+1 to dead axles. There are a lot of elegant ways to install dead axles for easy maintenance. We've designed (with a lot of inspiration from others) a system that allows for a complete change of drive wheels on one side in under a minute.

You could attach a double wide pulley to the output shaft of the gearbox that would be used to drive two axles, and then another double wide pulley on the center axle to drive the other. All of this can be done with COTs. The trick to getting transmissions out is to leave access to it and space around it to get it out.
