If you’re here then you probably have a John Deere STX 38 or similar yard tractor. These STX tractors with the black dek are know for having issues. After having persistent problems with the mow deck on my tractor I thought I would post a short video tutorial on how to repair he deck on a John Deere lawn tractor.
In my case the bearing in my idler pulley had play and was allowing the belt to slip off. I’ll be posting more resources such as the parts list and an actual John Deere STX 38 repair manual.
