Cub Cadet Cub Cadet XT1 LT42 IntelliPOWER 547cc 42" Riding Lawn Tractor MECH-OVERHEATING Error Fix: Engine Overheating — Loss of Power

Error code MECH-OVERHEATING on the Cub Cadet Cub Cadet XT1 LT42 IntelliPOWER 547cc 42" Riding Lawn Tractor means: Engine Overheating — Loss of Power. The engine runs hot, loses power, and may shut down. Cub Cadet riding mower engines are air-cooled. Overheating can warp the cylinder head or seize the piston. Causes: (1) LOW OIL — check and fill. (2) CLOGGED COOLING FINS — grass and debris pack around the cylinder. Clean with compressed air after every few uses. (3) DEBRIS ON ENGINE SCREEN — the air intake screen on top of the engine gets clogged. Clean regularly. (4) EXTREME HEAT — mowing in 95°F+ temps with heavy load. Take breaks. (5) FULL THROTTLE — run at full throttle for best cooling (flywheel fan moves more air at higher RPM). (6) HEAVY LOAD — very thick/tall/wet grass. Make lighter passes.
