Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Need the model number of the mower. Troybilt XT does not identify the unit. Push mower or rider? Transmission should not be attached to the engine,???
Kohler makes many models, the engine is not identified in the mower model. Model number should be on the engine cover! If you tightened the lower section of the engine, it is very possible that the engine is binding! You may have thrust washer inside engine, that is now out of place!
Here is XT 173.
Try loosing the bolts, turn engine until it feels free, then re-tighten the bolts.
