I’m 63. I have a couple of these things in four-wheel version, front wheel drive. hey operate off of a joy stick. The extra mobility allowed me to be the saws man when putting down hardwood flooring in my home this week. I had the things ste on fast mode and the hammer man said it was like I was running at full tilt back and forth from inside to outside at the saws. Also allows me to carry things again ... I use two canes to walk, so carrying things had become obsolete behavior.
Glad the machine helped you . Someone somewhere will develope a 4 wheel drive version with mudders on it , with as much rain as we’ve had lately a 4WD is a needed thing,
