I guess on a rake I'd probably go with the 6 footer....... rear blade definitely a 5 footer. I run a 6 foot LandPride rake on my cabbed B3030 with loaded tires, and the 6 foot rake will stop my tractor dead when there is enough debris in the rake.
I have a B 2620 and a 5' Woods rake. I can angle the rake and still cover my tracks. I purchased the rake for use with my BX 2200. If I were to purchase one for the 2620, I would buy a 6' rake, but it is not important emough for me to trade.
