I have a Kubota B2150 with turf tires and a 60" rear blower mounted on it. I've added front weight to even out the weight distribution. My gravel driveway is mostly flat but has one short, steep hill in it. I'm considering getting chains for it. Would standard ladder chains work ok or should I consider something more aggressive? I'm assuming it would be better to use them on the rear wheels rather than the front? Thanks.
