I used to mow my runway with a tractor and bush hog. The tractor would knock down the grass that would stand back up the next day. So I would mow it again the next day straddling the tracks. So all to gather it would take 4 hours to mow the runway. Two years ago the tractor broke down and I can't get parts to fix it. So I mowed it with the DR walk behind that took 6 hours and is a lot of walking. But it looked so good. Last summer I bought the Cub Cadet garden tractor. It would take 4 hours to mow with it but it dose a great job. Yesterday I got my two pull behind mowers. Now I can get an 11' cut. Should take about 1 and 1/2 hours to mow the whole thing. The Cub Cadet is rated at 25 HP and the mowers are 13 HP each thats 52 HP . Whoopee....
