RCMEDIA,
califr's post was responded to previously with advice about what he was doing wrong. There is a learning curve with the computer and DPF equipped, higher horsepower Tier 4 diesels. And I agree that the EPA rules are a bunch of BS. That said, there is no way that a 2650 has the power of the 3350. Ain't happening - you would lose that bet. The 3350 also has a clear advantage at higher elevations (I live at 4900 feet) were a normally aspirated engine loses about 3% per 1000 feet elevation, the turbo supercharged engine does not.
Operated correctly, the DPF and auto regen is pretty much transparent, I pust the button after engine start. If it needs a regen while I'm running it, and it does that about every 13 hours or so, then it takes care of that automatically. I've only had it do a parked regen twice; once when I forced it to do that to see what would happen (I didn't allow it to auto regen), and then again when I was using the tractor for short periods and so didn't push the auto regen button. Pretty much a non event, took 15 minutes or so.
If I were making the purchase decision again, I would certainly consider the 2650, but the 3350 is a better fit for me I think.
