International b275 drawbar

Discussion in 'Classic Machinery' started by Petetheploughman, Jun 11, 2018.

  1. I currently have several International vintage tractors, sadly none of which have a drawbar. I am currently making one, I am trying to make it as original as I possibly can I'm just after the size of the two bolts in the end. Here is a picture to show you what I mean. I would like the size of those two bolts in the picture.

    Every B series international i come across is missing its drawbar - is someone collecting them - or are they lying in a huge pile somewhere?
     
  3. I know, it's nice to know it's not just me. I have come across several for sale but they are never less than £75.

  5. and what type of steel are you using,
    anything you can drill with ordinary drill bits , will just bend,

    just buy a proper one, cheapest way in the long run

    Exactly, I’ve got three tractors and only one and a half drawbars! Plenty of the frames though! I’ve got a very long Ford and DB drawbar that I’m going to bend to shape ONE day!!!
     
  7. I have some heavy duty steel which is the same size as the drawbar steel and a friend of mine is going to bend the steel for me and drill the holes. I just wondered what size the two bolts that go in the end of the hitch are.
     
  8. Pin hole looks about an inch diameter and the bolts look about half that. So half an inch bolts..

  9. If you require a drawbar I may have some lurking in the depths

    5/8 UNC.

    There's many styles of B series drawbar though, all with design differences and measurements, depending on the combination you've got, they don't fit on each others frames 20180612_112846.jpg

  12. Never seen either of those styles on a b series before? Mine are certainly different

    One on the right is on the parts list for the B275 and the one on the left for the 434 - although it shows 2 holes through the drawbar for the lower jaw and not 3 for the B275

    And they will snap, we had a spare with a tow ball welded on that broke
     
  16. How much were you towing?

    If you look at the 434 drawbar pictured, you will see that IH did not get that instruction
    Welding was safer than a loose fitting ball pin

    Snap a drawbar! Waw! Remember carting sand with a 276 with a 3 tonne trailer with about 5 in it and getting the trailer boged down on one side and tractor was still trying to pull it out with front wheels 4 foot in the air! Dad just hooked chain on front axle and pulled whole lot out with back actor on the digger. Looking back it’s a miracle that the tractor did not split in two but drawbar was still well intact!!!
