I have 2 acers of grass to cut and a large Horse-riding ring 120'X80' to maintain. Cut grass once a week. I will be pulling a 4'X4' drag with a chain link fence behind it to dress up the Ring. I have been looking at some older mowers/garden tractor with a shaft drive don't mind something that needs work as long that parts are available. I am doing all this now with a John Deere with a 42" deck for the grass and a Sears mower (no deck) 12.5 B/S engine for the Ring. What are some of my options?
