same here. Switched to a modern reel mower* and my poor thin lawn has benefited. it cuts like scissors, not like an axe, and it's both small and nearly silent so mowing the lawn isn't as stressful as before, what with fumes and noise. Not saying I love mowing the lawn (it's still work, after all), but it's a very different more pleasant experience compared to a gas mower, and just as quick.
