Splined Yoke 05 Push Pin — Precision PTO Connection for Agricultural and Industrial Machinery

Engineered for dependable torque transmission across 11 dimensional series, the Splined Yoke 05 Push Pin delivers rapid coupling and release on PTO drive shafts used throughout the United Kingdom farming and manufacturing sectors.

Why the Splined Yoke 05 Push Pin Matters for Your PTO Drive Shaft

Across dairy farms in Somerset, grain operations in East Anglia, and processing plants near Birmingham, reliable power take-off coupling is not a luxury but a daily necessity. The Splined Yoke 05 Push Pin is a critical interface component that bridges the tractor PTO output and the implement input shaft, transferring rotational energy through a precision-machined spline profile while allowing tool-free engagement and disengagement via its integrated push pin mechanism. Unlike threaded or bolted yoke designs, this push pin configuration reduces connection time to just seconds, which translates directly into reduced downtime during seasonal peaks when every hour of uptime counts. Manufactured from high-grade alloy steel and finished to exacting tolerances, each splined yoke undergoes hardness testing and dimensional verification before leaving the production line. Whether you are running a muck spreader in Yorkshire or a rotary tiller in the Welsh Borders, the Splined Yoke 05 Push Pin offers consistent, repeatable engagement across thousands of coupling cycles.

Key Advantages of the Splined Yoke 05 Push Pin Design

Engineering Principle and Material Composition

The operating principle of the splined yoke push pin relies on involute spline geometry to transmit torque between two rotating shafts while permitting limited axial sliding. The external splines on the yoke mate with internal splines on the PTO stub shaft; the push pin then passes through a radial hole in the yoke body and seats in a circumferential groove machined into the shaft, locking the two components axially. When the operator presses the pin head inward against its return spring, the yoke slides freely off the shaft for disconnection. The forging blank begins as rolled bar stock of 42CrMo4 alloy steel, chosen for its excellent fatigue resistance and hardenability. After closed-die forging, the spline teeth are broached in a single pass on a horizontal broaching machine, followed by induction hardening of the tooth flanks to 58–62 HRC. The push pin bore is drilled and reamed to H7 tolerance, and the pin itself is manufactured from case-hardened 20CrMnTi steel with a zinc-nickel surface coating to resist corrosion in the damp British climate. A phosphate pre-treatment beneath the coating further improves adhesion and salt-spray performance, ensuring each splined yoke maintains smooth pin action even after prolonged outdoor storage.

Performance Summary

Application Scenarios Across UK Industries

The Splined Yoke 05 Push Pin finds daily use in a broad range of PTO-driven equipment throughout Britain. On arable farms in Lincolnshire and Cambridgeshire, it couples rotary cultivators and seed drills to tractor PTO outputs running at 540 or 1000 rpm. Livestock operations in Devon and Cumbria rely on the same yoke to connect slurry tankers, feed mixers, and round balers during silage season. Beyond agriculture, the splined yoke push pin is equally at home in light industrial settings: municipal councils across the Midlands fit them to roadside flail mowers and gritting machines, while forestry contractors in the Scottish Highlands use them on PTO-powered log splitters and chippers. The push pin mechanism is especially valued in applications where implements must be swapped multiple times per day, because the connection and release cycle takes only a few seconds without tools. Each of the 11 dimensional series allows procurement managers to standardise on a single splined yoke family rather than sourcing bespoke parts for every machine in their fleet.

Customer Success: Fenland Grains Ltd, Cambridgeshire

Fenland Grains Ltd operates 2,400 acres of combinable crops near Wisbech in Cambridgeshire. During the 2025 drilling season, their workshop manager identified excessive wear on the existing push pin yokes fitted to three Kuhn power harrows. Yoke replacement was needed every 600 hours, leading to unplanned downtime at the worst possible time of year. After switching to the Splined Yoke 05 Push Pin from our catalogue, the maintenance interval extended to over 1,500 hours — a 150% improvement. The induction-hardened splined yoke teeth showed minimal wear at first inspection, and the zinc-nickel coated push pins continued to operate smoothly through the notoriously wet Fenland autumn. Fenland Grains have since standardised on the 5.0505D variant for all their 1 3/8 inch Z21 PTO lines, and they report an estimated annual saving of £2,800 in parts and unscheduled labour costs. Their procurement team described the product as “the most cost-effective splined yoke upgrade we have made in the last decade.”

The Splined Yoke 05 Push Pin is designed to integrate seamlessly with our full family of PTO drive shafts. Pair your splined yoke with the series that best matches your torque, speed, and length requirements:

Our Manufacturing Facility and Custom Engineering Capability

Every Splined Yoke 05 Push Pin is produced in our dedicated PTO components plant, which houses a full closed-die forging line, CNC broaching centre, induction hardening station, and automated dimensional inspection cell. The facility operates under ISO 9001:2015 quality management and maintains full batch traceability from raw steel coil through to finished, packaged yoke. For buyers in the United Kingdom who need non-standard bore sizes, modified push pin lengths, special coatings, or bespoke spline profiles not listed in our standard catalogue, our engineering team offers a complete custom design and manufacturing service. Typical lead time for custom splined yoke orders is four to six weeks from drawing approval to dispatch. Whether you need a single prototype or a production batch of 10,000 pieces, our flexible manufacturing cell can accommodate the volume. All custom splined yoke units undergo the same hardness, dimensional, and salt-spray testing protocols applied to catalogue products, so quality remains consistent regardless of batch size.

Serving PTO Drive Shaft Customers Across the United Kingdom

We supply the Splined Yoke 05 Push Pin and the wider PTO drive shaft catalogue to agricultural dealers, OEM manufacturers, and end-user farm workshops throughout England, Scotland, Wales, and Northern Ireland. Regular shipments reach distribution hubs in Bristol, Leeds, Glasgow, and Belfast, with next-day pallet delivery available to most mainland postcodes via DPD and Palletways. Our UK-based technical support line is staffed by engineers who understand British farming conditions — from the heavy clay soils of the South East to the steep grazing land of the Lake District — and can recommend the correct yoke series for any PTO application. Trade account pricing, consolidated monthly invoicing, and scheduled call-off agreements are available for fleet operators and dealer networks who purchase splined yoke push pin components on a recurring basis.
