So $1200 to 1400/year in gas. Probably a bit less on a 52/54" mower, but still significant.
I'm not clear on the numbers from yet.
I think it would be less on the smaller 52/54" mowers, since I'm only burning 1 gph of gas. Factoring in the higher cost of diesel, and the assumed 40% lower consumption, I would save about $1.15 per hour.
I will be mowing more hours this year (and in the future I hope), so the break-even date could be sooner. And if a diesel is somehow more productive, saving labor $$. As someone said, more hours, and bigger mowers make the best case for diesel.
Are they cheaper to maintain?
