    What to do if Exmark Radius E starter does not crank?
    • U
      urodriguezAug 17, 2025
      If the starter on your Exmark Lawn Mower doesn't crank, it could be due to several reasons: * The PTO might be engaged. * The parking brake might not be engaged. * The drive levers might not be in the neutral lock position. * The battery might not have a full charge. * Electrical connections could be corroded, loose, or faulty. * A fuse might be blown. * A relay or switch could be defective. * There might be a faulty module. To resolve this, disengage the PTO, set the parking brake, ensure the drive levers are in the neutral lock position, charge the battery, check and clean the electrical connections, and replace any blown fuses. For issues with the relay, switch, or module, contact an Authorized Service Dealer.

    What to do if my Exmark Lawn Mower is losing power?

      If your Exmark Lawn Mower is losing power, it could be due to several reasons: The engine load might be excessive, the air cleaner could be dirty, or the oil level in the crankcase might be low. Additionally, check for plugged cooling fins and air passages, a dirty fuel filter, or dirt, water, or stale fuel in the fuel system. To address this, reduce the ground speed, clean or replace the air cleaner element, add oil to the crankcase, remove obstructions from the cooling fins and air passages, and replace the fuel filter. For issues with the fuel system, contact an Authorized Service Dealer.

      Abnormal vibration in your Exmark Lawn Mower can stem from several causes: bent or unbalanced cutting blades, a loose blade mounting bolt, loose engine mounting bolts, loose engine pulley, idler pulley, or blade pulley, a damaged engine pulley, or a bent blade spindle. To address this, install new cutting blades, tighten the blade mounting bolt, tighten the engine mounting bolts and tighten the appropriate pulley. For issues with the engine pulley or blade spindle, contact an Authorized Service Dealer.

    What to do if my Exmark Lawn Mower blades do not rotate?

      Juan FosterSep 1, 2025
      If the blades on your Exmark Lawn Mower aren't rotating, it could be due to a worn, loose, or broken drive belt or deck belt, the deck belt being off the pulley, a broken or missing idler spring, or the drive belt not being routed correctly. Check the belt tension, install a new deck belt, install the belt on the clutch and deck pulleys, idlers, and tensioning idler per the routing decal on the deck, and replace the spring. Refer to the belt routing decal on the deck for proper routing.

      If your Exmark Lawn Mower isn't driving, possible causes include the drive release handle not being in the “operating” position, a worn, loose, or broken drive or pump belt, the drive or pump belt being off a pulley, a broken or missing idler spring, or low or overheated hydraulic fluid. Position the handle in the “operating” position, change the belt, replace the spring, and add hydraulic fluid to the reservoir or allow it to cool down.

    Why is my Exmark Radius E Lawn Mower cutting height uneven?
    • C
      Christian Martin Jr.Sep 9, 2025
      Uneven cutting height on your Exmark Lawn Mower can be caused by several factors: blades that are not sharp, bent cutting blades, a mower deck that is not level, a dirty mower underside, incorrect tire pressure, a bent blade spindle, or uneven blade tip height. To fix this, sharpen the blades, install new cutting blades, level the mower deck, clean the underside of the mower, adjust tire pressure, and replace blades, spindles and (or) check for damage to mower deck. For issues with the blade spindle, contact an Authorized Service Dealer.

Other potential causes include a dirty fuel filter, dirt, water, or stale fuel in the fuel system, a dirty air cleaner, a malfunctioning seat switch, corroded or loose electrical connections, a defective relay or switch, a faulty spark plug, a disconnected spark plug wire, or a faulty module. To resolve this, fill the fuel tank, open the fuel shutoff valve, add oil to the crankcase, ensure the throttle and choke are correctly positioned, replace the fuel filter, clean or replace the air cleaner element, check the seat switch indicator and replace the seat if...
