Actually, the dealer is getting the R4s at my request. I figured they would be better for mowing than the Ags. I also thought the filled tire ballast would help with FEL work. This dealer is 2nd or 3rd generation as a dealer (mostly Massey-Ferguson) and farmer and seems pretty confident in his assessment of calcium filling.
Rust issues aside, do you think the extra ballast will adversely affect finish mowing (tearing up the sod)?
