Splined Yoke 07-Push Pin

Rapid Implement Changeover

The spring-loaded push-pin releases the yoke in under three seconds, removing the need for tools. On busy mixed farms across Yorkshire and the East Midlands, this adds up to hours saved per season.

Alloy Steel Construction

Heat-treated alloy steel provides a case hardness that resists spline wear under continuous 540 or 1000 RPM operation while keeping the yoke body tough enough to handle the shock loading typical of stone-strewn UK arable fields.

Wide Series Compatibility

Available in B, D, G, C, and E spline profiles across multiple series (1 through 8), the Splined Yoke 07 Push Pin integrates with the broadest range of European tractor gearbox stubs, including ASAE/CAT 1, 2, and metric profiles.

Positive Retention Safety

The push pin cannot disengage under rotational load. The spring pre-load is calibrated to require deliberate operator action, meeting the CE Machinery Directive requirements commonly enforced across England, Scotland, and Wales.

Greaseable Pin Housing

The pin housing is designed with a grease port compatible with standard agricultural grease nipples. Regular greasing intervals — recommended every 8 operating hours — keep the pin sliding freely even in wet, muddy UK field conditions where corrosion is a constant challenge.

Drop-In Replacement Part

Dimensional compatibility with major European OEM drive shaft assemblies makes the Splined Yoke 07 Push Pin a straightforward service replacement. UK dealers and farm machinery contractors can stock a small range of series codes to cover the majority of implement fitments on a mixed fleet.

⚙ Operating Principle

When the yoke bore is aligned with a PTO stub shaft, the push pin — held under spring tension — travels radially inward into the shaft retention groove. The engagement depth is governed by the bore geometry of the yoke and the groove dimensions on the shaft, ensuring a positive mechanical lock under torque. To release, the operator applies axial finger force to the pin head, compressing the spring and withdrawing the pin from the groove, allowing axial extraction of the shaft without rotation. The mechanism is entirely mechanical, requiring no electrical, hydraulic, or pneumatic actuation — a significant advantage in wet or muddy field environments across the British countryside where electronic actuators are prone to failure.

🔨 Material & Surface Treatment

The yoke body is cold-forged from medium-carbon alloy steel — typically a 20CrMnTi or equivalent grade — which combines high tensile strength with sufficient ductility to absorb sudden torque spikes. After rough machining, the spline bore undergoes CNC broaching to achieve tight DIN tolerances on tooth form and pitch diameter. The component is then carburised and case-hardened to a surface hardness of 58–62 HRC while maintaining a core hardness around 30–35 HRC, providing the ideal gradient between wear resistance at the spline interface and fracture toughness at the root. A zinc phosphate coating followed by oil treatment provides the baseline corrosion protection required for outdoor agricultural storage in the damp UK climate.

🌿 Application Scenarios in the UK

The Splined Yoke 07 Push Pin is routinely used on rotary toppers and finishing mowers on UK golf courses and estate management properties, as well as on slurry tanker agitator drives on dairy farms across Devon and Cheshire. Round baler input drives, flail mulcher PTO shafts, and small square baler pickup mechanisms are common fitments. In light industrial settings, the component appears on wood chipper feed drives, concrete mixer PTO attachments, and hydraulic pump drives mounted behind compact utility tractors. Because the series covers a C-to-E bore range reaching 1 3/4″ Z20, it bridges the gap between medium and heavy-duty tractor categories, making it a genuinely versatile part for UK agricultural merchants and farm machinery dealers to stock.

Heavy-duty T Series shafts are built for high-torque applications such as large rotary tillers and commercial spreaders, with robust cross-and-bearing kits rated for the most demanding cultivation schedules.

“We run a tight schedule on our Norfolk farm and cannot afford downtime swapping implements. The push-pin release works perfectly every time, even in January field conditions. We have not had a stuck yoke in two seasons since switching.”

“As a dealer stocking spare parts for farms across Shropshire, I need components that are consistent batch to batch. The dimensional accuracy on these yokes is excellent — I have never had a customer return one for a fitment issue.”

“We supply wood chipper PTO drive shafts to estate forestry operations across Scotland. The 07 Push Pin yoke in Series 7 and 8 fits our sub-assembly perfectly. Surface finish and hardness are consistently within spec on every batch we receive.”

Which spline profile should I choose when ordering a Splined Yoke 07 Push Pin for a John Deere tractor PTO output in the UK?

John Deere tractors sold in the UK market typically use a 1 3/8″ Z6 or 1 3/8″ Z21 spline on their 540 and 1000 RPM PTO outputs respectively. The Z6 six-spline profile (F designation ending in B or D) is the most common fitment on models up to approximately 100 hp, while the Z21 twenty-one spline profile is used on higher-power models. If you are uncertain, check the tractor’s operator manual or measure the stub shaft with a profile gauge before ordering. Our technical team can assist with identification from measurements if needed.

How do I know when a Splined Yoke 07 Push Pin on my farm machinery in the East of England needs replacing?

The primary wear indicators are perceptible rotational play at the spline interface when the shaft is loaded, a sticky or slow-releasing push pin that requires more than light finger force to disengage, visible fretting or metallic debris around the bore, and measurable backlash exceeding manufacturer tolerance when the shaft is rocked under load. In arable applications in the East of England, particularly those running cultivator drives through stony soils, annual inspection is recommended. Many operators carry a spare yoke during the busy spring cultivation and drilling period to avoid unexpected downtime.

Where can I find a reliable Splined Yoke 07 Push Pin supplier that ships to Scottish farms with short lead times?

We supply directly to Scottish farms and agricultural machinery dealers throughout the Highlands, Aberdeenshire, Perthshire, and the Scottish Borders. Our standard despatch time for stock series is 3–5 working days to mainland Scotland via standard pallet courier services. For urgent replacement requirements — particularly during harvest or silage-cutting periods — express despatch options are available. Contact our sales team to discuss stocking agreements for Scottish dealers who want to hold local inventory of the most common Series 5 through Series 8 spline codes.

What is the difference between the B, D, G, C, and E spline variants on the Splined Yoke 07 Push Pin and how do I choose the right one for my implement?

The letter suffix denotes the spline profile type rather than a quality grade. B and D variants use the 1 3/8″ nominal bore diameter, with Z6 (6-tooth) and Z21 (21-tooth) tooth counts respectively. G variants use the metric 8-32X38X6 profile, which is common on continental European implements. The C and E variants step up to a 1 3/4″ nominal bore, available in Z6 and Z20 tooth counts, for higher torque applications such as large round balers and heavy duty flail mulchers. Your implement’s connection documentation or a direct measurement of the shaft stub will identify the correct suffix for your application.
