that's a lot of grass to keep up with .. over 200,000 sq ft .. have you thought of turning an acre into a wooded area for wild life ?? wild flowers and fruit bearing shrub like sand cherries for the birds .. some nut trees for you and the squirrels ??

Just a thought !!

EDIT : I have 88,000 sq ft of grass and with a 50 inch mower it takes me between 2 and 3 hours according to time of year and how tall the grass is .. if you get behind because of spring rain even a few days it will take twice as long to mow when you are able to .. this spring it has rained 17 days in March .. so you can see how quickly you can get behind .. ..
