I have searched the forums, and have found where many opt for an upgraded alternator on the B2920. Does anyone have an idea on the part number, or how much it costs to have it installed?

The kit is available through whole goods (sales dept.) and is # B7311. List price on it is $186. Not sure how much the dealer would charge to install it, should be easy to do your self though.

I'm curious. What is the amp rating of your OE alternator vs the Upgraded one?

I am not sure haha. I am getting a new tractor and was thinking of adding lights.

Why not just mount the new lights and monitor your battery voltage before and after you use tractor to determine if it's even necessary....

This is a new tractor, right..??....Maybe the tractor dealer could upgrade before you take delivery?

I believe it's 30 amp,,,,the optional one is 40,,considering that you are only USEING the battery for starter and glow plugs and not for spark, ,,,30 amp should power a couple of extra lights,,,I have the rear light and two on the rops,,,on mine and it's fine,,,,If I had to buy it again, I would spec it out with 2 spool valve on the back (3 rd function) ,,not a bigger alternator

Thanks for the tips and info. After reading these, I think I will be fine with the stock option. I also read that the dipstick and stuff have to be altered with the upgrade, which is fine, but if I don't need it then I will skip it :thumbsup:
