(ET) E-12M and obstacles

[Steve Gaarder <gaarder ecovillage ithaca ny us>]

We're eyeing that E-12M on Ebay.  One of our concerns is mowing trails;
the ground can get rather rough with a number of gullies to cross and our
E-15's front-mount mower can't handle it. I'm thinking that the E-12M,
with its mid-mount mower, could handle this stuff better.  One concern,
tho, is the size of the wheels.  Are the E-12's wheels the same size as
the E-15's, or smaller?  Any comments on how well an E-12M handles
difficult terrain?

thanks,
