The 184 rims do not have dishes to turn in or out. They will hit the fenders if spun around. You can put wheel spacers in to move them out further. This will give you clearance for chains. (which is another option to add traction when using turf tires)
Look at tall those wheel weights on that half-track cub! Split weights on the inner front, two on the outer front, and two weights on the rear. I thought that half tracks were to provide additional traction and spread out the tractor weight over a larger area. The less pounds per square inch enable you to go into softer places. What application does the additional weight benefit?
