The dedicated mowers are far more agile than the lawn tractor type designs. With mine you can't mow a adjacent strips in alternate directions. (a walking box pattern is better)
However on the bright side, it is good for towing stuff.
I have got mine stuck on nearly flat ground before! There is a patch of lawn that has a very slight dip that seems to stay waterlogged much longer than the rest, at it is difficult to get enough grip on that bit to even drive across it.
