Description
Lemon Yoke for PTO Shaft — Precision Lemon-Profile Connection for Power Take-Off Drive Lines
The Lemon Yoke for PTO Shaft is specifically designed for lemon-profile (oval-lemon) PTO tubes, one of the most common tube shapes in European-standard agricultural drive lines. The distinctive lemon bore geometry provides a positive-lock fit that prevents rotation on the tube while allowing smooth telescoping action for shaft length adjustment. Each yoke is precision-forged and CNC-machined to exacting tolerances, with induction-hardened bearing bores and corrosion-resistant surface treatment. Available in a comprehensive range of series sizes from 1.06L to 36.07L.

⭐ Key Features & Benefits
🍋 Lemon-Profile Bore Geometry
Precision-machined lemon-shaped bore ensures exact fit on standard lemon PTO tubes, preventing rotation while permitting smooth axial sliding.
💪 Drop-Forged Steel Body
Hot-forged from 40Cr alloy steel for exceptional strength-to-weight ratio and resistance to shock loading.
🔥 Dual-Dimension Design (D & E)
Each series includes both D and E dimensions, allowing selection based on cross kit size and clearance requirements.
⚖ Wide Series Range
Covering Series 1L through 36L with 18 standard variants for light, medium, and heavy-duty PTO systems.
🛡 Protective Surface Coating
Available with zinc plating, phosphate coating, or black oxide finish for enhanced corrosion resistance.
✅ OEM-Grade Dimensional Accuracy
CNC machining delivers bearing bore tolerances within ±0.015 mm, meeting or exceeding OEM standards.
🔄 Compatibility Information
Compatible with all standard lemon-profile PTO tubes in Series 1 through 36. Fits PTO shafts from Walterscheid, Bondioli & Pavesi, Comer Industries, Benzi & Di Terlizzi, Magdalena. Works with tractors from John Deere, New Holland, Massey Ferguson, Kubota, Case IH, CLAAS, SAME Deutz-Fahr, McCormick. Integrates with standard cross kits, safety shields, and torque limiters.
📚 Selection Guide
Step 1 — Confirm Lemon Profile: Verify your PTO tube has a lemon (oval) cross-section. Measure the B (outer width) dimension.
Step 2 — Select the L-Series: Match the B dimension to the table. The L suffix denotes lemon profile.
Step 3 — Verify D & E Dimensions: D corresponds to cross kit journal span; E is overall width. Choose based on your cross kit.
🌾 Typical Application Scenarios
Disc mowers, drum mowers, tedders, rotary rakes, round and square balers
Feed mixers, TMR wagons, silage distributors, grain mills
Rotary cultivators, power harrows, stone crushers, forestry mulchers
Sprayers, fertilizer spreaders, seed drills, vineyard equipment
🛠 Installation & Usage Guide
- Verify tube profile: Confirm the PTO tube is lemon profile. A lemon yoke on a triangular tube will cause damage.
- Clean mating surfaces: Remove dirt, rust, old grease from both bore and tube exterior.
- Slide yoke onto tube: Align the lemon profile and push. Should slide smoothly with minimal play.
- Install cross kit bearings: Press bearing caps into bores and secure with snap rings or straps.
- Apply grease: Lubricate cross kit fittings and apply thin grease inside lemon bore for smooth telescoping.
- Safety check: Ensure safety shield is installed and all retaining hardware is secure.
