If you are planning on aerating large properties I can't imagine any WB aerator that won't make you feel spent and spent hard at the end of a full day of using it. That's JMO, at least in regards to LARGE property aeration.
I looked at the JRCO front mount aerator, thing is I have a hard time with the thought of putting nearly any attachment on a ZTR. All I envision is the royal pita in taking the dang thing off and putting back on depending on the flavor of the day, i.e. mowing today no attachment, aerating next day put attachment on, have to mow day after that, take attachment off. I realize this scenario may be a tad extreme, provided your on the ball with your scheduling in regards to lawn maintenance, but IMO having to go through this just once would be to much in my book.
I am giving some long hard thought to purchasing a dedicated aerating setup, either a 3 point attachment, or perhaps something similar to the Z-Plug stand on.
