McCormick grain drill models ?

riverbend · Jan 5, 2012

Is there a reference that lists and shows all the McCormick grain drill models ? I'd sure like to find a manual for one of mine, but when I look at all the stuff on eBay, none of them are quite right.

This drill is a tractor pulled, high steel wheel, trip lift, single run, 10 foot double disk drill.

It has RW-560.C and 20-DD stenciled on the right side. It has another number (4726?) stenciled inside the box. I'm guessing that 20-DD refers to the fact that it has 20 double disk openers. I can't find any mention of a RW drill.

Thanks

I have a broken spring in one of the lift clutches and without knowing the model number or part number I am kind of stuck. Unless someone has a spring they could measure...

That RW-560C seems like a part number to me. The sequence seems to fit, for instance the fertilizer feed wheels are NC-316, I have a hay rake with a casting no. RA-315... There is stenciled numbers all over my McCormick 10-7 drill, which is 10 holes, 7" apart. I don't know what model my drill is,either. 10-7 is stenciled on the frame in some obscure place, and offers no hint as to what it means. When you say 'single run', do you mean fluted feeds? I always thought everything up to fluted feed was 'double run', (in McCormick models) which was a split feed cup with the feed wheel in the middle. One side of the wheel had heavy flutes and the other side was fine flutes. Each seed cup had a little cover that you could switch from one side of the wheel to the other, depending what kind of seed you were planting. In this rather lengthy answer to your question,"What model is it", I suggest that the drills had no model designation prior to the No.10. They were simply known as McCormick-Deering 20-hole drills.

have you tried searching the wisconsin historical society site?

Not exactly easy to find useful info there, but probably your best bet.

As Firtz said, there's a good chance there was no actual "model number" -

I know my hay rake is just called a "Enclosed gear 4 bar side delivery rake" - there is no model number. I found that odd - it's from the late 40's so it's not THAT old. Figured everything would have some kind of number by that time period.

There is only one opening for the seed cup. The feed 'roller' is fluted. I might not be using the correct terminology with that. It looks a lot like the M drill, but the land measure (acre counter) is much simpler and does not go nearly as high.

Your terminology is correct. Actually, Mine is more confusing than yours is, with talk of fluted feed wheels. Why don't you go to your local dealer and ask them to pull out a book on a No. 10, just to see how far away it might be? To change the seed rate, do the fluted rolls slide in and out of the seed cups, or do you change the speed of the feed shaft?

The feed rolls slide back and forth to change the seeding rate.

I hate to sound so dim, but that's a great idea about going up to the dealer and ask to look in their parts books.

So far I have everything working except for a few openers. Some of them are missing the dust cover, spring, and seals. One of them is missing the cast washer. I think I'll take one apart and see what's stuck inside.

Thanks for the tip.
