I have a cub cadet rider with 27hp kohler motor. After mowing

Customer Question

I have a cub cadet rider with 27hp kohler motor. After mowing for a while the tractor seems to cut in and out and start shaking and smoking really bad. If you shut it off and leave it a while you can come back and fire it up and keep mowing with out a problem. It may happen again it may not. Any ideas

Have you ran a spark test when the engine starts shaking? You may have a coil/ignition module cutting out, making the cylinder misfire.

It may be one coil that becomes erratic, not uncommon on a Kohler, and Kohler recommends replacing both coils, if one shows bad.
