Hello guys, I'm trying to figure out if I have the higher capacity alternator, or the cheaper dynamo on my B2620. I can hear a whirring sound on occasion and believe is the dynamo, or alternator, charging the battery. Can someone tell me what to look for to help determine which this unit has? Pics would be great.

My B came with the dyno and unless you paid to have the alt added that is probably what you have. I only run two LED lights for plowing and the dyno is enough to keep the battery full. Of course I use a trickle charge in between uses.

As far as I know the HD Altenator is an option. When I bought my B7610 in 2007, I also bought the higher capacity alternator and had it installed. Far as I know, the old one is still sitting on a shelf in the barn. I wouldn't think Kubota would use a dynamo as they are typically less reliable than the alternator.

My 2012 B2620 has a Dyno as the OE and it performs well in my usage. Two halogen lamps that are ROPS mounted draw 9 amps and the battery holds up to my satisfaction. So far, I've had no problems.
