Discing

On the spray rigs those big rims are two piece and they are about as easy to change as a 15 inch car tire
 
Kewanee disks. They were a good disk and quite popular in the 50's and early 60's. The one on the right looks quite a bit smaller than the other 2, I wonder if that affected how straight it pulled?? I'd guess the left and center ones are 12 or 13' and the right one about 10', That would make it 34 or 36' wide. You could cover a lot of ground with that rig!!
 
I'd hate to have to try to back that rig into the corner of the field to get the end rows cut up. Bet it would take some doing to get it done.
 
Super 99. You are correct that the discs would have to be the same size to pull even. What you are seeing is an Optical illusion. It is the camera angle and/or focal length that make the far disc look smaller than the near disc. Counting the disc blades will confirm that the discs are all the same size.
 
I counted the blades and they are all the same size but the angle of the picture makes the one look smaller .
 
My 80+ year neighbor is all MM. I think the MM 950 may have been one of the best tractors ever built.
 
Standard practice on the open prairie is to just turn the corner. Not common to back into corners. Even today, most of the large seeding/planting outfits are multi unit, so you go round and round.

Size of the fields makes a big difference in the husbandry practices used.
 
The older generation here would have a fit if the ends were rounded off. They wanted them just as precise as the field itself, and look like GPS guidance did the job. I was taught to back into the corners with the implement or get it with a grubbing hoe by hand.
 
I have two g1000's they would not do it here. I wish I could find the pictures of me and a friend with his 820 John deere we hooked it to a 40 ft sunflower disk by a busy highway and pulled it around it was fun watching all the people stop and look.
 
I live in fairly easy working soil..A 18 ft disk would work a G-900 MM pretty hard and a 21 ft disk would work a G-1000 MM real hard...That G-1000 would be heavy if those those terra tires were full of fluid..I dont know if you can even get those tires anymore..The ElToro FWA Oliver 1950's had them..Most companies liked to show their tractors pulling more than they were actually capable of.
 
I'd add that average field speeds were slower back in that day than what we'd expect today. I'm thinking that's a 4 mph operation, possibly less. It takes a lot less power to do something like that at slow speeds.

That isn't done here. Pulling a 60 foot air drill with the tank up front and drill way back behind it is amazing to see how much land doesn't get planted in the corners. It is a physical impossibility to make a square corner with rigs this size.
I'm surprised they had rear tractor tires that size back then. I've seen a guy on youtube running a big old Oliver with huge tires front and back.
