Will not move in lower gears. Only in 5th and 6th.
Lawn tractor would stop pulling in lower gears after about 3 minutes of use. Changed drive belts. Still same problem accrued. So I decided to replace the variable speed double pulley. Put it back together and problem solved.
Check drive belts for wear first. Then to replace pulley take the short spring on bracket that goes to right side of middle chassis. That looses belt to slip off of pulley. Then take center bolt that holds pulley on bearing Assembly off. Then pull up on pulley to slide off and remove. Then repeat steps from last to first. No problem easy repair
