Triangular Yoke for PTO Shaft
The Triangular Yoke is a precision-engineered PTO shaft end yoke designed for reliable torque transmission via triangular-profile tubes. Crafted from forged C45 steel and induction-hardened for extended wear life, this yoke fits series 1 through 10 (including 7N, 32, 36, and 38 variants) with bores from 22 to 41 mm. Ideal for rotary mowers, hay tedders, spreaders, and post hole diggers across Australian, European, and North American farming operations. Every piece is CNC-machined to ±0.05 mm and supplied with zinc or black-oxide coating for corrosion protection.
Triangular Yoke for PTO Shaft – Heavy-Duty Agricultural Drive Connector
Premium triangular profile yoke | Series 1–10 | 22–41 mm bore | ISO-certified quality
The Ever-power Triangular Yoke connects your implement’s triangular-profile tube to the PTO driveline, transmitting rotational power with minimal vibration. Forged from C45 carbon steel, heat-treated to 58–62 HRC, and precision-machined to tight tolerances, it is the go-to choice for farmers and OEM manufacturers who demand consistent performance season after season.

⭐ 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.
🔄 Compatibility Information
Compatible with all standard triangular-profile PTO tubes used in European and Australian implements. Fits series 1–10 drivelines from Walterscheid, Bondioli & Pavesi, Comer Industries, and Ever-power. Suitable for rotary cutters, hay tedders, spreaders, feed mixers, and more.
📚 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.
