7 Common Causes of a Failing Gravely Zero Turn

If you put the key in the ignition and turn it, the engine won’t start. When this occurs, check for anything that could be blocking power to the starter.

If the battery is dead, the wiring and components are corroded or loose, the fuse is blown, the ignition switch is broken, the safety switch is faulty, the starter solenoid is broken, or the starter motor is broken, the Gravely zero-turn will not turn over or crank.

Before attempting any electrical repairs, the black negative battery line must always be disconnected. To avoid harm, make sure you use the Gravely in accordance with all safety measures outlined in the instructions.

Before diagnosing, repairing, or operating, be sure you’ve read and understood all of the safety recommendations in the equipment’s operator’s manual. If you are unsure of how to proceed, lack the necessary expertise, or are unable to execute the repair properly, you should seek the advice of a professional.

Fixing a Stalled Gravely Zero-Turn Mower

Your Gravely Zero Turn’s Battery Is Dead or Not Working Correctly

A dead or dying battery won’t provide the juice to start the engine on your Gravely mower. The battery’s health depends on being kept completely charged.

Since uncharged batteries can freeze in freezing temperatures, this is especially important to remember while putting it away for the winter.

Use the procedures outlined in 5 Factors That Are Draining the Life of Your Lawn Mower Batteries to check the health of your battery.

The 12-volt battery must be charged with a battery charger. Putting on goggles and rubber gloves will shield your eyes and skin from potential electrical currents. With a charger, charge the battery for your lawn mower as follows:

• Get at the terminals and batteries. A screwdriver may be required to access the battery. In no circumstances may the battery be taken out of its housing.
  
• The positive cable should be plugged in first when connecting the charging cables. The plus sign cable, or the red one, is this one. Connect the wire to the terminal labeled “+” on the battery.
  
• Connect the negative end of the cable to the battery’s negative terminal. This is the negative-sign cable, sometimes known as the black cable.
  
• Keep your hands away from anything that isn’t covered in rubber to avoid getting electrocuted.
  
• Alter the charger’s settings to achieve the desired voltage and current. Most lawn mower batteries have 12 volts of power.
• High current speeds up the battery charging process. Power consumption should ideally begin at 2 amps and rise to no more than 10 amps. A gradual charging process is preferable.

A new battery should be installed if the old one can’t maintain its charge. Your local lawn mower dealer, hardware store, or auto parts store should carry replacement batteries.

Please remember to bring your used battery. If you don’t bring in your old battery, most stores will charge you a core fee.

Problems with the Gravely Wiring and Connectors

The wires and connections should be double checked after the Gravely battery has been checked. Vibration and jolting during mowing can loosen connections between wires, cables, and the mower itself.

Verify that all connections are tight and that corrosion has not formed that could disrupt service. In the presence of moisture, connections and terminals are at risk of rusting.

Use a small wire brush and a baking soda solution to attempt removing this corrosion (2 cups water to 3 heaping tablespoons of baking soda). To clean the parts, disconnect the batteries and take them apart.

If the corrosion is too severe and cleaning is ineffective, you should replace the terminals or the component.

The Gravely Lawnmower Has a Faulty Fuse

Your Gravely’s electrical components are safeguarded by a fuse. Be sure there is no blown fuse before starting your mower.

A blown fuse can be tested by measuring the resistance between the probes of a multimeter placed on the fuse’s prongs.

Your fuse is fine if the resistance reading is close to 0. A blown fuse is indicated by an infinite resistance value.

Once a fuse has blown, it should be replaced with another fuse of the same amperage. Your Gravely should be taken to a dealer or repair shop if you keep having fuse failures.

Your Gravely Lawnmower’s Faulty Ignition Switch

If nothing happens when you turn the key in the ignition, it could be the switch. Nothing you do will get your Gravely to turn over and start.

If you suspect the ignition switch is broken, you can test it with a multimeter to see whether there is any continuity. Find the prongs labeled “B” for the battery and “S” for the starter solenoid.

Put the key in and turn it until you hear the starter sound. The multimeter’s resistance reading is taken by touching the B probe to the S prong.

A decent key switch for the ignition will have a resistance value close to 0 ohms. If the resistance reading on your ignition key switch is infinite, you need to replace it.

The Gravely Lawnmower Has a Faulty Safety Switch

In order to keep you protected, Gravely has outfitted your machine with an operator presence control system. Incorrect operation of the safety switch can prevent your Gravely from starting.

Use a multimeter to ensure your switch is working properly. A faulty safety switch can be identified by temporarily disabling the switch, however this should be done only when troubleshooting.

Never cut grass without first flipping the mower’s safety switch.

When a mower’s safety switch has been removed, it is dangerous to use the mower. It’s impossible to predict when you’ll need the protection of a safety switch, but having one is always a good idea.

Starter Solenoid Problems on Your Gravely Mower

To get your Gravely’s motor revving, you need a starter solenoid, an electromagnetic switch that connects to the beginning motor.

When the spring weakens or the copper plate corrodes, the starter solenoid can fail. The solenoid may fail if the starting is weak, the battery is weak, or the ground is poor.

You must ensure that your battery is completely charged before you attempt to test the starter solenoid. Use this guide’s additional solenoid testing methods to confirm the diagnosis of a faulty starting solenoid.

Gravely Lawn Mower Starter Motor Problems

If your Gravely won’t start, you should check the starter after eliminating the battery, cables, wiring, ground, and starter solenoid. In order to check the starter, it must be taken out.

Instead of blindly purchasing a new starter for your Gravely mower, I suggest having your local repair shop that specializes in starter and alternator repairs evaluate your starter and replace it if possible.
