I'll agree with everyone else's comments about the grass getting blown into the rows. It can bury young plants and it's no fun trying to clean grass clippings from salad greens. I've gardened on as much as a half acre. Now we're down to about 1/10 acre, but producing as much or more with less effort. We're planting closer and going vertical as much as we can. I may end up moving the melons and squash to a different area next year because they do invade everything else with the tighter garden arrangement.
I haven't had much luck with Cub Cadet primary tillage equipment, probably because I have heavy clay. A Cadet will hardly pull a moldboard here, and I'm okay with that because I shouldn't be using one anyway. It's amazing how fast they'll create hardpan. I used it once--never again. The Brinly discs barely break the surface unless I've got enough weight on them that I'm way past the point of being able to lift them with the sleeve hitch.
My tiller hasn't impressed me yet, but that's primarily because I have it mounted on a 123 that won't maintain a steady speed. It will be on the 126 next spring. So far, my BCS is faster and does a much better job.
The Brinly cultivators work very well for corn, bush beans, and other row crops once you get them set up properly. It just hasn't been worth taking the time to mount to the tractor for the little bit I need it these days.
My favorite garden tool for the Cub Cadets is my Trac Vac. We mulch heavily. I've been using alfalfa as a garden mulch for about 6 years now. I maintain 1/4 acre of alfalfa just for mulch. Before the Trac Vac, we had been cutting it with a sickle bar and hand raking. Now I cut it with the Cub Cadet and vacuum as I go. Once plants are big enough to see, we start mulching and never cultivate again. A 6-10" layer of mulch does a pretty good job of suppressing weeds, eliminating erosion, and retaining moisture. I also use grass clippings and leaves. So far we haven't had any problems with the high nitrogen mulch--probably because we don't incorporate it. We did have trouble a few years ago with a heavy leaf mulch--potatoes tasted like oak leaves.
I'm wanting to start experimenting with minimim-tillage or no-till in heavy mulch. That may involve narrow strip tillage (6-8" wide). I have a spare Cub Cadet tiller now to experiment with.
I also plan to build some hilling & furrowing attachments, a planter, sub-soiler, and maybe a disc-plow for breaking new ground.
BTW, Squash, gourds, and hairy vetch are all good raccoon and deer deterrents in the corn patch. It was recommended to me. This year we had gourds running rampant through our corn and the deer didn't bother it. Supposedly deer and raccoons don't like to walk through thick vines.
