    question about weight of dozer

    I have searched and tried all I know to find a website or guide to Cat weights and came up empty. Does anyone have any idea how or where to find the operating weight of a 1952 D6 9U cable Cat with 6N winch on rear? Any help will be much appreciated.

    Caterpillar Performance Handbook (Caterpillar bible) has a section on former models

    Info retrieved from my library of original parts, service and specification manuals. Not available from any single source that I know of.

    25k seems light for a D6 although given the source I guess its right. Give a call to your local heavy hauler and see if those numbers work for their permits. My permits are for 35k to move my D6. My permits are for over width not over weight.

    9U,s were not that heavy.....highest # among specs is a 17,730 lb. operating weight. Not like the D6C's that jumped to 30k+ lbs.

    CPH says the D6 9U wieghs 17,975, i wonder if that is with ROPS??? It says they didnt start including the weight of the blade until 1967.

    interstingly enough the D6B had significant less drawbar power than the 9u but weighed 500lbs more.

    Can't always believe those rehashed stats. My original literature shows drawbar hp is same for 9U & B at 75hp with operating weights of 17,730 and 18,280 lbs. No ROPS back in them days.

    By my original spec sheets they are both rated the same at 17,000 lbs pull but under lugging conditions the 9U makes 18,700 lbs and the B gets 19,495.
