New to the forum here but longtime Kubota owner. Considering purchasing a B7500 with turf tires for my Christmas tree farm. I understand the 7500 has adjustable wheel spacing. Does anyone know the width at the narrowest setting with turf tires? To fit down my rows I need the tractor to be in the 40-45” range. Also, are there any other models with adjustable tread width I should. E looking at? Much thanks for any help.
