MM GVI 2WD does not turn sharp

I noticed that my GVI does not turn sharp at all. It seems that the wheels are moving against their stop as they should.

Why do the MM turn that bad, compare to any other 2WD tractor I have ever seen?
 
To put a number to it, from Nebraska, Turning radius without brakes:

GVI 229''


JD 4020 146''
Ford 8000 156''
1000 Vista 147''
JD4850 2WD 181''

Only worse tractors would be:
G706: 251''
 
Tractor that size at the time wasn't made to work in a garden, just big open fields with large wide machinery behind it, that doesn't need to turn sharp. Wasn't a cultivating tractor. Just my thinking.
 
The wheelbase is actually slightly less than a 4020, a foot less than a 4850 deere, yet it still takes much more to turn it around.
I have a 55MH and it turns sharp.
 
Yes. So 20% less than gvi. About same wheelbase for 5010.
I tgink thats a little design flaw of the gvi. That and the ergonomy of the hydraulic and the commands in general. Everything is operated from the right hand. At leat the scv levers could have been out on the left.
 
I had a 705 that I bought and was bad stuck so I parted it out . It had the set back front axle to reduce turning radius. I know this was an option on the 707 as I have seen literature, but not sure if it was put on my 705 at a later date. You use the front axle you have on it now, but a mounting plate
and much shorter wishbone moves it rearward. I still have the prices if you were interested

Yep, I have seen those GVI with shorter wheelbase.
It is interesting that MM knew about the issue and choose to make a shorter wheelbase version (that probably has quite poor steering), rather than fix the issue, change the steering linkage, and have wheels that actually turn more than 25 degrees.

The problem is coming from the drag link system hitting the tires. They could have fixed that by connecting the drag link to a bell crank attached under the belly and thus get super sharp steering angle.
