If you bought that new Crystal you could leave the agitator on one of the other ones all the time. Problem solved. Thank me later.I bought a new NC 3000 about 5 years ago . I had the choice of the folding type , as in in same as either of you are talking about , or the fixed model , but with hyd top link. I went with the top link model , due to not having to take off the pto .
But , mine isn't the easiest of machines to attach . You have to clamber over or under to attach the top link , and pto shaft . So , pros and cons to both types .
