For general recommendations I would say:
Tractor: 50hp or greater. 4wd is a plus, not always necessary and depending on the year class of tractor/price you are looking at this might not be an available option. 3-point is close to a must especially depending on implements you buy. Im a John Deere boy my self, but a solid well kept tractor is just that. If not buying a some what new tractor I would recommend putting the emphasis on previous owner, up keep, and consider any hydraulic implements you plan to buy and the hydraulic adaptors to each implement (can get to be a big burden). I also strongly recommend a wide front tractor if buying older models (not narrow/2-wheels paired under hood).
Implements:
No-till planter would be great. Other than a no-till I would also recommend a plate planter, or 3-point mounted planter. Any of these would be great options.
Brush Cutter is a great implement to have
Cultipacker is a great implement if planting alot of larger brassica plots. If these plots are going to be small you can either buy a small 4 wheeler packer or pack with 4 wheeler tires.
Tiller- Would be an awesome tool for small and mid sized plots. But in my honest opinion I don’t think you need or would want to run a tiller for planting say a 6 acre corn/bean plot. Could get very time consuming. They are awesome tools and I wish I had the money to buy one, but totally impractical for most all my plots.
My brother and I bought all of our equipment over a period of about 2 years. We did not have a huge budget so we searched and waited around for deals on used equipment. Everything from old equipment around the farm, family friends, craigs list, and driving to farm houses with old equipment visible from the road.
If I had to do it again, Im not sure I would change much other than budget 
I would say to successfully plant our 27 acres of plots (corn, beans, small grains, brassica, clover, sorghum) I would be looking for this:
Tractor: Older model John deere 3010/4010, Allis D19, or comparably International. I would for sure get a wide front tractor and be looking at diesel models. ($5k range)
Tillage: I would pick up an old disc that has the capacity to support a hydraulic cylinder. Get a cylinder off a farm auction that closely matches my hydraulic needs ($300 for disc, $100 for cylinder). Also I would buy an old Ag digger ($500 range or less with another $100 cylinder).
Brush Cutter: Buy a used 3-point woods mower, or old school 2-4 row stock cutter. ($100-500).
Planter: I would buy any decent deal on a 3-point 3-4 row planter, 4 row plate planter, or old 6 row air seeder and convert it to a 4 row 30″. I would also buy a large capacity 24 volt broad cast seeder for small grains and fertilizer. Buy one that either mounts, or could be fabricated to mount to 3-point on tractor. ($250-500 depending on size).
Extras: I would be sure to have a rigid harrow/yard rake that can be drug by 4 wheeler in order to really break up brassica plots so large chunks don’t bury seed during packing ($20-40). Cultipacker, probably in the larger 4 wheeler size so that it is easily drained and moved/transported along with drag in one trip to plot as well as accessible to small kill plots ($100-250 new). Sprayer, 25 gallon 4 wheeler capacity with extendable booms, build a mount for either 3-point or 4 wheeler rack ($300 new). Other than that, Id say some small hand broad cast seeders for small secluded kill plots.
I guess alot of choices depend on money for equipment, and time to put it to good use. I know this got long (sorry), but hopefully you or someone else reading this can utilize it in one way or another. Good luck with finding your desired equipment and hope it helped out 
! The question is shopping for what 
. I have a rough idea but wanted to hear from some experienced food plotters. My main questions are on horsepower, brand and combinations of implements? I want to be able to plant between 20-30 acres a season of all sorts of variety in areas between 1/4 acre to 6 acres large. If I had to guess right now I would say 50 horse, John deer or kubota, 4 wheel drive and 3 point. For implements I was thinking a no till planter, roto tiller, brush cutter and cultipacker? Wondering if any of you had to start from scratch what you would buy? I also have the luxury of not ” needing” any of this until before next spring so I can spend some time shopping 
thanks for any input and suggestions, I currently know next to nothing about heavy equipment like this but I need to get started.
Kubota, John Deere New Holland are all good choices for tractors 
. We have a respectable budget and renting implements as needed is not out the question. I want everything I need but nothing more and nothing less (I know that’s not exactly reasonable 
thanks for the replies!
Could plant some serious plots with that thing though
