fuel line and carburetor are free from blockages or leaks. A faulty fuel system can prevent the engine from receiving the necessary fuel mixture, resulting in starting difficulties.

Oil Maintenance	Safety Precautions	Fuel System
Check oil level and add if needed	Inspect cutting blade for damage	Verify spark plug and fuel line
Use specified oil type and quantity	Clear work area of obstacles	Replace faulty spark plugs

Fueling and Priming

Before starting a push mower, it is essential to ensure it has adequate fuel and proper priming. Follow these steps to prepare your mower:

Fueling

Locate the fuel tank, typically on the side or top of the mower.
Use a clean fuel container to fill the tank with unleaded gasoline, as recommended by the manufacturer.
Avoid overfilling the tank. Leave a small gap at the top for expansion.
After fueling, wipe up any spills and dispose of the fuel container properly.

Priming

Priming helps draw fuel into the carburetor, making it easier to start the engine. Here’s how to prime a push mower:

Setting the Blade Height

Adjusting the blade height allows you to customize the length of your grass cut. Different grass types and conditions require different blade heights:

Cool-season grasses (e.g., Kentucky bluegrass, fescue): 1.5 – 3 inches
Warm-season grasses (e.g., Bermuda, zoysia): 1 – 2 inches
Spring and fall: Taller blade height (2-3 inches) to encourage deep root growth
Summer: Shorter blade height (1-2 inches) to reduce water loss and heat stress
During droughts: Taller blade height (2.5-3 inches) to conserve moisture

To adjust the blade height:

Locate the blade height adjustment lever: Usually found on the mower’s side or rear.
Choose the desired height setting: Most mowers offer a range of heights from 0.5 to 4 inches.
Move the lever to the appropriate position: The height markings on the lever should correspond with the actual blade height.
Secure the lever: Some mowers require you to tighten a bolt or lock the lever to keep the setting in place.

Mowers with Primer Bulbs	Mowers without Primer Bulbs
Locate the primer bulb, usually near the carburetor. Repeatedly squeeze and release the bulb until fuel flows into the clear line or you feel resistance.	Tilt the mower back slightly. Hold the spark plug wire away from the spark plug. Pull the recoil starter rope several times to pump fuel into the carburetor. Replace the spark plug wire.

Blade Height for Different Grass Types and Conditions
Cool-season grasses (e.g., Kentucky bluegrass, fescue)	1.5 – 3 inches
Warm-season grasses (e.g., Bermuda, zoysia)	1 – 2 inches
Spring and fall	2-3 inches
Summer	1-2 inches
During droughts	2.5-3 inches

Engaging the Drive System

Once you’ve started the engine, you can engage the drive system to propel the mower forward. This is typically done by pulling back on a lever or depressing a pedal located on the mower’s handlebars.

When you engage the drive system, the mower’s wheels will start to turn, providing power to move the mower forward. The speed at which the mower moves can be controlled by adjusting the throttle lever. To slow down or stop the mower, simply release the drive lever or pedal.

There are two main types of drive systems used on push mowers:

1. Friction Drive: Friction drive mowers use a friction disc or belt to transfer power from the engine to the wheels. This type of drive system is simple and relatively inexpensive, but it can be less efficient than other types of drive systems.

2. Gear Drive: Gear drive mowers use gears to transfer power from the engine to the wheels. This type of drive system is more efficient than friction drive systems, but it can be more expensive.

The type of drive system that is best for you will depend on your needs and budget. If you are looking for a simple and inexpensive mower, a friction drive mower may be a good option. If you want a more efficient mower that can handle tougher terrain, a gear drive mower may be a better choice.

Here is a table summarizing the key differences between friction drive and gear drive systems:

Feature	Friction Drive	Gear Drive
Power transfer	Friction disc or belt	Gears
Efficiency	Less efficient	More efficient
Cost	Less expensive	More expensive

Starting the Engine

### 1. Check the oil level:

Make sure the oil level is between the “Full” and “Add” marks on the dipstick. If it is low, add oil until it reaches the “Full” mark.

