Hi, first post on the forum. I have a small solo lawn care business and I have been wanting to upgrade to a self propelled older Toro commercial mower with a Suzuki engine. There's a few for sale around me for a reasonable price, and I'm debating between the 2 stroke and the 4 stroke. What would you recommend? I cut on average 3-4 lawns per week, and occasionally very tall and thick grass, knee high. I'm leaning toward 2 stroke but open to suggestions, thanks.
