⚠️ Before You Order – Verify Fitment
This filter kit fits select machines equipped with a Hydro Gear ZT-4400 transmission. Fitment can vary by model and application, so do not order by appearance alone.
Important: This kit is designed for one transmission only. Most dual-hydro zero-turn mowers will require 2 kits for a complete hydro service.
