I've had the good fortune to have been the sole operator of 3 brand new excavators in succession during my nearly 30 years with the same logging road building and rock crushing company.
'88 JD 892D LC, '95 Cat 330BLC, and a 2001 Cat 325B FM Roadbuilder h/w, which as of yesterday has 11,685 hrs. All of them (to me), were the best excavator of their times, at least the way I was using them. Pioneering, decking r/w, endhaul, pit prep, digging shot hardrock, railcar bridge placement,rip rap, and miles of cross drain pipe installs. Company wide,we have gone through 3-JD, 2 - 2nd hand Komatsus and now are primarily Cat based.
Currently 1-322C w/hammer, 322B Roadbuilder, 2006 322D Roadbuilder with forestry cab, '08 330D Rb forestry cab. 325B LC (standard excavator), JD270? w/long reach boom, and my 325B roadbuilder.
Equipment comparisons can be tough, even interspecies. The reach and power of the 325's is the same, but the Roadbuilder package blows the standard away. H/w uc with Loman finals. Climbed up 77% without pulling or pushing.(stopped midway and measured with abney on window sill). Can work 55%. By '14, we have to have replaced my 325 with one with a forestry cab,and I am curious how other brands with roadbuilder packages compare. The brand thread of yours should help my research at least towards base machines.
