⭐ Key Features & Benefits
💪
Forged C45 Steel
High-carbon steel with controlled forging for superior grain structure and fatigue resistance under cyclic loading.
⚙️
Precision CNC Machining
Triangular bore CNC-finished to ±0.05 mm tolerance, ensuring a snug fit with zero play on the profile tube.
🔥
Heat-Treated Surface
Induction hardening to 58–62 HRC on bearing surfaces extends service life by up to 3× compared to untreated parts.
🌍
Universal Series Coverage
Available in series 1 through 10 including 7N, 32, 36, and 38 — one supplier for every triangular yoke need.
💧
Corrosion-Resistant Finish
Zinc-plated or black-oxide coating protects against moisture, fertiliser residue, and harsh field conditions.

📚 Selection Guide
Step 1: Measure the triangular tube flat-to-flat dimension (A) to identify the series.
Step 2: Cross-reference A, B, C, D in the spec table.
Step 3: Choose .06 (longer) for heavy-duty or .07 (shorter) for compact spaces.
Step 4: Confirm the yoke mates with your existing cross kit.
🌾 Typical Application Scenarios
🌿 Rotary Mowers & Slashers
Transfers tractor PTO power to mower gearboxes for pasture maintenance.
🌾 Hay Tedders & Rakes
Drives tedder rotors for even hay drying across wide swaths.
💾 Fertiliser Spreaders
Powers spinner discs on broadcast spreaders for uniform nutrient distribution.
⚙️ Post Hole Diggers
Connects PTO output to auger gearbox for fence post drilling.
🛠️ Installation & Usage Guide
Clean the triangular profile tube and yoke bore with degreaser to remove old grease and debris.
Slide the triangular yoke onto the profile tube, aligning the geometry precisely.
Ensure the yoke seats fully — the tube end should be flush with or recessed from the yoke face.
Attach the cross-and-bearing kit to the yoke ears using snap rings or bearing straps.
Grease the universal joint fittings and profile tube with NLGI #2 EP lithium grease.
Reconnect the driveline to the tractor PTO and implement, then perform a low-speed test run.
