Description
Triangular Yoke for PTO Shaft — Premium Implement Connection for Agricultural Drive Lines
The Triangular Yoke for PTO Shaft is an essential power take-off drive shaft component engineered for reliable torque transmission between tractors and implements. Designed with a precisely machined triangular bore profile, this yoke provides a secure, anti-rotation fit onto triangular PTO tubes — eliminating slippage and ensuring consistent power delivery even under heavy loads. Manufactured from premium forged steel with precision CNC machining, each yoke undergoes rigorous heat treatment and surface finishing to ensure optimal hardness, wear resistance, and extended service life across demanding agricultural environments.

⭐ Key Features & Benefits
⚙ Precision Triangular Bore
CNC-machined triangular profile ensures a tight, slip-free fit on standard triangle tubes, delivering maximum torque without rotational play.
💪 Forged Alloy Steel Construction
Hot-forged from high-carbon alloy steel, providing superior tensile strength and impact resistance for the most demanding field conditions.
🔥 Induction Hardened Bearing Areas
Critical bearing surfaces are induction hardened to HRC 58-62, dramatically extending service life and reducing wear from repetitive loading.
📐 Complete Series Coverage
Available across Series 1 through Series 10 (including 7N, 32, 36, 38 variants), covering virtually every standard PTO application.
🛡 Anti-Corrosion Surface Treatment
Zinc-plated or black oxide finish provides long-term corrosion protection in humid, dusty, or chemically exposed agricultural environments.
✅ Direct OEM Replacement
Dimensions and tolerances match or exceed OEM specifications for Walterscheid, Bondioli, Comer, and other leading brands.
🔄 Compatibility Information
This triangular yoke is compatible with all standard triangular-profile PTO tubes across Series 1 through Series 10. It fits PTO shafts from major manufacturers including Walterscheid, Bondioli & Pavesi, Comer Industries, Agriest, and Benzi & Di Terlizzi. Suitable for tractors from John Deere, Massey Ferguson, New Holland, Kubota, Case IH, CLAAS, Fendt, Deutz-Fahr, and most other European and North American tractor brands. The yoke integrates seamlessly with standard cross kits (universal joints) and safety shield assemblies.
📚 Selection Guide
Step 1 — Identify Your PTO Series: Measure the outside dimension (B) of your triangular tube. Series 1 tubes measure approximately 54 mm, while Series 10 tubes measure 118 mm.
Step 2 — Choose .06 or .07 Variant: The .06 suffix indicates a wider yoke (larger D dimension) suited for heavy-duty applications. The .07 variant is more compact for lighter implements.
Step 3 — Match Cross Kit Size: Ensure the yoke bearing bore (A dimension) aligns with your universal joint cross bearing cap diameter. Common sizes: 22, 27, 30.2, 35, and 41 mm.
🌾 Typical Application Scenarios
Rotary mowers, disc mowers, tedders, rakes, round balers, square balers
Rotary tillers, power harrows, mulchers, stone buriers, flail mowers
Water pumps, slurry mixers, manure spreaders, liquid fertilizer applicators
Seed drills, planters, fertilizer spreaders, grain augers
🛠 Installation & Usage Guide
- Inspect components: Check the yoke bore, cross kit bearings, and PTO tube for damage or excessive wear before assembly.
- Align yoke with tube: Slide the triangular yoke onto the matching triangular tube, ensuring profile alignment.
- Secure with retaining method: Use the appropriate snap ring, retaining bolt, or weld-on method to lock the yoke.
- Install cross kit: Insert the universal joint cross into the yoke bearing bores and secure with snap rings.
- Grease all fittings: Apply EP2 lithium grease to cross kit zerks and lubrication points.
- Check operating angle: Ensure PTO shaft angle does not exceed 25° for standard joints.
