Why Exmark Lawn Mower starter does not crank?

M
Megan HuffAug 22, 2025
The starter might not crank due to several reasons: * The PTO might be engaged, so disengage it. * The parking brake may not be set, set the parking brake. * The speed control lever might not be in neutral, so ensure it is. * The battery may not have a full charge. In this case, charge the battery. Refer to the Check Battery Charge and Recommended Jump Starting Procedure sections in Maintenance for details. * Electrical connections might be corroded, loose, or faulty. Check the electrical connections for good contact. Clean connector terminals thoroughly with electrical contact cleaner, apply dielectric grease and reconnect. * A fuse might be blown, so replace it. * A relay or switch could be defective.
