Regarding the raised bed cropping system I use:

Here are pictures of the equipment used: John Deere 3020 tractor,
Roll-A-Cone hiller-bedder, Howard Rotavator, tillage tool (spring shank
cultivator), 3 bottom plow. I have three Yeomans plow shanks which are
mounted on the 6' toolbar pictured below (YeomansPlowToolbar.jpg) and applied
to the entire acreage when soil moisture in low enough to avoid compaction.
I farm on a number of converging slopes so erosion is a problem, access
by tractor is also. I plan to build small temporary earth dams across
all the beds on all slopes at 100' intervals to limit erosion. I have
dug small ponds in three locations to catch nearly all runoff from the gardens.
The tall, long raised beds were prepared across the grade on the flats, along the slopes on
the contour around curves and on long runs with the grade with cross-beds at 90 degrees as
low dams every 100' for erosion control and water retention; they contain nearly all rainfall
and dispense it gradually during dry times, by soaking up into the growing beds.
During heavy rains the beds look like chinampas and the catchment ponds fill up.

I have added improved hilling disk hub/axle/mounting assemblies to the Roll-A-Cone hiller-bedder
and a row of 4 20" tillage tines with chisel points along the rear toolbar,
between the disks, for extra seedbed tilthing, widening and levelling,
cutting narrow planting furrows and plowdown of crop stubble and weeds.
