Lemon Yoke for PTO Shaft

The Lemon Yoke (lemon-profile yoke) is a critical PTO driveline component engineered for lemon-shaped profile tubes. Featuring a rounded elliptical bore geometry, it delivers smooth torque transfer while accommodating controlled angular displacement. Available across series 1L to 36L with bores from 22 to 36 mm and five key dimensions (A–E), it suits rotary tillers, feed mixers, and manure spreaders. Manufactured from forged 42CrMo alloy steel with precision CNC machining and phosphate coating, it meets ISO standards and ships globally.

Lemon-shaped profile yoke | Series 1L–36L | 22–36 mm bore | 5-dimension specification

Lemon yoke for PTO shaft

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

1

Inspect the lemon-profile tube for deformation or excessive wear before fitting.

2

Apply anti-seize compound to the tube surface to prevent fretting corrosion.

3

Align the yoke bore with the tube profile and slide on firmly until seated.

4

Install the universal joint cross kit; secure with snap rings or U-bolt straps.

5

Pump NLGI #2 EP grease through the cross kit zerks until fresh grease appears at all seals.

6

Check that the yoke slides axially with no radial play, then reconnect and test at low RPM.

❓ Frequently Asked Questions

▶ What distinguishes a lemon yoke from a triangular yoke?
The lemon yoke has an elliptical bore; the triangular has a three-sided bore. They are not interchangeable.
▶ Can I retrofit a lemon yoke onto a star tube?
No — profiles must match exactly. Mismatched profiles cause vibration and premature failure.
▶ What does the ‘L’ suffix mean?
It denotes lemon profile. E.g. 5.06L is a Series 5 lemon yoke with the .06 (long) variant.
▶ How often should I inspect?
Visually every 50 operating hours for cracks or scoring. Replace immediately if cracked.
▶ Do you supply matching lemon tubes?
Yes — we manufacture complete lemon tubes and can supply paired kits.
▶ What is your MOQ for OEM?
Standard MOQ is 100 pieces per series; smaller pilot batches are negotiable.
