So I just had my L2501DT delivered and am looking at box blades. I've read every thread I can find in trying to decide between a 5' and 6' box blade. I think a 66" would be ideal based on the tractor with R1's being 66" but trying to find a 66" is proving challenging. So here is a poll to let me know what size you are using on your L2501 or L2502. Maybe it will help me decide.
