With my
BX23 I went with the Landpride reverse tine. Love it but wished I had gotten the slip clutch. Will bury itself in sand so takes a bit of getting used too to keep it level and best in high range. Dark top soil ground it works up just great and levels out oh so nice in low range and goes as deep as it will go keeping the RPS up. Clay is the same as top soil just have to run forward speed slower keeping the RPM up. Clay and rocks do not go well with this unit as it will snap the sher bolt after hitting any size rock that it can not bring up to the surface, so it takes several passes, then picking up the rocks and doing it over and over until you get the depth you want. So buy dozens of of shear bolts if soil is rocky and hard unless you spend the extra $ for the clutch.
The forward unit on my JD 322 in clay would climb itself out of the ground and bounce over the rocks until loosened up. Broke shear bolts but not as many. But once you have the area cleaned out of rocks the reverse tine for me does a much nicer job finer job.
