Everyone is telling you to go big but if you can get by with 25hp you won't have to have tier 4 emissions...
This sounds important but I don’t know what that means. What are tier4 emissions and why are they bad?
My Kubota MX5800 has a Regen Burn and it tells you when you need to do it.
No DEF to add to it.
The DEF is for larger engines
