Lemon Yoke for PTO Shaft – Precision Lemon-Profile Driveline Connector
Lemon-shaped profile yoke | Series 1L–36L | 22–36 mm bore | 5-dimension specification
The Ever-power Lemon Yoke features a purpose-designed lemon-shaped bore that mates seamlessly with lemon-profile PTO tubes. Its optimised geometry enables angular misalignment compensation while maintaining a tight, backlash-free connection. Each piece undergoes forging, normalising, CNC machining, and surface treatment for consistent performance across thousands of operating hours.

⭐ Key Features & Benefits
🍋
Lemon-Profile Precision Bore
CNC-profiled to precisely match lemon-shaped tubes, eliminating slop and ensuring efficient power transfer.
🔨
Drop-Forged Alloy Steel
Forged from 42CrMo alloy steel for exceptional toughness and impact resistance.
🛠️
Extended Dimensional Range
Five dimensions (A–E) per series ensure exact fitment with no guesswork.
⚡
Low Rotational Inertia
Optimised wall thickness reduces mass for quicker PTO engagement and lower fuel consumption.
💫
Long Service Intervals
Hardened bearing surfaces and phosphate coating extend service intervals to 500+ hours.
🔄 Compatibility Information
Designed for lemon-profile PTO tubes across European-standard drivelines. Compatible with Comer, Walterscheid, Bondioli & Pavesi, Benzi & Di Terlizzi, and Ever-power. Ideal for rotary tillers, power harrows, feed mixers, manure spreaders, and vineyard equipment.
📚 Selection Guide
Step 1: Measure the lemon tube minor axis (A) and major axis (B).
Step 2: Match to the series table; the ‘L’ suffix denotes lemon profile.
Step 3: Choose .06L for heavy-duty or .07L for compact installations.
Step 4: Verify cross kit compatibility by checking yoke ear bore and spacing (C).
🌾 Typical Application Scenarios
🌿 Rotary Tillers & Power Harrows
Drives soil cultivation implements demanding constant, vibration-free torque.
🐄 Feed Mixers & TMR Wagons
Powers mixing augers where smooth engagement protects gearbox internals.
🌾 Manure Spreaders
Connects to beater shafts and spinner mechanisms for fertiliser distribution.
🍇 Vineyard & Orchard Equipment
Compact variants fit narrow-row machinery for pruning and mulching.
🛠️ Installation & Usage Guide
Inspect the lemon-profile tube for deformation or excessive wear before fitting.
Apply anti-seize compound to the tube surface to prevent fretting corrosion.
Align the yoke bore with the tube profile and slide on firmly until seated.
Install the universal joint cross kit; secure with snap rings or U-bolt straps.
Pump NLGI #2 EP grease through the cross kit zerks until fresh grease appears at all seals.
Check that the yoke slides axially with no radial play, then reconnect and test at low RPM.
