Ryobi Ryobi RY401110 40V HP Brushless 21 in. CrossCut Push Mower BLADE WON'T ENGAGE Error Fix: Blade Will Not Start Spinning

You pull the blade engage lever (bail bar) and pull the trigger, but the blade does not begin spinning. The safety bail bar on the handle must be held against the handle while pulling the trigger — both must be engaged simultaneously for the blade to start. This is a safety feature. If both controls are engaged but the blade does not spin: check the battery — a depleted or faulty battery cannot deliver enough current to start the blade motor. Try a different fully charged battery. Check that the battery is fully seated and the contacts are clean. If you hear the motor try to engage (a brief hum or click) but the blade does not spin, a foreign object may be jammed between the blade and the deck — disconnect the battery and inspect. If the motor does not respond at all, the blade motor or controller may have failed — this requires warranty service. Also check that the bail bar cable or switch is functioning — if the cable has disconnected from the safety switch, the motor will not engage.
