Description
Splined Yoke 11 (Push Pin) — Heavy-Duty Extended-Series PTO Yoke for High-Horsepower Applications
The Splined Yoke 11-Push Pin fills a critical gap in the PTO yoke market: push pin convenience for heavy-duty applications above 100 HP. While many push pin yokes top out at Series 8, the Type 11 extends all the way to Series 50 with a 50 mm bearing bore, accommodating the largest cross kits and highest-torque PTO drive lines in existence. Five spline bore configurations per series ensure compatibility with every PTO speed and standard used on heavy tractors and industrial PTO-driven equipment.

⭐ Key Features & Benefits
💪 Series 6-50 Heavy-Duty Range
The only push pin yoke extending to Series 50 (50 mm bore, 118 mm tube OD) for the largest PTO systems.
⚙ Five Spline Configurations
B (Z6), D (Z21), G (8-32), C (1 3/4″ Z6), E (1 3/4″ Z20) — full coverage of every international PTO standard.
🔒 Push Pin at Scale
Brings the convenience of hand-operated quick-release to applications previously limited to bolt retention.
🔥 Reinforced Pin Mechanism
Heavy-duty spring and oversized pin designed for the higher inertial forces encountered in large-diameter PTO shafts.
📐 300+ HP Capability
Series 42 and 50 yokes are rated for tractors exceeding 300 HP when paired with appropriate cross kits.
🛡 Industrial-Grade Construction
Heavier forging with additional material in high-stress areas for reliability in continuous industrial operation.
🔄 Compatibility Information
Covers all PTO spline standards from standard 1 3/8″ through heavy-duty 1 3/4″. For high-HP tractors: John Deere 7R/8R/9R, Case IH Magnum/Steiger, New Holland T7/T8/T9, Fendt 900/1000, CLAAS Xerion, Massey Ferguson 8S/9S. Also for industrial PTO-driven equipment from Doppstadt, Komptech, Vermeer, Bandit.
📚 Selection Guide
Step 1 — Determine Required Torque Capacity: For 100-200 HP, Series 6-8 is usually sufficient. For 200-300+ HP, Series 10-50 is recommended.
Step 2 — Match PTO Output Size: Measure the tractor PTO stub diameter and count splines. Heavy tractors typically use 1 3/4″ splines (C or E variant).
Step 3 — Verify Push Pin Suitability: For extreme shock-load applications (rock crushers, stump grinders), bolt retention may be preferred despite push pin convenience.
🌾 Typical Application Scenarios
Big square balers, self-propelled forage harvesters, large combine header drives
Wood chippers, horizontal grinders, stump grinders, biomass processors
Large-bore slurry pumps, flood water pumps, industrial transfer pumps
PTO-driven hydraulic power packs, mobile crushers, screening equipment
🛠 Installation & Usage Guide
- Use appropriate handling: Series 42 and 50 yokes are heavy — use proper lifting techniques or mechanical assistance.
- Align and engage splines: With larger splines, precise initial alignment is important. Rotate the yoke slightly to find engagement.
- Verify push pin seats fully: The heavy-duty pin must click firmly into the groove. Do not operate if pin is not fully engaged.
- Use heavy-duty cross kits: Pair with cross kits rated for the application HP — under-rated cross kits are a common failure point.
- Comprehensive lubrication: Heavy-duty applications demand more frequent and thorough greasing.
- Regular inspection: Check push pin, spline wear, and bearing condition every 20 operating hours for heavy-duty applications.
