Re: Category 0, 3 point back blade 4\'
I have a 4' back blade for my little B7100 that has worked well for me over the years. That said, if I had to do it over again, I would get a 5' blade. The reason is that when the blade is angled, the blade only barely extends beyond the tires. Also, I have to hang suitcase weights on the blade to get it to cut into dirt very well because it is so light.
If your tractor will lift a 5' blade, I would recommend that.
