Mower drive system interlocks and methods of interlocking mower drive systems with non-contact sensors are disclosed. The mowers may include two driven ground engaging means for supporting the mower above the ground; two drive systems for driving the driven ground engaging means, one of the drive systems driving each of the driven ground engaging means independently of the other drive system and its driven ground engaging means, wherein each of the drive systems has a neutral condition in which its driven ground engaging means is not being driven by the drive system; a drive system interlock operatively connected to an engine of the mower; and two non-contact sensors operatively connected to the drive system interlock, the sensors providing a signal to the drive system interlock when both of the drive systems are in the neutral condition. The methods of interlocking a mower may include steps of providing a mower having a drive system interlock operatively connected to an engine, two drive systems, and two driven ground engaging means for supporting the mower above the ground that are independently driven by each of the drive systems, the drive systems each having a neutral condition in which their respective driven ground engaging means are not being driven; sensing when both of the drive systems are in the neutral condition with a non-contact sensor; and providing a signal to the drive system interlock of the riding mower when the non-contact sensor senses that both of the drive systems are in the neutral condition.
