Market Garden/3 point hitch tools

I have a 3 acre market garden and currently use a 2 way IH plow, 8′ single gang disc, and 6′ spring tooth for field prep. I have used riding straddle row cultivators elsewhere and tried it here a couple years with difficulty (rocks and some minor slopes) for making beds and cultivating. I used a single horse and adjustable walk behind cultivator last year which worked pretty well, but does not allow for raised beds which are a near necessity in our one field that has some pockets and slopes where water can sit after heavy rains. This year I used the Annies All in one for bed making and attempting to cultivate. The rocks pushed it around a bit much given it’s light weight,and without a solid wheelbase frame to hold the cultivator I could not get it to work to my satisfaction.

I am looking at re-envisioning my market garden setup with 2-3 horses and using already familiar, functional, and available 3ph tools is enticing.

Does anyone have experience with horses and 3 point hitch tools?

I and J has a manual lever lift setup and a hydraulic lift setup on a pull behind cart – anyone seen these in action, particularly the hydraulic lift?

Any other options out there?

I am looking at a 60″ wheelbase forecart for 60″ beds with attachment for the following

– bed shaper(http://www.marketfarm.com/cfms/lesche_bed_shaper.cfm)
– Kress cultivation setup, 2 rows (some crops would be 1 per bed)
– Perfecta? Available used, though I am curious to hear folks with culitmulchers and how they compare if I would have a means to lift the 3ph tool.

Any other tools you would use if you had 3ph capabilities? No PTO.

Side question – any suggestions for dealing with many fist sized rocks when cultivating or tilling? Besides picking. I have heard the meeker harrow on the lesche bed shaper will push down the rocks a bit for shallow cultivation, any thoughts?
