My question is this, if I'm running at half rpm, is the belt spinning the trans at half rpm
|
.
Yes, the pulleys are usually 1:1 ratio for modern small hydros, and occasionally the trans runs slower than the engine in some models.

When I put the brake on and get off, I can see the belt is not moving. So I'm assuming that when brake is applied it takes the tension off
|
.
Yes the brake releases tension from the belt. It's a safety item because the hydro can overpower the brake if something were to go wrong. But the big issue with that is when the hydro pulley is not spinning, neither is the fan to cool it, which isn't an ideal situation.

I don't think I need to run wot to pull a yard cart around. When I slow to a stop is the belt still running the trans but since I'm not pressing the foot pedal it's just doing no "work"?

Yes the belt is still running the trans. If you have a heavy load, it is more efficient and better for the trans to run it at full throttle. An empty cart can be towed at less than full throttle.
You most likely have a Tuff Torq K46 transaxle and it will last beyond 250 hours if you change the oil at least once with 5W-50 synthetic oil between 50-100 hours.
