Dead in Tracks - Cub Cadet 50" / BS 22HP

[Bhill_62]

I have a 2005 Cub Cadet 50" / BS 22HP Zero turn. I was mowing along last week and slowly I started to lose speed. Engine was running fine. Eventually I came to a complete stop. Both drives stopped functioning at exactly the same time. Hydraulic Fluid is good. I assume it's a pump but would like a experts opinion and direction. Thanks!

I would start by checking the condition of the pump drive belt. It could be worn out, and slipping, and maybe eventually broke.
