Doug: I think any weight added to the rear of these old row crops helped. Putting chloride in the rear tires of a Farmall M would give same effect as the heavy wheel on the A and SA. I can honestly say I've had a lot more thrills or chills , which ever you want to call it on modern tractors with ROPS protection than I ever had on the old H and 300 with narrow front. In the 60s and 70s I ran duals a lot on the newer 560, 656 and 1066. You get those big ones with the outside width up to 11' or 12' then you really have stability. You are right on the money, those old row crops weren't very heavy up front, and it really didn't matter what make. There have been more farmers killed with front end of tractor coming up and going over backwards than there ever was from rollovers. In the area where I farmed I know of several deaths from tractors rearing up and going over backwards. I also knew of a couple of rollover deaths neither on narrow front row crops. PTO shafts also took their toll. Speaking of row widths I see a very dangerous practice going on today in corn and bean country. They are running 100+ hp 4x4 tractors on 60 inch centers. Not so bad in spring when they have their duals on, but you see them going hauling gravety wagons 3 and 4 in a string. Some of those newer grain wagons are holding 400 + bushels. They are getting a lot of weight behind them and weight 3 and 4 wagons back is much worse than if its close to tractor. I can see a tractor like that coming off a field, making a 90 degree turn onto a gravel side road. I can see if tractor is in 4 wheel drive and those grain wagons start pulling a bit hard for several reasons. With those front wheels pulling and tractor set on 60" centers, I can see the side draft flipping that tractor right in the middle of a level road. I can also see it wouldn't be a very pleasant experience for the operator, as my guess is that tractor will go just like a slam dunk. When it happens it aint going to be pleasant, I don't care how much ROPS protection he has. I can not figure why they don't leave the duals on. You will get twice the tread wear from your tires on hard ground running dual as you will single. My 1066 peeled off a set of single tires in the first 1,000 hours. I put the duals on with all new tires and at 9,000 hours the 4 tires were still going strong. With todays farming forget your weight, get your traction from putting more rubber on the ground, it will cost you a lot less money, and may be your life.. Just in case anyone wants to question my credentials, I farmed for a number of years with as many as 9 tractors 4 trucks and 10 employees. Probably put 75,000 hours on those tractors and never had a lost time accident.
