I'm going to get laughed at.. but the first thing I thought of was lawn tractor! A lighter tractor would be less of an issue to wrangle about a garden, it would consume less fuel shifting itself about, domestic ones get relatively few engine hour... a smaller engine might allow novel designs that get into tighter corners are simpler and cost less... You need ~10hp for a lawn tractor as is soooooo...

The only problem that I could see there is that you actually kind of need weight on a tractor. You take a 500lb tractor and take out the 150lb engine you're getting a lot closer to the weight of the driver and you're upping the possibility of tipping over significantly.

Couldn't you just adjust the driver/engine position to account for this?

From my experience with small quadbikes, I'd say that gives the driver more controll. On a light vehicle, you can just lean a bit to counter highly uneven terrain.

Chainsaws and weed-whackers might be good applications.
