61" Turf Tiger on the flat good stuff. Don't want to take one of these mowers near rocks or any debris. My field is darn near baseball ready.

52" Scag Hydro walk behind for the back yard and steep areas along the road side. Spent about a hundred extra bucks for a nice metal bag catcher to collect for my compost. This mower has superb balance on steep hills. On the newer models Scag has made the hand controlled handles much easier to operate with much more comfort.

Both these mowers will lay down diamond patterns easily. Scag makes a great deck.

Guess depends on how short ya want to keep your fields. Zero turns are not good for cutting tall grass, they are mainly for cutting very short grass, golf course stuff.
