We’ve been using a rotary plow and power harrow for about 12 years and find the flexible use tools to be of bigger benefit than single use tools. If the tilth is good, the plow is great for creating raised beds and a light raking of the top of the row is sufficient for planting. If more precision planting is required, a pass with the harrow does and excellent job. Here’s a link to the plow: https://www.earthtoolsbcs.com/implements-soilworking/rotary-plow/
Over the last couple of years, we’ve tried to reduce the tillage by using permanent rows. When we’ve need to reshape the beds, the plow puts soil from the gullies (which have been getting wood shavings and compost as mulch) back on top without tilling the planting surface. Shallow tilling is sufficient if weeds have been reasonably well controlled the year prior.
We’re rarely plowing a large plot any more and the plow seems to still find excellent utility. Just our experience, of course.
Have a great season!
