what would be the general size that it would have pulled in the day?/
thanks for the help already. with the addition of this coe and maybe a trailer in the future to what i already have i may be selling my lawn mower, since there is no grass that is not in the shade of a ole bolt.

Vacuum brakes were used into the late 40's/early 50's and them the industry standardized on full air. Does your tractor have air brakes? If not then it would be very difficult to change it to full air and very, very expensive. | | | | | Joined: Dec 2002 Posts: 2,549 'Bolter | | 'Bolter Joined: Dec 2002 Posts: 2,549 | My '52 GMC 450 COE, http://www.classiccoe.com/friends/spanky/1952_spanky_1c.jpg was originally a hydraulic brake roadtractor. It had a Bendix vacuum operated hand control valve, that was mounted to the steering column, for use when applying the trailer brakes. That COE of yours would look great as a roadtractor. That's was the first thing I thought of, when I saw it. I've still got the fifth wheel off of mine, out in the shop, if your're interested in it. Already traded the saddle fuel tank, to another guy. | | | | | Joined: Jun 2005 Posts: 56 'Bolter | | 'Bolter Joined: Jun 2005 Posts: 56 | http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=190210824178here is the link to my coe thanks to spanky. yes semi trailer is what i was referring too. spanky, thanks i am interested in the 1/5 wheel.

I remember that they both had air brakes on them. I think that they were something like 28' long.
