Oh, I would expect it to alter the outcome a very great deal! I would absolutely have preferred a heavier machine. I mean, I'm a normal tractor admirer, bigger is better. But, then, tuppence is tuppence, right? And I'm just small change.
I had a 4 hp riding mower when I was little, the blade removed. One of my friends had a mini-bike. Another had a go-cart. But I loved that thing. With that as my first experience, I'm appreciative that I wound up 50+ years later with what I do have. And I completely believe you about the weight!
