Be careful on uneven ground.
Narrow width, shorter wheelbase and long bale grapple might be less forgiving. If the fields are reasonably flat and level, you shouldn't have a problem, with the proper tire, wheel and 3 point balast.
Check your loader manual for ballast recommendations.
Wonder if the 4720 would be better with R1's set as wide as possible versus R4's? Flip the fronts out, too.
Wider footprint...
