Thanks a lot for the detailed answer. I will stick with a single bottom if I find one to purchase.
I don't have the multiple field tedium problem of the single bottom that you did because I am only tending a vegetable garden of roughly 1/4 acre.
I think you are making much more use of your tractor than me. Its just the little garden, dirt driveway maint, snow removal ( I added a strip of car tire to the blade for snow scraping) and general project stuff around the yard.
Have a good upcoming weekend!
