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

Tractor drive variable pulley separated at welded points. No possible repair of part.
1. Remove mower deck, to gain access to drive pulleys and belts.
2. Remove springs from drive systems, always use a "spring puller".
3. Remove battery and tray ( MTD) brands have that in the bay where the drive resides.
4. Elevate tractor to reach drive pulley "bolt" that holds down pulley system.
5. Lift outward drive pulley, somewhat a challenge to work this outward.
6. Re-install new drive pulley system. Use vice grip pliers to hold pulley from spinning
7. Re-install drive belts and final drive pulley belt." Make sure your belts are within the guides" --otherwise this will break the belts. Had one that did that, and almost made a fatal error.
8. Re-install battery and tray system
9. Re-install mower deck when unit is down, most difficult to return all pins and and springs.
10 Adjust drive linkage and button up access panels. New drive works and moves as new -- again.

  • Replacement part perfect fit. Thanks for keeping in stock.
    Description diagram on web site, shows part scaled larger than the part needed for replacement. This made my ordering somewhat a guess, but on arrival, the part was manufactured exactly for this tractor. Very happy for the ease of installation, not so easy to re-install mower deck
