Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
Does the transmission drive belt on top of the transmission quit turning. or does it keep turning. If belt keeps turning,problem has to be the transmission.
Transmission is not serviceable, but the # 15 ,is plug that can b removed, and yu can add a small amount of 15W50 engine oil, maybe a cup full, to see if it helps!
If the tractor rolls free, showing the brakes are not dragging, it has to be transmission!
