Air filled tyres on my 4105... of course I'm dealing with an incredible 2% gradient on my sprawling 6 acre property.
My land does not have a spot that has no slope, so my 4105 has fluid filled rear tires,,
I still need to engage 4WD going down some hills while mowing, so that the rear tires do not spin,,

I am a fan of fluid,, but,, the JD 650 does not have fluid.
the base weight of the tractor is plenty for the 14HP of the 2 cylinder engine,,

If anything, I may add fluid to the front tires, the 650 does act front light,, I usually carry two suitcase weights.
As far as ride, I think fluid makes the ride softer.
I added fluid to a Cub Cadet GT, all 4 tires, and it made the ride much smoother, kinda like adding shock absorbers.
With fluid, you have to be careful not to over pressure the tires,,
there is VERY little room for air, so the pressure becomes critical.
And,, rust from CaCl,, the rears on my 584 IH did show rust,,
I found new tires with rims when the tractor was 40 years old,,

BUT, I sold the old tires and rims,, the guy was glad to get them,, even being 40 years old,,, :thumbsup:
I fluid filled the new tires the same day I mounted them on the tractor,,
With that loader, fluid is a MUST!! :dance1:
