I have a regular ol' 1 row King Cutter cultivator which has six tines. I have Kabota B7500 HST and it pulls it with no problems, well, unless I let the tines dig really deep (operator error for not have the top link adjusted properly).
I use the cultivator to layoff rows in my garden (most years). TIP: Don't look backwards, drive straight ahead... when you turn your head, you'll turn your well and have a curvey row.
