Power cultivating

Okay, I'm new to the tractor thing (but I'm already addicted...). The wife and I want to have an epic garden next season and I have been doing some thinking. I just picked up a 60" King Kutter tiller and that thing will be awesome when it comes to getting the ground ready for planting I'm sure. The main question is related to the continued weeding that the garden will need throughout the season. With the new tractor available I would like to use it as much as possible so here are my thoughts:

Initially I will bust the ground up with a middle buster to dig down deep, then till it with the KK and then finally I will be making a cultivator with 6 tines. A pair behind each tire and a pair directly in the center. If my math is right with a 60" wide tractor running 15" wide R4 tires if we plant rows 24" on center everything would line up correctly and leave me about 6" of wiggle room between the plants. The goal would be to use the cultivator to weed the junk (weeds) out from between the rows right up until the plants are too tall to straddle a couple rows without damage to the them.

Once this gets to be the problem I also have a small tiller that I can set to ~18" or so width to shoot between the rows to keep them clean.

Am I at least on the right page? Any insight recommended.

Thanks,
Jim
