So here is a question I think I already know the answer to. First, what is the flow rate on on 743? I guess this also depends on how strong the hydraulic pump is. Is it possible to covert this old machine to a high flow system? I am assuming not. In order to run attachments such as one of the new disc mulchers; that grind up trees and brush, it takes a lot more flow than a 743 can produce.
