John Deere L120 Turning Radius

Picked up a used L120 and have a problem with the turning on it. Mechanically, it appears fine. You turn the steering wheel, the front wheels turn in the direction you want, BUT you continue moving forward only gradually turning in the direction you want. The turf tyres still have a well defined tread pattern and are inflated to sidewall spec. They just seem to float over the ground. On an asphalt paved surface they do grip a bit better but still appear to float. This is all at slow forward speed roughly one third to one half max forward speed and level ground.
Thinking of getting some ag style ATV tyres for the front or would some type of front weights perform better? Any opinions to solve the problem would be appreciated.

After reading this thread I can't help but wonder, and I know this sounds stupid but is it possible that the front wheels are steering too far right or left? This would cause pushing. It's hard to understand that new tires with more aggressive tread would help when adding weight to the front doesn't help. That's a strange one. :Orange_tr
Thanks Flaken. I wasn't sure on the directional steer tires. Glad they grab in reverse as well.

Sounds like those old tires were just too hard to have any grip.

Not a stupid suggestion, Howdy Do. The wheels turn about 45° and that's at the hard stops. The problem occurred constantly and not only at those hard stops.
This is just an opinion, mind you, but I think the tyres were simply too old and became brittle and hard. Most of the people here have rather new equipment and while tyres do last a long time, there is a certain life expectancy. I asked my question because I did want to eliminate other possible causes of the new to me used machine that I got.

I have had other used tractors but the steering was never that bad. I do know that the turf tyres and my mowing area just don't mix to my satisfaction.
Just wanted to give an update!
Thank you everyone for your help here. I'll admit that I was rather hard headed and didn't really understand what many of you were speaking of. Today I replaced the wheel spindles with the upgraded ball bearings and the difference in turning is much better. The new ag style tyres work like they should now. Again, thank you all.
