A control system is used with an associated mower having a cutting blade, a drive shaft for rotating the cutting blade, first and second drive wheels, and a power train for driving the first and second drive wheels. The control system has an electric clutch for selectively coupling the cutting blade to the drive shaft, first and second handles for independently driving the first and second drive wheels, first and second switches selectively switchable between first and second positions, a relay for electrically connecting the first and second switches to the electric clutch and control rods for mechanically connecting the first and second handles to the first and second switches. First and second handles are placeable into reverse positions. This causing first and second bell cranks to rotate about a control shaft which lifts first and second control rods. When the control rods are lifted, first and second switches are switched and power is disconnected to the electric clutch. The cutting blade is thereby detached from the drive shaft.

[ Having thus described the invention, it is now claimed:] [1.] A control system for use with an associated mower, the mower having a cutting blade, rotating means for rotating the cutting blade, first and second drive wheels, and driving means for driving the first and second drive wheels, the control system comprising:coupling means for selectively coupling the cutting blade to the rotating means;first and second driving control means for independently driving the first and second drive wheels respectively, said first and second driving control means each being selectively placeable into reverse positions, said reverse position of said first driving control means for use in driving the first drive wheel in a reverse direction, said reverse position of said second driving control means for use in driving the second drive wheel in a reverse direction; and,first and second switches selectively switchable between first and second positions, said reverse position of said first driving control means switching said first switch into said second position, said reverse position of said second driving control means switching said second switch into said second position, said first and second switches selectively deactivating said coupling means only when said first and second switches are both in said second position.
