In the old days, dealers sold mainly big machines to farmers and to construction/excavation contractors who knew all this stuff. Today, there are so many of us who have property to manage, but are new to it, that a huge portion of equipment sales are compacts and sub-compacts sold to buyers who have not operated these type machines before. Dealers know that many of their customers are newbies and most are pleased to show you how things work. A dealer who is too proud to do that will not have as much business and is less likely to stay in business.
Though I have quite a few 3ph implements, I just bought a backhoe that attaches to a 4 point subframe. The dealer had a service technician deliver it and give me a full 1 on 1 tutorial about attaching/detatching and operation of the unit. I didn't have to ask, he just told me that was part of the deal.
An airplane pilot who has many thousands of hours logged is still legally required to receive instruction and be checked out when beginning to fly a class of aircraft that (s)he has not flown before. It's just a matter of being safe; anyone should learn how to operate a potentially dangerous piece of machinery before attempting to actually do it.
Good luck, and of course, have fun!!
