Tale of Two Straw Spreaders

The combines had a straw spreader attachment that was mounted in the straw hood. It is not to be confused with the straw chopper which pulverized the offerings much better. Anyway here is a pic of one in action with the belt drive arrangement I am familiar with via the special attachments parts catalog I have:


It requires an extra belt.

However, in a discussion at allischalmers.com

I recognized a second style of belt drive. Looks to be a little simpler/efficient. May be using the same separator drive belt if the idler was re-positioned to give more slack. I wonder which came first/was better…anyone have a parts list/info on this version?

    My parts book shows the two different drives. They both require a pulley and belts added to drive the spreaders. One drives from the separator drive shaft,this is the second type drive .like the one in the top picture and needs a twist in the belt. The first type drive is like the second picture and also has a second pulley and belt but drives off the straw rack pulley. The second type drive requires a spacer on the shaft then bolt pulley and spacer together with the other pulley. First type bolt pulley to straw rack pulley.

    Both types of drives are shown in Dealers parts catalog SPECIAL ATTACHMENTS for “60” series all crop harvesters July 1959 form D-28 for those who would like to have a better look at the type of drives .

    Thanks Chris. Will check out my Special Atachments Catalog again. I don’t recall seeing two arrangements but perhaps I missed it. What page would the second type be on?

  4. Chris Hedding says:

    Page 59 in the book I listed .both drives shown. First type in lower right corner.

    Chris, looked again and I see it..How did I miss it? Anyway, the first type sure looks simpler. Wonder what the reason is for the change to the second type?

    Belt slippage and would cause the straw rack to slow or nearly stop if too much straw going into the straw spreader.

      Aha! That would make sense! Oh well I shouldn’t feel bad for not figuring it out; after all the people they paid to design it got it wrong too 😉
