Well, if it is a push-mower, then the weight wouldn't necessarily have anything to do with the number of motors you would need. However, the gearing selection might have enough efficiency loss (trying to combine ~10 motors into one gearbox? Yeesh.) to increase the number of motors you need. At the same time, you might not necessarily need all 3.8 HP, so you could reduce the requirements somewhat there.

In any case--I probably wouldn't recommend putting together a bunch of CIMs for this application!
