One think I always liked is the softer sound they make as you work. [Reply]  [No Email]

I demonstrated a D65PX Komatsu LGP and a CAT D6H LGP both new from the dealer in '94 with 36" pads for the company I worked for, made the Komatsu literature with photos working a big ole wet stockpile of topsoil in Howell NJ, flotation is incredible given the weight of these tractors, material was soft and was like riding on a waterbed, D8K I had would not climb the pile just drive straight in, where I could negotiate any part of the pile with either of the above. LGP undercarriage replacements are obviously much more expensive, given the extra width on the pads etc. [Reply]  [No Email]
