I did it so it would have the same type of alt. as my bx and I plan to add lights to it. My experience has been a true alt is a lot easier on your battery too. I found this alt. cheaper than what that dynameter cost from Kubota if I had to buy a replacement. This is not a just a lawnmower. Show...
My BX1880 actually came with the larger BX series R14 Goodyears on it, which was a plus because if it had the stock tires, I wanted to upgrade it to the larger rims and tires from the other BX series.
