Now this looks like the ideal machine for me.

Can handle flat or steep or rough or muddy terrain and remote controlled with 44" cut,
but the "killer" feature is that it has o board gps and "artificial intelligence / learning" technology so can learn the job then it can redo it autotomonously while you sit back and watch!
I think I could handle that!
Saw some video of it and it has tremendous traction power .. Sufficient to push a dumpmaster skip across a carpark!
