What do the letters mean?

[AUmower]

Just got my new Husqvarna GTH 24V52LS tractor. Love it...mows great and runs like a champ. Cut the mowing time for my 3 acres by 30 mins over my Toro Z-Master.

But, I am curious, can anyone tell me what some of these cryptic letters mean?
Why GTH and not just GT? What is the 24V and where did the X go compared to some of the others with XLS?

I know it won't make a difference in how it mows, but maybe I can get some sleep at night instead of wondering what they all mean.

Thanks
