Equipment needed for alfalfa

I am starting a farm/ranch in Colorado and me being new to farming am wondering what equipment is needed for alfalfa? I know this is very expensive to just get started but I understand the costs. Also of the equipment needed which equipment is okay to buy used compared to new? Which pieces of equipment are worth buying new and which are okay to spend a little less on for used? I will be starting farming about 200 acres but will eventually be doing more. Thanks in advance for all the information.
