How often are you people mowing your lawn that that's even a concern? It's like this is "surburbs: the problem: the comment section"
I feel you're dealing with a different level of lawn mowing if you're towing a mower, not pushing one.
From that perspective, it's like someone going over their strategies to avoid overloading their car's suspension when they're buying groceries. That's not a "thought and attention" scenario, that's a "why do you have half a ton of groceries" scenario.
