Cat 1 Quick Hitch Lower Link Hooks – No Weld Easy Change Kit – SPH430525

Key Features & Benefits

• No welding or cutting: Fits directly onto compatible tractor lower lift arms using the supplied bolt-on mounting components.
• Quick implement changes: Makes attaching compatible ploughs, cultivators, harrows, seeders and other Cat 1 implements easier and more convenient.
• Spring-loaded locking hooks: The spring-loaded latch mechanism helps retain the implement connection pin inside the hook.
• Open-position latch: The latch can be held open when required during implement handling.
• Pre-assembled mounting hardware: Both hook bodies are supplied with the necessary bolts, nuts, pins and U-bolts already fitted.
• Adjustable stabilizer bar: Connects the two hook assemblies and helps maintain the correct lower arm spacing when approaching an implement.
• Alignment shims included: Supplied adjustment plates allow the hook assemblies to be positioned parallel to the tractor lift arms.
• Removable and reusable: The bolt-on construction allows removal and installation on another compatible tractor.

Important Dimensions – Check Before Ordering

For correct installation, check both the height and thickness of your tractor's lower lift arms. The hook body must fit over the lift arm with sufficient room for the mounting and adjustment components.

How Does the Quick Hitch System Work?

The SPH430525 replaces the conventional lower link connection procedure with two hook-type coupling points mounted directly onto the tractor's existing lift arms.

Carefully reverse the tractor towards the implement, position the hooks under the compatible lower attachment pins, and slowly raise the three-point linkage.

Once the implement pins are correctly seated, verify that both spring-loaded latches are securely engaged before operating the equipment.

The tractor's upper link and any required PTO shaft must still be connected separately.

Easy No-Weld Installation

1. Prepare the hooks: Remove the main mounting pins and loosen the adjustment screws and locknuts.
2. Position the assemblies: Slide each quick hitch body over the corresponding tractor lower lift arm.
3. Check alignment: Determine whether the 6 mm (0.24") or 10 mm (0.39") adjustment plates are needed to keep the hook parallel to the arm.
4. Secure the plates: Fix the selected plates using the Ø10 mm (0.39") retaining pins and position them inside the hook body.
5. Fit the main mounting hardware: Install and secure the main pins and U-bolt components according to the supplied instructions.
6. Final adjustment: Align the two hook assemblies, then tighten the adjustment screws, locknuts and U-bolt nuts securely.

Always follow the supplied installation instructions and check all fasteners, retaining pins and latches before use.
