For owners of Ferris IS2000Z, IS3100Z, or Wright WTZO6149T8E decks, finding a replacement that delivers factory‑level engagement without breaking the bank is a daily headache. The ROP Shop Electric PTO Clutch promises a bolt‑in solution with a billet‑machined pulley and ready‑to‑wire harness, but does it live up to the hype?

Frequently Asked Questions
- Is the clutch compatible with all belt widths? No. It is sized for a 5/8‑inch belt only. Using a different width may cause slippage.
- Do I need to replace the existing pulley? The kit includes a billet‑machined pulley that replaces the OEM unit for optimal torque transfer.
