My Filled small R4's weigh a ton, So i would imagine filled turfs would be a lot heavier feeling. :C

I personally am not a fan of filled tires since I use my tractor for so may things, mainly mowing in the summer. I feel it's better to add weight via a ballast box when it's needed.

Same here, that is why I do not use my small R4s much, except for serious dirt work where I do not care about the surface as much as getting the job done. I do think at some point i will get my R4s filled with foam vs fluid though. I have a ballast box too.
