A safety cut-off system prevents the running of a motor of a self-propelled lawn mower having left and right drive wheels, and forward and reverse gears. The safety cut-off system includes a first forward presence lever manipulatable, by an operator, between an ON state and an OFF state, wherein the forward presence lever is biased to the OFF state, and a reverse presence lever manipulatable, by an operator, between an ON state and an OFF state, wherein the reverse presence lever is also biased to the OFF state. A preventing element, which is responsive to the forward and reverse presence levers, is provided for preventing the motor from running, when the lawn mower is in neutral or a forward gear and neither the forward presence lever nor the reverse presence lever are in the ON state, and when the lawn mower is in a reverse gear and the reverse presence lever is not in the ON state.
