The most common causes are a broken or slipped drive belt, worn transaxle, or disengaged clutch cable. Before ordering parts, check if the belt is visibly cracked or off the pulley. If the belt looks fine, the transaxle or internal transmission parts likely need replacement. Genuine OEM parts ensure proper gear ratios and engagement.
Look for the equipment nameplate on the frame (usually under the seat or on the rear panel). It contains the brand, model number, and serial number. Write down the complete model number before shopping—transmission parts vary significantly between models, especially for, and brands.
Often, yes. If your mower has no drive but the engine runs, start with the belt and idler pulley—they're affordable and frequently the problem. However, if you hear grinding or feel resistance when shifting, the transaxle itself is damaged and requires full replacement for safe operation.
A transaxle combines the transmission and rear axle into one sealed unit, common on mid-size and riding mowers. Smaller push mowers often use simpler transmission belts and pulleys. Check your manual or model number to confirm which type your mower uses before ordering replacement parts.

Check the frame beneath the seat, the mower deck, or the engine housing for the equipment nameplate. It usually lists the complete model number along with the brand and serial number.
