durallymax,

Interesting, I just finished doing a week long demo evaluation of a Volvo L110G Interim Tier 4 for my employer. The Volvo Rep, informed me that it is indeed a DPF system and the SCR needing DEF won't become available until mandated in 2014.

I can state with absolute certainty that a Volvo L110G is "one hell of a machine". I conducted an extremely thorough field test and evaluation and the 110 aced every task I threw at it with flying colors.
