Got this from a buddie of mine who gave up on it Ser# 13wx78ks011 BRONCO he changed both the drive belts now it only runs Half speed 2.5 MHP instead of the 5.5 posted speed it should run. I am about to pull my hair out try to figure this thing out. Any help out there.
Thanks

I ran into a few threads about this subject while researching my own issue. I believe that on yours there are 2 belts that connect to the variable speed pulley system.
There were a few responses that I saw...too loose, broken/stretched belt, too tight... etc.
Ultimately, it comes down to one of the belts failing to adequately grab the pulley and move the tractor. The fixes were:
Adjust/repair tensioner.
Replace belt.
Replace bad pulley
If you have to push the drive pedal in fairly far before it starts to move the tractor, then the belt(s) are likely too loose and need tightening.
Hope that at least points you towards a possible fix.
