You can get that model # elsewhere but Im not sure if it always includes the pigtail that is required for the Husvarna charging port.
Funny thing is it doesnt look very different from the Sears Diehard Platinum tender I bought...I wonder if you could pick up any of the lookalikes and just find the correct pigtail attachment elsewhere.
Husqvarna now makes sears garden tractors and the yt series tractors. The other models sears sells are made by mtd. So it would make sense if the charger looks a lot like it since it was probably made by husqvarna.
