How important is it to have 4X4 on a small (sub compact) tractor? I am looking at two tractors (will leave names out to avoid pissing match) and one is only 2 wheel drive. Of course its cheaper, which is very appealing, but how important will it be to have 4X4 do you think? I will use it MOSTLY for repairs and such to existing lawns, so it won't be important there, but will occasionally use it in muddy areas. How easy is it to pull a 2 wheel drive sub compact out of the mud? Thanks guys, appreciate the help!
