Here’s Why Your Mower Has Headlights

Some push mowers and riding mowers have lights on the front. If you only use them during the day, then you probably won’t ever use them. However, it’s good to know about all of your mower’s functions. Riding lawn mower headlights serve the following purposes:

They Illuminate Your Path

The headlights of the lawnmower serve to illuminate the area in front of you when mowing. In some cases, the weather changes, leaving little daylight left to cut the grass. In central Florida, for example, thunderstorms are experienced several times a week in the afternoons during some seasons and the nights are around 80°F. The headlights come in handy in such weather conditions.

Headlights Promote Safety

Metal, wood, stones, and other debris can cause mishaps when mowing at night or in the dark. The headlights illuminate this ensuring your safety when mowing the lawn. They also make it easy for you to identify any hills and bumps that might be in your yard.

Riding mowers are one of the eight ways that you can fight particularly large weeds. Safety is at the front of your concerns, but a malfunctioning headlight can be frustrating. Read on for repair tips.

How to Replace a Lawn Mower’s Headlight

Problems with the socket, bulb, switch, and harness are the reasons why the headlights in your lawnmower might not be working. To replace the headlights, make sure you refer to more specific instructions in the manual on the malfunctioning lights. It may be as a result of a faulty switch user manual. E Replacement Parts is loaded with simple tutorials to repair your headlights. The following are general steps on how to repair yours.

Change the Bulbs

1. Turn the ignition to the off position.
2. Lift the hood of your riding mower and rotate the headlight socket to release.
3. Rotate the old bulb and pull to remove it.
4. Install the new headlight by putting it into the socket and rotate to fasten it.
5. Realign the socket in the headlight housing and rotate it to lock it into place.
6. Examine your new bulbs to determine if they are working. If not, then the problem might be in some other location. If they do work, then the old one has burned out or is defective. After the repair, lower the hood.

Examine the Switches

The function of the switch is to control the power that goes to the bulbs. The switch might be faulty if replacing the bulb with a new one fails. To test this, hook your voltmeter and turn it on. Look for 12 volts, and if you fail to see them attach the positive end of the voltmeter to the other positive terminal in the switch and the negative one to the corresponding opposite end. 

If the voltmeter reads 12 volts, it means power is flowing. The implication here is that the switch is defective and the lights fail to work, and you need to do a replacement.

1. Have the ignition in the off position. Detach the key before you get through with the replacement.
2. Lift the hood, reach into the steering housing, and depress the tabs to release the old switch from it.
3. Note the orientation of the switch and the wires, then disconnect them.
4. Install the new headlights switch by connecting the wires to the appropriate terminals and snapping the switch into the housing.
5. Realign the new switch, and test the lights. Lower the hood after completing the repair.

Adjust the Wire Harness

The wiring harness is responsible for transmitting power from the battery to the switch and eventually to the bulb. The proper functioning of the headlights fails if the harness is faulty or damaged. Inspecting the harness involves attaching your voltmeter to look for 12 volts.

Perform this procedure with all the connectors, and look for a voltage drop. If you sight a voltage drop, examine the plug or socket for any signs of damage. Look out for loose wire connections at the connectors and if they look good, inspect the wiring. Examine the cables for cracks, and if you notice minor damage, fix it up by wrapping the wire with electrical tape.

Contrary to popular belief, riding mowers can last quite a long time. Don’t let a simple wire harness be the end of yours!

Check the Sockets

The sockets keep the bulbs in place with a tight connection to facilitate power flow to the bulbs. Signs of a damaged socket include:

• Bent connectors
• Missing or loose connectors

 To replace a socket:

1. Lift the hood to access the socket.
2. To work on the socket, turn it clockwise and remove the wires.
3. Proceed to make the new connection by stripping off a bit of the harness.
4. Slip the heat shrink over the wires and install the new socket. Join the wires together by twisting and soldering them together. Use proper male and female spade connectors to crimp them on. To get a tight seal that will keep the moisture out, slip the heat shrink over the connector and use a small torch or a lighter to shrink it.
5. Connect the bulb and test if it works

How to Mow a Lawn in the Dark

Most people know that headlights are perfect for night time mowing. Let’s run through the steps to turn on the lights if you’re unsure where they are or how to activate them.

Use Mower Headlights

The headlights illuminate the path at night. Turn the headlights on only when the engine is running to avoid draining the battery. To turn on the headlights, follow the next steps:

1. Take a seat, and flip the ignition switch on your right to start the mower.
2. While still seated in the mowers seat, locate the headlight switch by looking down and to your right. It’s next to the charge light of the battery on most riding mowers.
3. Push the headlight switch with your finger to turn the headlights on.
4. Remember to turn the headlights off once you have finished mowing. Push the headlight switch again to turn it off while the mower is still running.

Wear a Headlamp

You can fix a headlamp over your head when mowing at night to help boost your vision in the dark. Headlamps are ineffective when dealing with a large lawn as they lack enough bright light. To avoid mishaps, get headlights fixed on your mower. Follow these tips by Pro Tool Reviews for DIY headlights.

Wait for Streetlights

If you live in an area with streetlights next to your lawn, you can take advantage of it when mowing at night.

Get an Outdoor Lamp

An outdoor lamp assists in lighting up your lawn at night during mowing. Put the lamp in the area you are mowing to make it visible.

Final Thoughts

Although not all riding lawn mowers come with headlights, you can modify yours to get the best results. There’s no doubt that they’ll come in handy, so why not give it a chance? If your mower already has headlights, then you’re ahead of the curve.

Here’s a rundown of the post:

• Always turn off your lawn mower before working on the headlights.
• You might need to replace the O-rings or gaskets to prevent water penetration.
• Test your work with a voltmeter to find the source of the problem.
