Purchased from FIL in 1989, and have used to consistently farm 42 acres in Maryland. Performance has been goo but some things are problems.
One example of this is the RoosaMaster diesel return plastic fittings. Pop one of these in the middle of a field on Saturday and your out of commission for 2 days. Yes, I keep spares, but they can fail quickly at times also. There is some oops engineering, but probably no worse than any of the competitors.
