I am semi-retired from IBM and considering going into some kind of light excavation business using my Bobcat. I have a trailer and a truck to pull it. I realize I need to get more attachments but am not sure which ones would make the most sense to start. I want the Bobcat to be the core of my business and would not want to be a general landscaper for example and only use the Bobcat once and awhile. With a dozer blade I could grade, a harley rake and roller I could do dirt driveways, and with a rock hound I could do lawn prep. Cannot afford many attachments right now, maybe just 2. So what attachments to start and what specialization to consider.
