Possible causes for the cutter heads failing to keep turning on a Jacobsen Greens King IV include:

1. Reel levers not properly engaged (they must be out of the backlap position).
2. Hydraulic system issues, such as insufficient pressure or fluid.
3. Worn or damaged reel or bedknife components.
4. Improper adjustment between the reel and bedknife.
5. Electrical or control system faults preventing operation.

Proper maintenance and following the operator's manual are necessary to ensure correct function.
