Common Reasons for Ferris Error Codes
1. Operator Safety Switch Failures
Seat, brake, or PTO safety switches often trigger codes due to wear or poor connection.
2. Battery & Charging Issues
Corrosion, bad ground connections, or faulty alternators can cause low voltage errors.
3. Oil & Temperature Problems
Low oil levels or dirty oil filters are frequent causes of pressure and temperature-related codes.
4. Engine Sensor Failures
Modern EFI and electronic throttle control systems are sensitive to faulty sensors or misalignment.
5. Wiring Harness Damage
Rodents, weathering, or mechanical wear can cause shorts and open circuits.

How many hours is too much for a zero-turn mower?
A zero-turn mower is considered to have “high hours” at:
- 1,000+ hours for residential models
- 2,500+ hours for commercial models
However, this doesn’t mean it’s useless, well-maintained machines can keep running well past that. But parts like spindles, hydro drives, and engine components may require replacement or overhaul.
What is the top speed of the Ferris zero turn?
The top speed of Ferris zero-turn mowers varies by model:
