I'm looking at a B2320 narrow in the hydrostatic drive. Its 37 inches wide. The B2320 standard says it's 45.1 inches wide at the minimum tread. However I think that is with R4 industrial tires. I think the AG tires on a starndard B2320 mine bring the width down to about 43 inches from what I can tell. Anyone out there that has a B2320 could you go out and measure it to see how narrow you think it would go front and rear??? hahahah.......Thanks very much......I'm leaning to the narrow for the position control....going to be just a garden tiller flat land tractor.
