PTO time causing problems

[Brock]

If removing the mandate is not something you want to do, Change your pto ratio... instead of setting your pto to run with your truck at 1000rpm, get it geared to run with your truck at 1300 or 1500rpm. Will be loud as hell and your fan will go off constant but there will be enough heat to keep it cleaner.

I work hauling crude oil and have the same issue and I honestly believe that these emis sion systems cannot be on oilfield equipment so they either need to be taken care of or oilfield guys need to rebuild old trucks or buy gliders.
