After using my 3320 for a few small tasks today, during which braking was normal, I attached a bush hog, which uses a single hydraulic to change the deck height. Sometime at or after attaching the bush hog, the brakes becamse seized. After mowing for a while, I realized the tractor would not roll in neutral and then I noticed the smoke coming from both sides of the tractor at about where the bleeder screws are. I was using a low gear, and never needed the brakes while mowing, and hadn't realized the extra effort the tractor exerted during that time. Also, the brake pedals don't push in at all.
I would be grateful for help diagnosing the problem.
