Had posted this in GM, but after thinking about the JD ballast recommendations, I'm really confused about the JD specs vs the Ballast Calculator. Cotton-picking cast iron wheel weights are SO expensive & will be tough for us to install...Have been contemplating our need for wheel weights on 1025r. Tires are not loaded, just have some JD version of Slime because of all the mesquite thorns that are around. Think I had a revelation that I don't need the wheel weights, unless my thinking is warped (more than usual). Max Lift at full height is 512 lb for the H120 loader. Using the Ballast Calculator, can lift 648 lb with the 260 BH OR iMatch+477 lbs ballast - neither using wheel weights. Am I missing something? Do have a couple of old 30? lb wheel weights from our long ago scrapped Sears Suburban (think they'll fit) that I'm thinking about adding. IMHO, black wheel weights are much more aesthetically pleasing than the yellow.
