I don't like to run any tractor at the higher RPM that the DPF engines seem to require.My advice is to ask people who don't like them. Find out why.
It’s not a common thing. Start a poll of how many people have had to replace their emissions systems. Doubtful that many will have done this.Also, you shouldn't ask people who have had no problems. Ask the people who had to replace their emissions systems. Find out what it cost and how long it took.
