JI Case 1660 and JD 220 flex performed flawlessly. Not many working JI Case combines left. They don't seem to get the respect the other brands do. Simple machines and easy to work on. Do an excellent job threshing , no matter the crop. I have ran them since 1975 and still get along good with them.

Beautiful, love to see that stuff. I cut a few beans with my 715IHC. As decent as it is, I fantasize about how it must have been to be in one that was new!
 
No autoheader. I made the cylinder extensions so that when all the way down the gauge on the right side shows at 1. Once in a while have to bump it up a little so as not to shove debris underneath. Pretty much seat of the pants but works extremely well, very happy with it.
 
We bought a used 800 that had never been set up right by the dealer. After I got everything adjusted and the governor set to the right RPM's, that machine would outdo a JD55.

The flange bearings were a little light on some shafts, but were cheap and easy to change. We kept a supply of bearings on hand so we could make a quick change and keep on going.
 
800 has a 32" cylinder and had 12' or 14' header, should have been about the same as a 55 same headers sizes and engine power the same, CASE always ran a bigger cylinder width than others and was this size al the way through, no "bottle necking" they said
cnt
 
A 55 had a 30" cylinder/seperator. Engine size depends on the year. They started at 45 hp and ended up over 70 hp. Far as I know everyone except IH had the same cylinder/seperator width all the way through. In fact Massey and Gleaner had a wider seperator then cylinder width. So I don't know why Case was saying "no bottle necking" as a feature. I would be disappointed if a 800 couldn't out perform a 55 of the same era. A 55 is above a 600 and guessing slightly less then an 800. But what about the 700? What size was that and were does it fit in the lineup?
 
a 600 and 700 are 40" machines 10-14' headers, big difference between them is the 600/660 had a straw rack, the 700 has walkers, the 600 also has a 50 hp engine 660 was upgraded to 60hp, 700 had 70hp as for bottle necking they said many have dead spots due to sieve width being different than the cylinder size, sorry if it sounded like I ment JD in particular, the reason I did not bring up the 700 was they were not built at the same time as the 800 which was 58-62, 700 came in 63 600 in 61 and were the bottom of the size machines in the CASE sp line, they would have been sized with a 45 correct? the 800 was a mid size machine like I was thinking the 55 was the same maybe not, when we sold machines the 1060 42" cylinder was compared to a 95 JD and the 1660 52" cylinder a 105 JD
 
I see now. I assume the 960 replaced the 700 then??? Case advertised the 600 to compete with 26-28" combines. It wasn't false advertisement as my 600 cannot keep up with my 55. Its just that some farmers looked at the width of the cylinder on a 600 and assumed it could run with a JD 95. The 55 should be compared to a 800 but its the old method of making your combine or tractor for that matter just a little bit bigger then your competitor and probably charging the same. You see JD was kinda of stuck on the separator width with the later bigger combines because they started out with a 30" separator width three 10" walkers on the 55. They just kept adding 10" to the 55 design so that you had a 40" and 50" separator width with the 95 and 105. Made for more economical and easier manufacturing but no room for "outdoing" your competitor.
 
All true, but a 105 is 49" and a 1660 is 52". Not that the three inches make much difference. My brother had a 105 JD and my 1660 would outperform it in threshing and cleaning capacity and fuel consumption as the 318 would use less fuel than the 105.
 
yes the 700 became the 900 when they added some cleaning area, then when they went to the "60" series it became the 960 until 1969 they all had the same 70hp, in 69 and 70 they turned up the engine speed and brought it up to 85hp, with the added power they also offered a 16' header at time as well, I added a couple quick shots of 600 lit for you

Thanks. Looks to me like IH and Case had the same philosophy when it came to their smaller combines because I think the IH 93/203 had 42" width cylinders. Besides more hp I think would could have improved the performance of my 600 is a bigger cylinder diameter wise.
 
you are correct on the hp as the same cylinder was used in the walker models and a Chrysler slant-six with 70hp was installed in the 700-900-960, the late 960 has 85hp I have both and only time I ever seen a need for the extra power was in 85-100 bushel Wheat with a 16' header you could hear the gov open, I really like the fuel economy they have too
 
All I know is my 600 is maxed out in 60-70 bu wheat. So is my 55 but the difference between the two combines is 10ft header vs 14ft header.
 
yes the 600 was a bit under powered I agree, funny thing is the 600/660 sold more than any other model of SP CASE combine, I would love to find a 660 dsl and see how they preform, the 188 dsl would have more lugging ability I bet they had a noticeable increase in power over the gas engine
 
Make that two of us. I'm not surprised about the sales. I know the JD 45 was their sales leader from until about late 50s to the mid 60s. That size of combine was just popular all around.
