I priced a large tractor from the local JD dealer, just before I got the 4105.
The salesman said they automatically load the rear tires if a loader is ordered.
There was no mention of cost, free, charged, etc,, they just rolled fluid into the price.
I have never,, in 20 years, used ballast on the 3 point hitch on my IH 584,,,the tractor is 40 years old, and it works just fine.
If there is something back there it is by coincidence,, not by plan.
What would the 584 carry back there in scale to adding weight to a 1 Series?
The 584 weighs 10,000 pounds,,so, would I need three tons?...
What I am saying is the salesman sells a big tractor, rear ballast is never discussed,,,
The smaller machine, which he sells few of,, needs special options,,
