If your Ferris Lawn Mower rider won't drive, check these items: * The hydraulic release valve(s) might be in the "open" position: Turn the valve(s) clockwise to close them. * The belt might be broken: See Drive Belt Replacement. * The drive belt might be slipping: See the problem and cause below. * The brake might not be fully released: See authorized service dealer.
