In that location's zip quite as frustrating as a faulty lawnmower. Fortunately, if your riding mower won't start and no clicking comes from the engine, you might not need a replacement simply still.

Beneath, our experts take put together the potential issues with a riding mower that won't start or click and provide troubleshooting tips to assist your riding mower work once again.

How to Set up a Riding Lawn Mower That Won't Start

You should be able to notice out the problem with your tractor or mower yourself. Merely kickoff, ensure you fix the parking brakes.

Then check if the blade is notwithstanding disengaged. Your riding mower won't work otherwise.

Materials You Will Demand

Piece of work gloves
Safety goggles
Multi-meter
Screwdriver
Wire brush

How a Riding Lawn Mower is Powered

Riding mower is powered by a four-cycle engine (intake, pinch, combustion, and frazzle). Some mowers use gasoline as their fuel and a spark plug to combust it. Others are powered past diesel and require no spark plug. In either case, the engine runs the transmission and drive wheels, and rotates the cut blades underneath the automobile.

Similar car car, riding mower utilize a new battery, starter motor, and ignition switch. When you plow the ignition switch to the 'Start' position, 12 volt of direct current travels from the battery through the starter solenoid to the starter motor. This current also flows through a cable to the anti-afterfire solenoid in the engine

When yous release the key to the 'Run' position, this DC of twelve (12) volts is and so redirected. Instead of going to the starter and motor, information technology moves to the alternator and anti-afterfire solenoid but. Together, these parts assistance to charge the battery and start auxiliary ability sources similar headlights and power plugs.

If your high-quality zero plow mowers piece of work fine, you lot would hear a clicking audio between the 'Run' and 'Start' positions. This implies that the starter solenoid is getting power from the battery. On the other hand, when you don't hear a click from the engine, the starter has failed, or its curlicue isn't getting power from the battery.

Although mowers differ from models, they all piece of work on the same principles.

Check and Charge/Replace Dead Battery

Battery troubles are one of the nigh common reasons a mower won't run or click. A corroded bombardment won't start an engine, and neither volition a tuckered battery, when y'all forget to plow off the safety switch.

A service monitor on a mower can assistance you identify when you've got battery troubles. But without one, you can bank check the bombardment using a multi-meter past following these steps:

Turn off the ignition system before accessing the battery.
Set up the multimeter to DC voltage
Use the multi-meter'southward red probe to affect the positive final and the black probe on the negative concluding.

If the multitester reads more than twelve (12) volts, the bombardment is good. Otherwise, information technology is weak, or dead and you lot've plant the problem with your mower.

You can recharge relatively new batteries by:

Accessing the battery, which is unremarkably under the driver's seat.
Connecting the charger clips to the battery terminals.
Plugging the charger to a power outlet. The charger should work on at least 10volts to charge the bombardment. Still, a 12-volt charger is sometimes preferred.
Disconnecting the charger reversing the steps higher up.
Plugging the charger to a power outlet. The charger should work on at least 10volts to charge the battery. Still, a 12-volt charger is sometimes preferred.
Replacing the seat and reconnecting the new battery in your mower correctly.

If a simple recharge doesn't work, you demand to replace the battery pack in the mower. Avoid a spring kickoff mower to prevent damages to the on-board system

Check the Ignition Switch

The trouble with your mower could be with the switches. When y'all start the engine, your ignition switch's contacts complete a circuit. This circuit is from a red to a white wire, which is on the B-final and Southward-terminal, respectively.

Our team suggests to check the switch past measuring the resistance between these terminals.

Pull up the mower's hood to admission the ignition switch.
Remove its cable harness.
Remove the tabs to pull the ignition switch out of its slot.
Turn the cardinal to the first position and set the multi-meter to measure resistance, not voltage.
Connect the black multi-meter probe to the B prong and the other to the South prong. These terminals are along each other's diagonal at the lesser of the switch.
Utilize the key to turn the ignition switch and start the engine. The resistance should brandish on the multi-meter when you lot do this.

