Roundback vs. Squareback

[CanyonAg77]

So what"s the difference in roundback vs. square back in the
John Deere combines? I was looking at two Model 95 Deere
combines today. One has the rounded tail section, one has a
squared off housing. I thought the square might be a newer
machine, but it is an earlier S/N.

The funny thing is that they are abandoned in the grass within
50 yards of each other, and belonged to two different
neighbors of ours. Yet the serial numbers are just one digit
apart.

A squareback is a newer machine. The first rb was made from '57/58;Then the 'HiLo'(also has a round back) from '60 to '63;in'64 to '69 the squareback. It is also a better machine.Not saying a round back isn't a good machine,they are.JD changed/improoved some things with the SB 'series'.My choice would be the SB ,if both machines are equal condition.If not,pic the better one.

I don"t know the age of the machines, except they are only one serial number apart. And the older machine has the newer (square) back. So my guess is that the square back may have a rear hood from a newer machine.

Though it would be interesting to know when the change was made.

It would also be nice to find a serial number list so I can find out how old these are. I"m looking at a possibility of restoration, not working in the field.

My 95 sb has a sn of 24000.I know of one with a 54000 #.

Two machines with consecutive serial numbers is VERY cool... if both can be had, do it. You will have something no one else does, and probably for a lot less money than some much more common stuff.

Look at them closely... are the grain tanks the same shape? That changed as well as the back hood. A square back will have a different cylinder grate, different elevator chains, V belts in place of flat belts, different engines etc.

Let us know what you do... and pics are cool too!

I have two A-6 Case combines that have consecutive serial numbers

I think 20000 is where the break is between the HiLo and the Sb. 20001 Should be the first SB machine.

Are the serial number tags on the end of the fuel tanks? Could be the round back tank leaked and someone put a newer tank on it. My 1966 105 had a tank off a 1969 105. The 1966 tank sprang a leak and I replaced it with the later one. Jim

The serial numbers are in the 145xx range. Haven't had a chance to look at anything else much. One I think I can get easily, the other not so much. If the original owner were around, it would be easy. But the heirs sold the land and all the equipment on it. The buyers are a bit.....different.

Those numbers 'say' "roundback" to me.Someone could have put a square hood on one.Or changed gas tanks.

Not to be a smart you know what but if you just look at both combines, you can clearly see the differences. The SB which is the newer one will have the V belt drive to the separator instead of the flat belt. The grain tank is slightly different between the two with the SB having a larger unloading auger. The operator's platform is different too. Also, the clean grain elevator will be top driven from the beater shaft on the SB. If somebody put a SB hood on the back of a RB combine, all the other differences I listed still should be there.
