I'll find out! The measurements I've seen from others have been lower. > ... I think this is more efficient than a hydrostat. Almost certainly.

If you have hills to mow, here > are some considerations: I have one swale to mow that I don't feel is safe with the ICE, let alone higher CG from batteries, so I'm looking at laying pipe and filling it to a mild, safe grade, even without the conversion. That's the only significant tipping grade. When I don't mulch, I bag, and I can't both bag and tow. I've thought of trying to hang batteries off the side but I can't see a way to make it work without interfering with the pedals. Since I won't have much grade, I'm planning to follow in Joe Lorenzi's tracks and use four group 27 lead acid deep cycle batteries. 110Ah at 20hr. I'm going to see whether I can fit group 31 instead but I know that to do that I'll have to do more modification, and it's already going to be interesting building a bigger battery box under the seat even for a group 27. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
