I have one, identical to one shown in above photo except I have repainted mine red. I use it in my field after I have harvested crops, it is called a disk plow, however here in New Brunswick my sod is too heavy and dry to use this as a sod cutter so I use it to level my field in preparation for next years crop. I have found it useful, it works well with my 75 hp , my old 30 hp massey is too light for it.