### 2. Fill up the gas tank:

Use unleaded gasoline with an octane rating of 87 or higher. Fill the tank until it is about 95% full.

### 3. Locate the spark plug:

The spark plug is usually located on the side of the engine. Remove the spark plug wire from the spark plug.

### 4. Set the choke:

There are two types of chokes: manual and automatic. If your mower has a manual choke, move the lever to the “Choke” position. If it has an automatic choke, it will set itself when you pull the starter cord.

### 5. Pull the starter cord:

Grip the starter cord handle firmly and pull it towards you smoothly and evenly. Do not yank on the cord, as this can damage the engine. Continue pulling until the engine starts. Once the engine starts, release the starter cord.

Troubleshooting Tips	Possible Causes
Engine won’t start	– Empty gas tank – Clogged fuel filter – Faulty spark plug
Engine starts but runs rough	– Dirty carburetor – Worn spark plug – Low compression
Engine runs but won’t move	– Broken drive belt – Slipping clutch – Faulty transmission

Choking

Choking is a process that increases the fuel-to-air ratio in the engine, making it easier to start when cold. Follow these steps to choke your push mower:

Locate the choke lever, typically near the air filter.
Move the lever to the “choke” or “closed” position.
This will restrict airflow and increase fuel flow.

Throttling

Throttling controls the engine’s speed and power output. Adjust the throttle according to the following guidelines:

For starting, move the throttle lever to the “slow” or “idle” position.
As the engine warms up, gradually increase the throttle to achieve the desired speed.

Common Problems and Solutions

A faulty spark plug can prevent the engine from starting. Remove the spark plug and check for any cracks or damage. Replace the spark plug if necessary.

Tighten Loose Connections

Loose connections can prevent electricity from flowing to the engine. Check all electrical connections and tighten any loose bolts or nuts.

Remove Obstacles from Deck

Before starting the mower, make sure there are no obstacles stuck in the deck. This can cause the engine to stall or damage the mower deck.

Engage Safety Features

Most push mowers have a safety feature that prevents the engine from starting unless the operator is in the correct position. Make sure you are standing behind the mower with the safety handle engaged before starting the engine.

Pull Starter Cord

Slowly pull the starter cord until you feel resistance. Then, give the cord a quick, sharp pull to start the engine.

Adjust Choke

If the engine doesn’t start after a few pulls, adjust the choke. The choke helps to start the engine in cold weather by restricting airflow to the carburetor. Once the engine starts, gradually open the choke until it is fully open.

Control Throttle

The throttle controls the speed of the engine. Adjust the throttle to the desired speed for mowing.

Tips for Efficient Mowing

Mow Regularly

Mowing regularly helps to keep your lawn healthy and prevents the grass from getting too long and difficult to cut.

Mow at the Correct Height

The ideal mowing height depends on the type of grass you have. In general, it is best to mow at a height of 2.5 to 3 inches.

Sharpen Your Blade

A sharp blade will cut the grass cleanly and evenly. Sharpen your blade regularly according to the manufacturer’s instructions.

Overlap Your Passes

To ensure an even cut, overlap your passes by about one-third.

Avoid Mowing Wet Grass

Mowing wet grass can damage your lawn and make it more difficult to cut. Wait until the grass is dry before mowing.

Empty the Grass Catcher

Empty the grass catcher frequently to prevent the grass from clogging the deck and reducing the efficiency of the mower.

Clean Your Mower

After each use, clean your mower to remove any grass clippings or debris. This will help to keep your mower running smoothly.

How To Start A Push Mower

Push mowers are essential tools for any homeowner. They’re relatively easy to use, but there are a few things you need to know in order to start them safely and correctly. Here’s a step-by-step guide on how to start a push mower:

Check the oil level. Before you start the mower, check the oil level. The oil should be at the "full" mark on the dipstick. If it’s low, add some oil until it reaches the mark.
