Garden tractor lawn business? Josh

What to do when an 8 and 10 year old want to do a lawn business? Perhaps they can push a mower everywhere, but where do the clippings go? This '90's Honda garden tractor with hydrostatic drive may be just the thing. It starts and drives like a Cadillac but needs a mower belt drive clutch plate. Combine this with a small dumping utility trailer to produce a push mower + weed eater + clippings carrying + passengers mowing business.
At the community wide garage sale, we heard that the other lawn guy just quit, and there's a need.
