PTO Shaft Structure & Function on the Peanut Harvester
The power take-off (PTO) shaft is positioned between the rear of the tractor and the front input of the peanut harvester. It is a two-piece telescoping assembly connected by universal joints at each end. The tractor-end yoke mates with the PTO stub shaft, while the implement-end yoke connects to the peanut harvester’s gearbox input.
When engaged, rotational power flows from the tractor’s engine through the PTO gearbox, out the stub, through the first U-joint, along the profile tube, through the second U-joint, and into the implement. During groundnut lifting and collection, this power drives the cutting, turning, or processing mechanism of the peanut harvester.
Key structural components include: hardened splined yokes for positive engagement, needle-bearing U-joint crosses for smooth rotation under load, telescoping tubes for length adjustment, plastic safety shields with bearing-supported rotation, and an overload clutch or shear pin to protect the entire driveline from catastrophic failure.
Core Advantages of Our PTO Shaft for Peanut Harvester
⚙ Forged Yoke Technology
Unlike stamped alternatives, our forged yokes for the peanut harvester PTO shaft deliver superior grain structure and impact resistance for demanding applications.
🔧 Wide-Angle Joint Option
Wide-angle constant-velocity joints available for applications requiring operating angles up to 80°, ideal for tight turning radii and steep terrain.
🔒 Automatic Re-engagement
Friction clutch models automatically re-engage once the overload condition clears, minimising downtime and getting you back to work faster.
⚖ Anti-Corrosion Finish
Zinc-plated hardware and powder-coated guards resist corrosion from agricultural chemicals, moisture, and UV exposure.
🛠 Metric & Imperial Compatibility
Dual-standard spline options ensure compatibility with both metric and imperial PTO stubs across all major tractor brands.
🏆 Global Quality Certification
ISO 9001:2015 certified manufacturing with full material traceability from raw steel to finished product.

Targeted Installation Procedure – Peanut Harvester PTO Shaft
⚠ Safety First: Disengage the PTO, switch off the engine, remove the ignition key, and allow all moving parts to come to a complete stop before working on the driveline. Wear appropriate PPE including close-fitting clothing and gloves.
Phase 1: Preparation
Lay out all shaft components and cross-reference against the packing list. Confirm the shaft series, closed length, and yoke specifications match your peanut harvester setup. Grease all U-joint nipples and slide the profile tubes back and forth several times to distribute lubricant.
Phase 2: Length Verification
With the peanut harvester hitched to the tractor in its normal operating position, measure the PTO-to-input distance. The shaft must have a minimum of 1/3 tube overlap at full extension and must not bottom out at the shortest position. Trim the tubes if the factory length requires adjustment (refer to cutting instructions in the product manual).
Phase 3: Tractor Connection
Push the tractor-end yoke fully onto the PTO stub. The quick-release collar should snap over the retaining groove. Pull back on the yoke to confirm it is locked. If using a plain-bore yoke, insert the shear pin and secure with a cotter pin.
Phase 4: Implement Connection
Connect the implement-end yoke to the peanut harvester’s input. If a clutch assembly is fitted at this end, ensure the clutch housing is oriented with the grease nipple accessible. Tighten any set screws to the specified torque.
Phase 5: Guard Fitting
Assemble the two guard halves around the shaft and clip together. Attach the anti-rotation chains: one chain to a stationary tractor point, one chain to the implement frame. Verify the guards spin freely by hand without contacting any part of the shaft or yokes.
Phase 6: Operational Test
Start the tractor, engage PTO at low idle, and run the peanut harvester unloaded for two to three minutes. Check for vibration, abnormal noise, or heat at the U-joints. If all checks pass, proceed to normal operating speed and begin field work. Re-torque all fasteners after the initial run-in period.

Frequently Asked Questions – PTO Shaft for Peanut Harvester
❓ Do you ship to regional and remote Australia?
Absolutely. We ship to all Australian postcodes via major freight carriers. Regional and remote areas may have slightly longer transit times, but we work with multiple carriers to ensure reliable delivery across the country.
❓ Can the shaft be shortened to fit my setup?
Yes. The telescoping profile tubes can be cut to a shorter length using an angle grinder or chop saw. Ensure a minimum of 1/3 overlap remains between the inner and outer tubes after cutting. Deburr all cut edges before reassembly.
❓ Will this shaft fit my tractor and peanut harvester?
Our PTO shafts are available with all standard yoke types and spline sizes (1-3/8" 6-spline, 1-3/4" 6-spline, 1-3/4" 20-spline, and more). Provide your tractor model and peanut harvester make/model, and our team will confirm compatibility before dispatch.
❓ How do I measure the correct closed length?
Hitch the implement to the tractor in its normal working position. Measure the straight-line distance from the face of the tractor PTO stub to the face of the implement input shaft. The shaft closed length should be approximately 10–15 mm less than this measurement.
❓ Chế độ bảo hành của quý công ty đối với trục PTO là gì?
Tất cả các trục PTO đều được bảo hành của nhà sản xuất đối với các lỗi về vật liệu và tay nghề. Điều khoản bảo hành khác nhau tùy theo dòng sản phẩm. Vui lòng liên hệ với đội ngũ của chúng tôi để biết chi tiết bảo hành cụ thể áp dụng cho sản phẩm bạn đã mua.
❓ What PTO shaft series do I need for my peanut harvester?
For most peanut harvester applications in the 60–180 HP range, we recommend the T4 / L4 (Medium-heavy duty) or T5 / L5 (Heavy duty) series. If you operate near the upper end of this range or in particularly demanding conditions, consider stepping up to the S8 (Wide-angle) series for additional safety margin.
❓ Tôi nên bôi trơn trục PTO bao lâu một lần?
Bôi trơn tất cả các đầu nối chữ U sau mỗi 8-10 giờ hoạt động, hoặc vào đầu mỗi ngày làm việc. Bôi trơn các ống định hình dạng ống lồng với cùng khoảng thời gian đó. Sử dụng mỡ phức hợp lithium EP2 hoặc theo khuyến cáo trong sách hướng dẫn sử dụng sản phẩm.
❓ Sự khác biệt giữa bu lông cắt và khớp ly hợp ma sát là gì?
Bu lông cắt là một loại chốt hy sinh, tự gãy khi mô-men xoắn vượt quá khả năng chịu tải định mức. Nó có giá thành thấp nhưng cần được thay thế thủ công sau mỗi lần sử dụng. Ly hợp ma sát sẽ trượt khi quá tải và tự động khớp lại khi tình trạng quá tải chấm dứt, giúp vận hành liên tục trong các ứng dụng thường xuyên chịu tải trọng va đập.
