I don't think I have ever had any rutting with my PG as long as the turf is not saturated wet. If that is the case, anything out there will rut.
One thing: going up hills, the PG will spin front wheels and tear turf. Just step off the machine and walk until you clear the slope.
For the property size you mention, any ride on would work well. Esp. the Ground Logic unit is it is very nimble.