The height-rated riding mowers should take good ignition switch measuring 0 ohms. This means its contacts complete the B and S last excursion and tin can send voltage to the solenoid. On the other hand, a damaged ignition switch will measure infinite resistance.

Other common issues yous can experience with a damaged ignition switch include loose wiring and connections, corrosion, or spinning ignition. To fix this problem, check the ignition wiring for corroded, damaged, or loose wires

Inspect the Control Module

A command module is a printed circuit with resistors, relays, and a ground side that receive commands from the safety switches. If the sensors in the motor work correctly, a circuit module volition also output a control to the starter through the solenoid. However, non every mower has one.

Depending on your model, a control module could be anywhere, even under the seat. And if you find that your loftier-quality electric riding mower won't start no clicking comes from the device, or cranking doesn't piece of work, then this module could be faulty.

There are ii ways to bank check the control module yourself:

Jerk exam: Here, wiggle the red and black wires connected to the control module while you first the mower. If everything checks out fine and the wires are continued, visually check the printed circuit for water damage and loose connections. To relieve time, you may accept someone help yous with the wires in a jerk test while you focus on finding the outcome.
Main fuse check: Modules have internal or external fuses, and a diddled fuse cuts out the supply from the bombardment. First, to check the fuse, remove its zip tie and so pull the fuse from its holder. If whatsoever chemical element in the fuse is broken or there'due south a fault in the ground connection, yous should have it replaced. However, if you're unsure, you lot can check for continuity using your multi-meter.

A good fuse should measure near 0 ohms. On the other paw, a blown fuse will measure infinite resistance.

Check Safety Functions

Every mower fifty-fifty the cheapest riding mower you tin detect in the market has in-built safety features. Typically, sensors or switches control these features, and they are routed through the command module. In one case a detector activates a condom office, your mower won't work as usual.

The primary ones to check are the brake pedal switch, bract switch, battery connection, weight sensor (to brand sure a driver is sitting before the mower works).

When you lot jump kickoff the engine, you should press your brake pedal. If the brake pedal doesn't work, then you demand to inspect your brake detector.

Remove the hood and air-duct screws.
Pull off the air duct and have the fuel tank and filter out of the way.
Pull the cablevision harness off the restriction switch, noting the wiring.
Using the multi-meter probes, affect both prongs that connect to the wiring of the brake detector.

If the restriction switch is okay, the multi-meter should display 0 ohms of resistance. Supersede this switch if you read infinite resistance from your multi-meter.

A riding mowers engages when the bract knob is switched off or the transmission isn't gear up to park. To check the bract switch, our experts recommend to practise the post-obit:

Have out the clutch lever mounting screws. The assembly should drib slightly when the screws aren't in place.
Note the prong's wiring and then disconnect the blade switch's cablevision harness.
Using your multi-meter probes, affect both prongs to measure the resistance of the bract switch.

Similar earlier, 0 ohms implies your bract switch is proficient, while infinite resistance means you need to replace it.

Motion detectors, switches, and sensors have in-congenital override functions. These functions are by and large used for tests, and simply disconnecting a detector can crusade an override. If you doubtable your sensors are on an override, our team suggests to reconnect them before starting the device.

Replace Faulty Solenoid

Follow these steps to change a faulty solenoid:

First, raise the seat to get to the battery. Then, disconnect the battery terminals, starting with the negative (colored black) and then the carmine
Remove the battery from its slot. While at it, check for leaks or corrosion at the bottom and sides. Make clean corrosion off the cablevision leads with a wire brush if they are still there afterward dusting.
Disconnect the cable harness that'southward connected to the seat'due south detector.
Pull off the bombardment box subsequently removing its clips or screws.
Note the wiring connected to the solenoid and so disconnect the cables in any guild.
Remove the mounting and tab both with a screwdriver.
Remove the faulty solenoid and replace it with the new one.
Finally, replace the seat, battery, and other parts.

While you can repair some solenoids, it's frequently better to change them for longevity. In this way, you tin still have the opportunity to place your riding lawn mower on retail in the long run given that the equipment is properly maintained.
