I would appreciate some thoughts/opinions from anyone who has had the opportunity to spend some time around any of these machines, specifically the E50 and E55 with the 2.4L. In reading other forums it appears a number of operators are having trouble with these engines in skidsteers and track loaders. Most complaints seem to be related to cold temps and fuel. Other manufacturers bash bobcat for going away from a DPF, are they just jealous? Thanks
